1. System Configuration

1.2 Features

Option card support:

The T1-40/T1-40S has two slots for the option card, which is approximately 1/2 the size

of a credit card. The following eight types of the option cards are available.

· 16 points DC input

· 16 points DC output

· 8 DC inputs + 8 DC outputs

· 1 channel analog input (0 to 5 V/0 to 20 mA)

· 1 channel analog input (±10 V)

· 1 channel analog output (0 to 20 mA)

· 1 channel analog output (±10 V)

· Field network TOSLINE-F10 remote

By using the 16 points input and 16 points output cards, the T1-40/T1-40S can control

up to 72 I/O points without enlarging the mounting space.

Built-in high speed counter:

Two single-phase or one quadrature (2-phase) pulses can be counted. The acceptable

pulse rate is up to 5 kHz. (DC input type only)

Built-in analog setting adjusters:

Two analog setting adjusters are provided on the T1/T1S. This allows operators to

adjust time or other control parameters easily using a screwdriver.

High speed processing:

Sophisticated machine control applications require high speed data manipulations. The

T1/T1S is designed to meet these requirements.

· 1.4 ms per contact

· 4.2 ms per 16-bit transfer

· 2.3 ms per coil

· 6.5 ms per 16-bit addition

The T1/T1S also supports interrupt input function (DC input type only). This allows

immediate operation independent of program scan.

High performance software:

The T1 offers 17 basic ladder instructions and 76 function instructions. The T1S offers

21 basic ladder instructions and 99 function instructions.

Subroutines, Interrupt functions, Indirect addressing, For/Next loops, Pre-derivative

real PID, etc. are standard on the T1/T1S. These functions allow the T1/T1S to be

applied to the most demanding control applications.

Battery-less operation:

The T1/T1S has a standard built-in EEPROM, permitting operation without need of a

battery. Also, the variable data can be written into and/or read from the EEPROM,

providing completely maintenance-free back-up operation.

This function is an important feature for OEMs, because it can eliminate the need for

changing the battery every few years. The cost of the battery is also eliminated.

16 ^{T1/T1S User’s Manual}

6F3B0250

1. System Configuration

Pulse output / PWM output:

One point of variable frequency pulses (max. 5 kHz) or variable duty pulses can be

output. These functions can be used to drive a stepping motor or to simulate an analog

output. (DC input type only)

Built-in computer link function:

The T1/T1S’s RS-232C programmer port can accept the computer link protocol (data

read/write). This results in easy connection to a higher level computer, an operator

interface unit, etc.

The parity setting of the programmer port can be selected either odd or none. The none

parity mode is provided especially for telephone modem connection. Using modems,

remote programming/monitoring is available.

Real-time control data link network:

By inserting the TOSLINE-F10 remote card (option card) into the T1-40/T1-40S, high

speed data link network can be established. In this network, upper T-series PLC model

(T2/T2E/T2N or T3/T3H) works as master and up to 16 T1-40/T1-40Ss can be

connected as remote. Each T1-40/T1-40S can exchange data with the master through

1 word input and 1 word output. The transmission speed can be selected either 750

kbps or 250 kbps.

The T1/T1S is equipped with brackets for mounting on a standard 35 mm DIN rail. The

T1/T1S can be mounted on a DIN rail as well as screw mounting.

On-line program changes: (T1S only)

When the T1S’s memory mode is set to 4 k steps mode, on-line (in RUN mode)

program changes are available. Furthermore, program writing into the built-in

EEPROM is also available in RUN mode. These functions are useful in program

debugging stage.

Real-time clock/calendar function: (T1S only)

The T1S has the real-time-clock/calendar function (year, month, day, day of the week,

hours, minutes, seconds) that can be used for performing scheduled operations, data

gathering with time stamps, etc. The real-time-clock/calendar data is backed up by

built-in capacitor for power off. The back-up period is more than 7 days at 25 °C.

RS-485 multi-purpose communication port: (T1S only)

The T1S has an RS-485 multi-purpose communication port. Using this port, one of the

following communication modes can be selected.

· Computer link mode: T-series computer link protocol can be used in this mode.

Up to 32 T1Ss can be connected to a master computer. By using this mode,

MMI/SCADA system can be easily configured.

· Data link mode: Two PLCs (any combination of T1S, T2E or T2N) can be directly

linked together. This direct link is inexpensive, easily configured and requires no

special programming.

· Free ASCII mode: User defined ASCII messages can be transmitted and

received through this port. A terminal, printer, bar-code reader, or other serial

ASCII device can be directly connected.

T-Series Program Development System (T-PDS)

The T-Series Program Development System (T-PDS) is a software which runs on any

IBM-PC compatible personal computers such as Toshiba’s Notebook computers. The

same T-PDS software supports on-line/off-line programming, debugging and program

documentation for all the T-Series programmable controllers T1/T1S, T2/T2E/T2N and

T3/T3H.

· User-friendly program editor includes cut & paste, address search & replace,

program block move/copy, etc.

· Group programming - part program development by multiple designers and

merging them into a complete program - enhance the software productivity.

· Powerful monitoring, I/O force and data set functions fully support your program

debugging.

· Documentation of programs with commentary makes your maintenance work easy.

· Remote monitoring/programming via modem (radio/phone) is possible.

Program Storage Module (RM102)

The program storage module (RM102) is an

external memory for storing the T1/T1S

program. By using the RM102, program saving

from the T1/T1S to the RM102, and program

loading from the RM102 to the T1/T1S can be

done without need of a programmer.

Because the RM102 has an EEPROM,

maintenance-free program storage and quick

saving/loading are available.

Multi-drop adapter (CU111)

The T1/T1S’s RS-232C programmer port

supports the computer link function.

When two or more T1/T1Ss are connected with

a master computer, the multi-drop adapter

(CU111) can be used. (One-to-N configuration)

The CU111 is an RS-232C/RS-485 converter

specially designed for the T1/T1S’s

programmer port.

3. I/O Application Precautions

(2) Minimum ON/OFF time of the input signal

The following conditions guarantee correct reading of the ON/OFF state of the input

signal:

Input ON time: ON delay time + the time for one scan

Input OFF time: OFF delay time + the time for one scan

The ON and OFF times of the input signals must be longer than these intervals.

(3) Increasing the contact current

The reliability of some contacts cannot be guaranteed by the specified input current. In

this case, install an external bleeder resistor to increase the contact current.

(5) Countermeasures against leakage current

When a switch with an LED or an AC output sensor is used, the input sometimes cannot

recognize that the switch is off due to the current leakage. In this case, install a bleeder

resistor to reduce input impedance.

(b) The current must be within the allowable range when the sensor is switched on.

sensor is switched on times three.

Note) The above solution cannot be applied to the T1-16 dry contact input.

(6) Countermeasures against induced current

With ac input signals, if the external cable is long or if a multi-core cable is used, an

induced current can flow from the charged wire to the open wire, in proportion to the

capacities of the cables. In this case, sometimes the voltage reaches the level of the ON

input even though the contact is open, causing the input to malfunction for no apparent

reason.

The usual practice when this happens is to reduce input impedance. Install a resistor or a

resistor and capacitor between the input and common terminals, or use shielded cables.

Such precautions are necessary when dealing with a large number of ac input signals.

3. I/O Application Precautions

3.2 Application precautions for output signals

Configure emergency stop and safety interlocking circuits outside the T1/T1S.

Otherwise, malfunction of the T1/T1S can cause injury or serious accidents

WARNING

CAUTION

1. Turn on power to the T1/T1S before turning on power to the loads. Failure

to do so may cause unexpected behavior of the loads.

2. Configure the external circuit so that the external 24 Vdc power required

for the transistor output circuits and power to the loads are switched on/off

simultaneously. Also, turn off power to the loads before turning off power to

the T1/T1S.

3. Install fuses appropriate to the load current in the external circuits for the

outputs. Failure to do so can cause fire in case of load over-current.

(1) 2 points of solid-state output

The leading 2 points of output (Y020 and Y021) are solid-state outputs, transistors on the

DC input types and triacs on the AC input types.

These solid-state outputs are suited for frequent switching applications.

Note that the specifications of the solid-state outputs and other outputs (relays) are

different.

(2) Switching life of output relays

Expected relay life is more than 100,000 electrical cycles at rated maximum voltage and

current, and more than 20 million mechanical cycles. The expected contact life (electrical

cycles) is shown on the table below.

4.3 Wiring terminals

1. Turn off power before wiring to minimize the risk of electrical shock.

CAUTION

2. Exposed conductive parts of wire can cause electrical shock. Use

crimp-style terminals with insulating sheath or insulating tape to cover

the conductive parts. Also close the terminal covers securely on the

terminal blocks when wiring has been completed.

3. Turn off power before removing or replacing units, modules, terminal

blocks or wires. Failure to do so can cause electrical shock or damage

to the T1/T1S and related equipment.

The terminal arrangement of each T1 Series model are shown below.

The terminal screw size is M3.5. Use crimp-style terminals of 7 mm width or less useable

for M3.5.

The terminal blocks of the T1-16 are not removable (fixed). On the other hand, the

terminal blocks of the T1-28, T1-40 and T1-40S are removable. However, be sure to turn

off power before removing or replacing the terminal blocks.

4.4 Grounding

1. Turn off power before wiring to minimize the risk of electrical shock.

CAUTION

2. Operation without grounding may cause electrical shock or malfunction.

Connect the ground terminal on the T1/T1S to the system ground.

The optimum method for grounding electronic equipment is to ground it separately from

other high-power systems, and to ground more than one units of electronic equipment

with a single-point ground.

Although the T1/T1S has noise immunity to be used in industrial operating conditions,

grounding is important for safety and reliability.

Check the grounding against the following criteria.

1. The T1/T1S must not become a path for a ground current. A high-frequency current is

particularly harmful.

2. Equalize the ground potentials when the expansion rack or unit is connected. Ground

the T1/T1S and the expansion rack or unit at a single point.

3. Do not connect the ground of the T1/T1S to that of high-power systems.

4. Do not use a ground that has an unstable impedance, such as painted screws, or

ground subject to vibration.

The grounding marked terminal (see below) is provided on the T1/T1S basic unit and the

expansion unit for grounding purpose.

5. Operating System Overview

5.1 Operation modes

The T1/T1S has three basic operation modes, the RUN mode, the HALT mode and the

ERROR mode. The T1/T1S also has the HOLD and RUN-F modes mainly for system

checking.

RUN:

The RUN mode is a normal control-operation mode.

In this mode, the T1/T1S reads external signals, executes the user program

stored in the RAM, and outputs signals to the external devices according to the

user program. It is in the RUN mode that the T1/T1S performs scans the user

program logic, which is the basic operation of a PLC.

In case of the T1S, program changes and EEPROM write are possible while

the T1S is in the RUN mode. Refer to section 6.9.

On the other hand, in case of the standard T1, program changes and

EEPROM write are not possible in the RUN mode.

HALT:

The HALT mode is a programming mode.

In this mode, user program execution is stopped and all outputs are switched

off.

Program loading into the T1/T1S is possible only in the HALT mode.

For the standard T1, program changes and EEPROM write are possible only

when the T1 is in the HALT mode.

ERROR: The ERROR mode is a shut-down mode as a result of self-diagnosis.

The T1/T1S enters the ERROR mode if internal trouble is detected by self-

diagnosis. In this mode, program execution is stopped and all outputs are

switched off. The cause of the shut-down can be confirmed by connecting the

programming tool.

To exit from the ERROR mode, execute the Error Reset command from the

programming tool, or cycle power off and then on again.

HOLD: The HOLD mode is provided mainly for checking the external I/O signals.

In this mode, user program execution is stopped, with input and output

updating is executed. It is therefore possible to suspend program execution

while holding the output state. Moreover, a desired output state can be

established by setting any data by using the programming tool.

RUN-F: The RUN-F mode is a forced RUN mode provided for program checking.

This mode is effective when using the expansion I/Os.

Deferent from the normal RUN mode, the RUN-F mode allows operation even

if the registered option cards, expansion unit and/or I/O modules are not

actually mounted.

82 ^{T1/T1S User’s Manual}

6F3B0250

5. Operating System Overview

5.2 About the built-in EEPROM

The T1/T1S is equipped with a built-in EEPROM and a RAM as standard features.

The user program is stored in the EEPROM so that the user program can be maintained

without the need of a battery. A part of the Data register can also be stored in the

EEPROM.

The table below shows the contents stored in the built-in EEPROM.

The user program and the data stored in the EEPROM is transferred to the RAM when

power is turned on. Subsequent program execution is done based on the RAM contents.

Program editing is also performed on the RAM contents.

Therefore, if the program is modified, it is necessary to issue the EEPROM Write

command from the programming tool. Otherwise, the modified program is over-

written by original EEPROM contents when the power is turned off and on again.

5. Operating System Overview

In case of the T1S, Special register SW55 is used to specify the number of Data registers

to be stored in the EEPROM. The allowable setting value is 0 to 2048.

The table below shows the correspondence between the SW55 value and Data registers

saved in the EEPROM.

When the EEPROM Write command is executed, the T1S checks the value of SW55 and

saves the Data registers into the EEPROM depending on the SW55 value. The value of

SW55 itself is also saved in the EEPROM.

At the initial load or the EEPROM Read command is executed, the T1S checks the value

for SW55 in the EEPROM and transfers the corresponding number of data to the Data

registers of the RAM.

NOTE

(1) The EEPROM has the life limit for writing. It is 100,000 times. Pay

attention not to exceed the limit. If the number of execution of EEPROM

Write command exceeds 100,000 times, EEPROM alarm flag (S007)

comes ON.

(2) In the T1S, if the EEPROM Write command is executed in RUN mode,

only the user program is written into the EEPROM.

(3) The data in the EEPROM (D0000 to D0511 or D0000 to D2047) can also

be read or written by using the program instruction (FUN236 XFER

instruction).

(4) The SW55 setting is available only for the T1S.

Hardware check:

Performs checking and initialization of the system ROM, the system RAM and the

peripheral LSIs.

Initial load:

Transfers the user program and user data from the EEPROM to the RAM. (Refer to

section 5.2)

Initializes registers and devices as shown below.

Initialization

External input (X/XW)

Forced inputs are retained. Others are cleared to 0.

External output (Y/YW) Forced coil devices are retained. Others are cleared to 0.

Auxiliary device/register User specified retentive registers and forced coil devices

(R/RW)

are retained. Others are cleared to 0.

(C./C)

cleared to 0.

Data register (D)

User specified retentive registers are retained. Others are

cleared to 0.

Index register (I, J, K)

Cleared to 0.

NOTE

(1) When the data stored in the EEPROM (Data registers) are used, these

registers should be specified as retentive. Otherwise, these data are

transferred from EEPROM to RAM, but then cleared to 0 at the

initialization.

(2) The data in the retentive registers are stored in RAM and backed up by

built-in capacitor. The back-up period is 6 hours or more at 25 °C (T1), or

168 hours or more at 25 °C (T1S).

The T1/T1S checks the validity of the retentive data at the power-up

initialization, and if they are not valid, sets the special device (S00F) to ON.

Therefore, it is recommended to check the status of S00F in the user

program and to initialize the retentive registers if S00F is ON.

(3) The retentive registers can be set by the programming tool for RW, T, C

and D registers. The registers from address 0 to the designated address

for each type are set as retentive registers. Refer to the separate manual

for the programming tool for setting the retentive registers.

(4) The input force and the forced coil are functions for program debugging.

For details, refer to section 6.7.

5. Operating System Overview

Self-diagnosis:

Checks the proper operation of the T1/T1S itself. If an error has detected and cannot be

recovered by re-tries, the T1/T1S moves into ERROR mode. For the self-diagnosis

items, refer to section 10.2.

Mode control:

Checks the mode control switch status and the mode control request commands from

the programming tool.

The scan mode - floating scan or fixed-time scan - is also controlled hear.

NOTE

The floating scan:

When one scan is finished, immediately starts the next scan. The scan time is

shortest, but may vary depending on the program execution status.

Scan time

The fixed-time scan:

The scan operation is started every user-specified time. The time setting range

is 10 to 200 ms (10 ms units). If an actual scan needs longer time than the

setting time, it works as the floating scan.

Scan time (50 ms fixed) Scan time (50 ms fixed)

(idling)

Program check:

At the beginning of the RUN mode, the user program is compiled and its validity is

checked.

I/O update:

Reads the external input signals into the external input devices/registers (X/XW), and

sends the data of the external output devices/registers (Y/YW) to the external output

circuits. Then the outputs (relays, etc.) changes the states and latches until the next I/O

update timing.

The states of the forced input devices are not updated by this operation.

Timer update:

Updates the timer registers which are activated in the user program, and the timing

devices (S040 to S047).

^{Basic Hardware and Function}89

6F3B0250

5. Operating System Overview

User program execution:

Executes the programmed instructions from the beginning to the END instruction.

This is the essential function of the T1/T1S.

In this section, only the main program execution is mentioned. For other program types,

such as timer interrupt, etc., refer to section 6.5.

Peripheral support:

Supports the communications with the programming tool or an external devices

connected by the computer link function. The time for this operation is limited within

approx. 2 ms in the floating scan mode, and within allowable idling time in the fixed-time

scan mode.

In case of the T1S, if the special relay S158 is set to ON, the peripheral support priority

mode is selected. In the peripheral support priority mode, the peripheral support time is

not limited. As the result, the communication response is improved although the scan

time becomes long at the time.

6.2 Index modification

When registers are used as operands of instructions, the method of directly designating

the register address as shown in Example 1) below is called ‘direct addressing’.

As opposed to this, the method of indirectly designating the register by combination with

the contents of the index register (I, J, or K) as shown in Example 2) below is called

‘indirect addressing’. In particular, in this case, since the address is modified using an

index register, this is called ‘index modification’.

Example 1)

¾[ RW10 MOV D1000 ]¾

Data transfer instruction

Transfer data of RW10 to D1000

Example 2)

¾[ RW10 MOV D0000 ]¾

Data transfer instruction (with index modification)

Transfer data of RW(10 + I) to D(0000 + J)

(If I = 3 and J = 200, the data of RW13 is transferred to D0200)

There are 3 types of index register, I, J and K. Each type processes 16-bit integers

(-32768 to 32767). There are no particular differences in function between these 3 types

of index register.

There is no special instruction for substituting values in these index registers. These are

designated as destination of data transfer instructions, etc.

¾[ 00064 MOV I ]¾

(substitutes 64 in index register I)

¾[ D0035 MOV J ]¾

(substitutes the data of D0035 in index register J)

¾[ RW20 + 00030 ® K ]¾ (substitutes the result of addition in index register K)

NOTE

(1) The index modification is available for RW, T, C and D registers.

(2) If index registers are used as a double-length register, only the

combinations J×I and K×J are allowed.

104 ^{T1/T1S User’s Manual}

6F3B0250

6. Programming Information

The followings are examples of index modifications.

When I = 0, it designates RW10.

When I = 1, it designates RW11.

When I = -1, it designates RW09.

When I = 10, it designates RW20.

When I = -10, it designates RW00.

RW10

When J = 0, it designates D0201×D0200.

When J = 1, it designates D0202×D0201.

When J = 2, it designates D0203×D0202.

When J = -1, it designates D0200×D0199.

When J = -2, it designates D0199×D0198.

D0201×D0200

Be careful that the registers do not exceed the address range by the index

modification. The address range is not checked by the T1/T1S.

CAUTION

NOTE

Substitutions of values into index registers and index modifications can be

used any times in a program. Normally, the program will be easier to see if a

value substitution into an index register is positioned immediately before the

index modification.

In the T1S, the validity of the clock/calendar is checked. If the data is not valid by excess

power off period, special relay S00A is set to ON. Therefore, when the clock/calendar is

used, it is recommended to check the status of S00A in the user program.

Setting the clock/calendar:

To set the clock/calendar data, the following 2 ways are available. In both cases, the

week data is automatically calculated.

(a) Setting the clock/calendar data on the system information screen of the

programming tool.

(2) Using the Calendar Set instruction (CLND) in the user program.

6.4 I/O allocation

The external input signals are allocated to the external input devices/registers (X/XW).

The external output signals are allocated to the external output devices/registers (Y/YW).

The register numbers of the external input and output registers are consecutive. Thus

one register number can be assigned for either input or output.

As for the T1/T1S basic unit, I/O allocation is fixed as follows.

Any operation for the I/O allocation are not required if only the T1/T1S basic unit is used.

However, if the option cards, the Expansion unit and/or the T2 I/O modules are used with

the T1-40/T1-40S, the I/O allocation operation is necessary. For this information, refer to

the separate manual for Expansion I/O.

^{Basic Hardware and Function}107

6F3B0250

6. Programming Information

Internally, the T1/T1S has an information called ‘I/O allocation table’ in its memory. This

I/O allocation table shows the correspondence between I/O hardware and software, i.e.

The contents of the I/O allocation table are as follows.

Slot

I/O type

X+Y 4W

PU slot must be blank

Slot 0 is for basic unit (XW00, XW01, YW02 and

YW03 are assigned internally)

Slots 1 to 3 are reserved for option cards

Slots 4 and 5 are reserved for Expansion unit

Slots 4 to 7 are reserved for T2 I/O modules

The T1/T1S operating system automatically sets the I/O type ‘X+Y 4W’ on the slot 0

position when the memory clear is executed for the T1/T1S.

When the T1/T1S program is developed in off-line, the above I/O allocation table should

be set before programming. For this operation (called manual I/O allocation), refer to the

programming tool manual.

6.5 T1S memory mode setting

The program capacity of the T1S is 8 k steps. However, user can set the T1S’s program

capacity to 4 k steps. It is called the T1S’s memory mode.

That is, the T1S has two memory modes, 8 k mode and 4 k mode.

In the 4 k mode, on-line program changes become available, although the program

capacity is limited to 4 k steps. Refer to section 6.9 for the on-line debug support

functions.

To set the T1S’s memory mode, write 4 k or 8 k on the Program Size Setting of the

System Parameters using the programming tool. Then execute the EEPROM write

command.

NOTE

There is no memory mode setting for the standard T1. The program capacity of

the standard T1 is 2 k steps fixed.

6.6 User program configuration

A group of instructions for achieving the PLC-based control system is called ‘user

k steps capacity for storing the user program.

A ‘step’ is the minimum unit which composes an instruction. Number of steps required for

one instruction is depending on the type of instruction. Refer to section 7.1.

6. Programming Information

System information

System information is the area which stores execution control parameters. The following

contents are included in the system information.

(1) Machine parameters (hardware type, memory type)

(2) User program information (program ID, system comments, number of steps used)

(3) Passwords

(4) Retentive register area information

(5) T1S program memory mode, 4 k steps or 8 k steps (T1S only)

(6) Execution control parameters (scan mode, timer interrupt interval)

(7) Station number setting for programmer port (T1), or RS-485 port communication

parameters (T1S)

(8) I/O allocation table

(9) Input force table

The system information is stored in the built-in EEPROM. Therefore, when these

information is modified, the EEPROM write operation is necessary. Otherwise, these are

over-written by original EEPROM contents at the next initial load timing.

User program

The T1 has a capacity of 2 k steps of the user program. And the T1S has a capacity of 8

k steps of the user program.

The user program is stored by each program types as shown in the following diagram,

and is managed by units called blocks in each program types.

The I/O interrupt program is also the highest priority task. It is executed immediately

when the interrupt factor is generated, with suspending other operation.

the following 4 types I/O interrupt programs are supported in the T1/T1S.

(1) I/O interrupt #1

The I/O interrupt #1 is used with the high speed counter function. When the count

value reaches the preset value, etc., the I/O interrupt #1 is activated immediately

with suspending other operation. The end of the I/O interrupt #1 is recognized by the

IRET instruction. For detailed information, refer to section 8.3.

(2) I/O interrupt #2

The I/O interrupt #2 is also used with the high speed counter function. Refer to

section 8.3 for details.

(3) I/O interrupt #3

The I/O interrupt #3 is used with the interrupt input function. When the state of the

interrupt input is changed from OFF to ON (or ON to OFF), the I/O interrupt #3 is

activated immediately with suspending other operation. The end of the I/O interrupt

#3 is also recognized by the IRET instruction. For detailed information, refer to

section 8.4.

(4) I/O interrupt #4

The I/O interrupt #4 is also used with the interrupt input function. Refer to section 8.4

for details.

If an interrupt factor is generated while other interrupt program is executing (including the

timer interrupt), the interrupt factor is held. Then it will be activated after finishing the

other interrupt program execution.

If two or more interrupt factors are generated at the same time, the priority is as follows.

Timer > I/O #1 > I/O #2 > I/O #3 > I/O #4

efficient data-processing program, ladder diagram which are combinations of relay

symbols and function blocks are used.

The ladder diagram program is constructed by units called ‘rung’. A rung is defined as

one network which is connected each other.

Rung number

Rung

The rung numbers are a series of numbers (decimal number) starting from 1, and cannot

be skipped. There is no limit to the number of rungs.

The size of any one rung is limited to 11 lines ´ 12 columns.

A example of a ladder diagram program is shown below.

When X005 is ON or the data of D0100 is greater than 200, Y027 comes ON.

Y027 stays ON even if X005 is OFF and the data of D0100 is 200 or less.

Y027 will come OFF when X006 comes ON.

6.8 Program execution sequence

The instructions execution sequence is shown below.

(1) They are executed in the sequence from block 1 through the final block which

contains the END instruction (or IRET in an interrupt program).

(2) They are executed in the sequence from rung 1 through the final rung in a block

(or the END instruction).

(3) They are executed according to the following rules in any one rung.

• When there is no vertical

connection, they are

executed from left to right.

‚ When there is an OR

connection, the OR logic

portion is executed first.

ƒ When there is a branch, they

are executed in the order from

the upper line to the lower line.

„ A combination of ‚ and ƒ

above.

The instructions execution sequence in which function instructions are included also

follows the above rules. However, for program execution control instructions, such as

jumps (JCS), loops (FOR-NEXT), subroutines (CALL-SUBR-RET), it will depend the

specifications of each instruction.

6.9 On-line debug support functions

The following on-line (during RUN) functions are supported in the T1/T1S for effective

program debugging.

On-line function

T1S

4 k mode

Yes

8 k mode

Yes

Force function

Yes

Sampling trace function

Changing timer /counter preset

Yes

Changing constant operand of

function instruction

Yes

Program changing in edit mode

EEPROM write command

Yes

NOTE

Refer to section 6.5 for 4 k/8 k mode of the T1S.

Force function

Two types of force functions are available, input force and coil force.

The input force is used to disable the external input signals. When an external input

device is designated as forced input, the ON/OFF state of the device can be changed

manually by using the data setting function of the programming tool, regardless of the

corresponding external signal state. The input force designation is available for the

external input devices (X).

The coil force is used to disable the coil instruction. When a coil instruction on the

program is designated as forced coil, the ON/OFF state of the coil device can be

changed manually by using the data setting function of the programming tool, regardless

of the coil circuit execution status.

On the programming tool, the forced input and forced coil are expressed as follows.

Forced input

X005

Normal

Y023

NOTE

Forced

If EEPROM write operation is executed with remaining the force designation,

the force designation is also saved into the built-in EEPROM. Because the

force function is debugging function, release all force designation before

executing the EEPROM write operation. The force batch release command is

available when the T1/T1S is in HALT mode.

6. Programming Information

Sampling trace function

The sampling trace function collects the status of specified devices or register at every

specified sampling timing. The collected data can be displayed on the programmer (T-

PDS) screen in the format of timing chart (for devices) or trend graph (for register). The

minimum sampling timing is the T1/T1S’s scan cycle.

This function is useful for program debugging and troubleshooting.

Sampling target

Devices (up to 8) or

256 times for device

128 times for register

Devices (up to 8) and

Registers (up to 3)

256 times

Sampling capacity

The collected data is stored in the T1/T1S internal buffer.

The buffer works as a ring buffer, and latest collected data can be displayed.

The sampling start/stop condition (arm condition) and the collection timing (trigger

condition) can be specified by status changing of devices.

For detailed key operations for arm/trigger conditions setting on the T-PDS, refer to the

manual for T-PDS.

T-PDS screen example of device timing chart

NOTE

(1) On the T-PDS, select ‘3 registers + 8 devices’ as the sampling type.

(2) As the arm and trigger conditions, register values cannot be used.

(3) The After times setting is not effective for the T1/T1S.

6. Programming Information

Timer/counter preset value (constant data) changing

The preset value (constant data) of timer or counter instruction can be changed in on-line

(during RUN) by using the programming tool.

Function instruction constant operand changing (T1S only)

The constant operand of function instruction can be changed in on-line (during RUN) by

using the programming tool.

Device changing (T1S only)

The device of contact or coil instruction can be changed in on-line (during RUN) by using

the programming tool.

On-line program changing (T1S only)

When the T1S’s memory mode is 4 k mode, the program can be changed using normal

edit mode. (rung by rung)

In the on-line program changing, it is not allowed to change the number or order of the

following instructions.

END, MCS, MCR, JCS, JCR, FOR, NEXT, CALL, SUBR, RET, IRET

NOTE

The above on-line functions are performed on the RAM memory. Therefore,

when program has been changed, execute the EEPROM write operation

before turning off power. Otherwise, program stored in the EEPROM will be

overwritten.

On-line EEPROM write (T1S only)

The EEPROM write is possible in on-line (during RUN) as well as in HALT mode.

In the on-line EEPROM write, user data is not written into the EEPROM.

During this operation, the T1S’s scan time becomes longer. However, as it has the time

limit per scan, the T1S’s control operation is not stopped.

NOTE

In case of the standard T1, the EEPROM write is possible only in the HALT

mode.

6. Programming Information

6.10 Password protection

The T1/T1S has the password function to protect the user program and data from

unauthorized operations.

There are four levels of protection. Accordingly, three levels of passwords can be

registered to control the protection levels.

These passwords are stored in the built-in EEPROM. Therefore, if you entered, changed

or cleared the passwords, the EEPROM write operation is necessary.

The outline of the protection levels are shown below. For details, refer to the manual for

the programming tool.

Protection level 4 (disabled functions)

· Writing register/device data

· Writing system information

· I/O allocation

Protection level 3 (disabled functions)

· Reading program

Strict

· Program write into EEPROM

Protection level 2 (disabled functions)

· Clear memory

· Writing/loading program

· T1/T1S operation mode changes (by programming tool)

· Setting/changing passwords

Protection level 1 (disabled functions)

· None (all functions are available)

When the level 1, 2 and 3 passwords are registered, the T1/T1S will be started as

protection level 4. In this state, for example, entering the level 2 password changes the

protection level to 2.

NOTE

When you use the password function, do not forget the level 1 password.

Otherwise, you cannot change/release the registered passwords.

MV remains unchanged.

A+5 bit 0, 1 ¬ B+8 bit 0, 1

ASV ¬ ISV

MMV ¬ MV

2. When the instruction input is ON:

Executes PID calculation every n scan which is specified by B+12. The following operation modes are

available according to the setting of A+5.

· Auto mode

This is a normal PID control mode with ASV as set value.

Set value differential limit DSV, manipulation value upper/lower limit MH/ML and differential limit DMV are

effective.

Bump-less changing from auto mode to manual mode is available. (Manual mode manipulation value MMV

is over-written by current MV automatically. MMV ¬ MV)

240 ^{T1/T1S User’s Manual}

6F3B0250

7. Instructions

· Manual mode

In this mode, the manipulation value MV can be directly controlled by the input value of MMV.

MV differential limit for manual mode DMMV is effective. MH/ML and DMV are not effective.

When mode is changed from manual to auto or cascade, the operation is started from the current MV.

· Cascade mode

This is a mode for PID cascade connection. PID is executed with CSV as set value.

Different from the auto mode, set value differential limit is not effective. Manipulation value upper/lower limit

MH/ML and differential limit DMV are effective.

Bump-less changing from cascade mode to manual mode is available. (Manual mode manipulation value

MMV is over-written by current MV automatically. MMV ¬ MV)

And, bump-less changing from cascade mode to auto mode is available. (Auto mode set value ASV is

over-written by current CSV automatically. ASV ¬ CSV)

· MV tracking

This function is available in auto and cascade modes. When the tracking designation (A+5 bit 2) is ON,

tracking input TMV is directly output as MV.

Manipulation value upper/lower limit MH/ML is effective, but differential limit DMV is not effective.

When the tracking designation is changed to OFF, the operation is started from the current MV.

Note

· PID3 instruction is only usable on the main-program.

· PID3 instruction must be used under the constant scan mode. The constant scan interval can be selected in

the range of 10 to 200 ms, 10 ms increments.

· The data handled by the PID3 instruction are % units. Therefore, process input value PVC, manipulation value

MV, etc., should be converted to % units (scaling), before and/or after the PID3 instruction. For this purpose,

the function generator instruction (FUN165 FG) is convenient.

8.3 High speed counter

8.3.1 Single phase up-counter

Function

When the count input is changed from OFF to ON, the count value is increased by 1.

When the count value reaches the set value, the count value is reset to 0, and I/O

interrupt program is activated (if the interrupt enable flag is ON). The count value is reset

to 0 when the reset input comes ON.

This counter operation is enabled while the soft-gate is ON. The count value is reset to 0

when the soft-gate is changed from ON to OFF.

The set value is set internally at the timing of the soft-gate changing from OFF to ON.

When the soft-gate is OFF, the count value can be changed by writing the data into the

set value register and setting the count preset flag to ON.

The count value range is H0000 to HFFFF (16-bit data).

Not normal

Check whether the X device

is forced or not

If it is forced, release the force designation

then execute the EEPROM write

operation.

Not forced

Check whether the I/O

allocation table is identical to

the actual I/O configuration

If identical, the T1/T1S’s internal circuit or

the input circuit may be faulty.

Not identical

Execute the automatic I/O

allocation, and check whether

the I/O allocation table is now

identical to the actual I/O

configuration

If it becomes identical, execute the

EEPROM write operation.

Still not identical

Is the allocation mismatch for

a specific option card, I/O

module, or expansion unit ?

If so, the card, module or expansion unit

may be faulty. For expansion unit, check

the expansion cable also.

Is the allocation mismatch for

all I/O modules mounted on

the expansion rack ?

If so, check the connection between the

T1/T1S basic unit and the expansion rack.

If not, the T1/T1S basic unit may be faulty.

10. Troubleshooting

10.1.5 Output check

If the output status monitored on the programming tool is normal but the external output

device (load) is not operated normally, check the following points:

Is the output status LED

changed ON/OFF according

to the program execution ?

Yes

Check the voltage between

the output terminal and its

common terminal.

It should be 0 V when the

output is ON, and it should

be the circuit voltage when

the output is OFF.

If it is the circuit voltage at the output is

ON, or if it is 0 V at the output is OFF with

the load ON, the T1/T1S’s output circuit

may be faulty.

If it is 0 V and the load is also OFF, check

the output power and the output cable

connections.

Normal

If it is not normal, check the output cable

connections.

Check the voltage at the load

If it is normal, check the specification of

the load, also check environmental factors.

Check whether the I/O

allocation table is identical to

the actual I/O configuration

If identical, the T1/T1S’s internal circuit or

the output circuit may be faulty.

Not identical

Execute the automatic I/O

allocation, and check whether

the I/O allocation table is now

identical to the actual I/O

configuration

If it becomes identical, execute the

EEPROM write operation.

Still not identical

Is the allocation mismatch for

a specific option card, I/O

module, or expansion unit ?

If so, the card, module or expansion unit

may be faulty. For expansion unit, check

If so, check the connection between the

T1/T1S basic unit and the expansion rack.

If not, the T1/T1S basic unit may be faulty.

10. Troubleshooting

10.1.6 Environmental problem

If the following improper operations occur in the controlled system, check possible

environmental factors.

(1) If an improper operation occurs synchronously with the operation of I/O devices:

The noise generated at ON/OFF of the output device (load) may be the cause of the

problem. Take necessary measures mentioned in section 3.

(2) If an improper operation occurs synchronously with the operation of surrounding

equipment or high-frequency equipment:

The noise induced in I/O signal lines may be the cause of the problem. The surge

voltage, voltage fluctuations, or differences of grounding potentials may cause the

problem, depending on the power supply system or the grounding system.

Check the operation in accordance with the precautions in section 4. For some

cases, isolation from the ground may lead to the stable operation.

(3) If an improper operation occurs synchronously with the operation of machinery:

The vibration of the equipment may cause the problem. Check that the installation

status of the units and take necessary measures.

(4) If a similar failure is repeated after the unit is replaced:

Check that no metal debris or water drops has been entered into the unit/module.

Apart from the above points, consider climatic conditions. If the ambient temperature is

beyond the specified range, stable operation of the system is not guaranteed.

^{Basic Hardware and Function}299

10. Troubleshooting

10.2 Self-diagnostic items

If an error is detected by the self-diagnostic check of the T1/T1S CPU, the error

messages and the related information shown on the following pages will be recorded in

the T1/T1S’s event history table. If the error is severe and continuation of operation is not

possible, the T1/T1S turns OFF all outputs and stops the operation (ERROR mode).

The latest 15 error messages are stored in the event history table. This event history

table can be displayed on the programming tool. (Power ON/OFF is also registered)

If the T1/T1S has entered into ERROR mode, connect the programming tool to the

T1/T1S to confirm the error message in the event history table. This information is

important to recover from a trouble. For the key operations on the programming tool to

display the event history table, refer to the separate manual for the programming tool.
