Chapter 2 Introduction

PROFIBUS

PROFIBUS is an international, vendor- independent, opening filed bus standard for a wide

range of applications in the fields of manufacturing, production, process and building

automation, and other automation control field.

The PROFIBUS family comprises three types of protocol, PROFIBUS-DP, PROFIBUS-PA and

PROFIBUS-FMS, each of them is used for different tasks:

ꢁ

PROFIBUS-DP (Decentralized Periphery): PROFIBUS-DP is a rapid and low cost

communication connection designed for high-speed data transmission at field level.

PROFIBUS-DP has widespread usage for such items as remote I/O systems, motor

control centers, and variable speed drives. It is designed and optimized especially for

communication between automation systems and decentralized peripheral devices.

ꢁ

PROFIBUS-PA (Process Automation): PROFIBUS-PA is the PROFIBUS solution for

process automation, typically with MBP-IS transmission technology. Based upon

PROFIBUS-DP, PROFIBUS-PA is an extension of the PROFIBUS-DP protocol for data

transmission. It is designed to support intrinsically safe applications and can be used

within hazardous areas, with high explosion risk using intrinsic safe MBP-IS interface.

PROFIBUS-PA is used to connect sensor and controller to the bus.

ꢁ

PROFIBUS-FMS (Fieldbus Message Specification): PROFIBUS-FMS is multiple

master communications designed for communication at the cell level. It is designed for

acyclic or cyclic data transfers at medium speed between control equipment and

cell-level controllers. FMS services open up a wide range of applications and offer a

wide range of functionality and flexibility.

The Maximum cable length in a segment depends on the transmission speed. PROFIBUS-DP

communicates at speeds from 9.6 Kbps to 12 Mbps over distances from 100 to 1,200 meters.

PD-01 PROFIBUS-DP Module

PROFIBUS-DP

PROFIBUS-DP is a PROFIBUS communication profile optimized for high-speed, time-critical

data transmission at field level using low-cost connections. PROFIBUS-DP is a suitable

substitute for conventional, costly parallel wiring of 24 V measurement signals in production

and manufacturing automation, as well as for analog 4(0) to 20mA measurement signals in

process automation.

Terminator

Bus terminator is important when connects PD-01 to PROFIBUS-DP system. This terminator

can be switched in and out via switches when the recommended bus connectors have been

used.

If extended 4-PIN socket for the connection is used, user may use the internal terminator

provided by PD-01 via setting the switch. If the switch is turned to "S" (Short), the internal

terminator is disabled, then A1 and A2, B1 and B2 are all normally close. If the switch is

turned to "R" (Resistor), the internal terminator between A1 and B1 is enabled, but A2 and B2

are disconnected from bus.

Chapter 4 Communication

NOTE:

Before reading this chapter, make sure you read chapter 3 and understand the installation of

PD-01.

PROFIBUS address

PD-01 has two rotary switches to set the PROFIBUS address, the only way

for user to set the address.

The address switches, ADDH and ADDL, allow user to set the address in a

HEX format. ADDH is used to set high 4 bits of address, and ADDL is used

to set low 4 bits of address. If both ADDH and ADDL are set to F, and PD-01

is power ON or re-power ON, then PD-01 will enter the TEST mode, the SP

LED and NET LED will be in steady orange.

NOTE:

Setting changes via address switches will not effective when PD-01 is operating. This means

the setting changes will effective after PD-01 power re-boot. Please understand this cold

restart must be initiated by toggling the power to OFF and then ON.

Parameters setting in VFD series Drives

PD-01 is designed to communicate with VFD series Drives via MODBUS communication port.

Prior to the connection, users have to set parameters below in VFD series Drives:

ꢁ

Set the communication protocol of VFD series Drives to RTU 8, N, 2.

Set the baud rate of VFD series Drives to 9600bps.

Set the frequency source for VFD series Drives to operate via RS485.

Set the operation source of VFD series Drives via MODBUS communication.

Refer to the following table for the above settings when connecting to VFD series Drives:

Accessing parameters via PKW area

In cyclical data, PD-01 can provide request and response (read / write) message to

access the parameters of VFD series Drives. Due to the request and response

mechanism, the master must send the request until it receives a corresponding

response.

Parameter value (PWE) 3rd and 4th word

All parameters in VFD series Drives are 16-bit. A 16-bit parameter value is transferred

in PWE2 (4th word). PWE1 (3rd word) must be set to 0 on the PROFIBUS-DP master

in this case.

PD-01 PROFIBUS-DP Module

Examples for PKW mechanism

Example 1: Read data of parameter P0003

To read value of P0003, set the request ID to 1 (request parameter value - word).

Because P0003 is less than 2000, the Para Page Select is 0, thus, the data sequence

are as follows:

Master ꢂPD-01 : 1003 0000 0000 0000

0000

1770

Word 3 (PWE1) 0000

Word 4 (PWE2) 0000

PD-01 responds the value of P0003. All parameters in VFD series Drives are 16-bit

value, so the value is transferred in PWE2 (4th word). The value of P0003 is 0x1770

(6000 decimal), in VFD-M series Drives, it is “Maximum Output Frequency”.

Example 2: Read command frequency in VFD series Drives (0x2102)

To read value of command frequency, set the request ID to1, we should set the Para

Page Select because the parameter address is greater than 2000. The address

0x2102 is 8450 in decimal, if set Page Select to 4, then the Basic PNU is 8450 –

4*2000 = 450 (0x1c2), thus, the data sequence are as follows:

Example 3: Write data 2 to parameter P0804

To write data to P0804, request ID is set to 2 (Modify parameter value - word), Para

Page Select should be set because the parameter address is greater than 2000. The

address of P0804 is 0x0804, which is 2052 in decimal, if set Page Select to 1 (bit 15

of IND is 1), then the Basic PNU is 2052 – 1*2000 = 052 (0x34), thus, the data

sequence are as follows:

Master ꢂPD-01 : 2034800000000002

NOTE:

VFD series Drives will write the data to EEPROM. When using PKW to change the

value of parameter, the data will be written to EEPROM directly. However, if this

action is too often, the EEPROM will have no capability of directly saving data.

So please pay close attention on it.

Example 4: Read diagnostic data

User can use the special address to read the current diagnostic data. Please refer to

Section 6.2 for details. The diagnostic address starts from 0x7500 to 0x7504 (5

words). To read diagnostic data in these addresses, request ID is set to 1, Para Page

Select should be set because the parameter address is greater than 2000. The

address 0x7500, which is 29952 in decimal, if set Page Select to 14, then the Basic

PNU is 29952-14*2000=1952(0x7A0), thus, the data sequence are as follows:

Master - > PD-01 : 17A0700000000000

PD-01 - > Master : 17A0700000000300

read data from 0x7500

If PD-01 returns the data 0x0300, it indicates that Scan port is disconnected. Please

refer to Section 6.2 for details.

Example 5: Access error

If take any action using PKW to access parameter in AC Drives and it fails, PD-01 will

response error information. Suppose that Master send data sequence is 202D 8000

0000 0002, if VFD series Drives does not find this address (0x07FD), it will respond

the data sequence 702D 8000 0000 0000, response ID is 7 which means cannot

process request (with error number), and error number is 0 (Illegal Parameter

Number).

Response time about PD-01

The update time via PROFIBUS connection can be divided in 3 parts:

ꢁ T1: Communication time in transmit data from the master to PD-01, and

ꢁ T2: Wait processing in data buffer of PD-01, and

ꢁ T3: Communication time in transmit data from PD-01 to VFD Drives.

Timer

Data Buffer

PD-01 PROFIBUS-DP Module

T1 depends on the actual transmission speed and the type of master in use.

T2 depends on the internal timer of PD-01. Data is transmitted to VFD series Drives per

70ms triggered by a timer. User cannot change the time-out interval.

T3 depends on the Modbus communication between PD-01 and VFD series Drives.

So the update time is,

Max update time = T1 + T2 (70ms) + T3

In fact, the actual update time is less than the Max update time. If the timer time-out

when the data arrive PD-01, PD-01 will save the data to data buffer, and transmit the data

to VFD series Drives immediately.

Chapter 5 User Parameters Setting in GSD file

GSD file

A GSD file is a text file used to identify PROFIBUS-DP device (Master or Slave), which

contains the necessary data for the configuration of DP slaves within a standard DP master.

Typical information in a GSD file are Vendor information, Baud rates supported, Timing

information, Options/features supported and Available I/O signals. The GSD file is the

fundamental building block for the master parameter record.

User parameters in GSD file

The user parameters in GSD file are used for the configuration of the PROFIBUS network.

The description of the user parameters are shown in the following table:

Item

Name

Data Input 1

Type

UINT

Description

Default

0x2000

This is a MODBUS address. The 1st word in

PZD of cyclic output data will be sent to this

address.

Data Input 2

UINT

0x2001

This is a MODBUS address. The 2nd word in

PZD of cyclic output data will be sent to this

address.

PD-01 PROFIBUS-DP Module

Name

Data Input 3

Type

Description

Default

0x0000

UINT

This is a MODBUS address. The 3rd word in

PZD of cyclic output data will be sent to this

address if select Module = "4 PKW, 4 PZD".

This is a MODBUS address. The 4th word in

PZD of cyclic output data will be sent to this

address if select Module = "4 PKW, 4 PZD".

This is a MODBUS address. PD-01 will

monitor this address, and copy the return

data to the 1st word in PZD of cyclic input

data.

Data Input 4

0x0000

0x2101

Data Output 1

Data Output 2

Data Output 3

Data Output 4

d_state

UINT

0x2102

0x2103

0x2104

This is a MODBUS address. PD-01 will

monitor this address, and copy the return

data to the 2nd word in PZD of cyclic input

data.

This is a MODBUS address. PD-01 will

monitor this address, and copy the return

data to the 3rd word in PZD of cyclic input

data if select Module = "4 PKW, 4 PZD".

This is a MODBUS address. PD-01 will

monitor this address, and copy the return

data to the 4th word in PZD of cyclic input

data if select Module = "4 PKW, 4 PZD".

This is a flag. If address in Data Output 1 ~

Data Output 4 is continuous, set it to 1, and

set the others to 0.

This is a length, and unit is word. It specifies

the length of PD-01 to process data in PZD, if

user select the Module = "4 PKW, 4 PZD", but

din_len is 3, PD-01 will process 3 word and

ignore the 4th word.

UINT

0x0001

0x0002

10 din_len

11 dout_len

UINT

0x0002

0x0001

This is a length, and unit is word. It specifies

the length of PD-01 to monitor data from AC

Drive, if user select Module = "4 PKW, 4

PZD", but dout_len is 3, PD-01 will monitor 3

word and ignore the 4th address.

This variable indicates that the PD-01 will

take action when communication with

Profibus network is lost, the value can be

assigned as follows:

12 LossDPComTreat UINT

00 – Ignore event and continue;

01 – Stop according to Pr “Stop Method” in

VFD series Drives.

PD-01 PROFIBUS-DP Module

Item

Name

Type

Description

Default

13 LossSPComTreat UINT

0x0000

This variable indicates that the PD-01 will

take action when the SP communication

(SCANport communication) is lost, the value

can be assigned as follows:

00 – Stop data exchange and report fault;

01 – Continue data exchange and report

alarm;

02 – Ignore and continue data exchange.

If the address in Data Output 1 ~ Data Output 4 is continuous, then set d_state to 1, PD-01

will get starting address from Data Output 1. The next data will be got from the address next

to the starting address, and the reading length is determined by dout_len. If the MODBUS

address for reading is discontinuous, please set d_state to 0, PD-01 will also get starting

address from Data Output 1, but the difference is the other data will be got from the address

saved in Data Output 2, Data Output 3 and Data Output 4 in order.

Example, if

Data Output 1

Data Output 2

Data Output 3

Data Output 4

= 0x2100;

= 0x2101;

= 0x2102;

= 0x2103;

dout_len

= 0x0003;

The MODBUS address in Data Output 1~Data Output 4 is continuous, so you can set the

d_state to 1, then PD-01 will monitor the address starting from Data Output 1, and monitor 3

words from VFD series Drives one time. When the dout_len is 3, PD-01 will ignore the

address in Data Output 4. If d_state is set to 0, PD-01 will read data from the address in Data

Output 1, and read data from the address in Data Output 2, and so forth.

PD-01 PROFIBUS-DP Module

Edit the user parameters in S7 Step hardware configuration tools shown below:

NOTE:

Please do not set d_state to 1 when the address in Data Output 1 ~ Data Output 4 is

non-continuous to avoid Parameterization error and IO disconnect. The PD-01 just check the

address starting from Data Output 1 to Data Output [dout_len-1], in other words, if the

address in Data Output 1 ~ Data Output 3 is continuous, but the address in Data Output 4 is

not, and dout_len is 0x0003, then the check still can pass.

Be sure to set other value and energize PD-01 again.

Troubleshooting via diagnostic data

PD-01 provides 16 bytes diagnostic data when the alarm occurs and when user parameter

setting “LossSPComTreat” is set to “Continue data exchange and report alarm”. It includes 6

bytes standard diagnostic data and 10 bytes device related diagnostic data. The following

table shows the meanings of the 16 bytes:

Byte 1-6

Byte 7

Byte 8

Byte 9

Byte 10

Byte 7 indicates the length of device related diagnostic data including itself, so if byte 7 is 10

(0Ahex), it indicate device related to diagnostic data have 10 bytes (including byte 7).

Byte 8 indicates the SP communication status when the alarm occurs, and the valid value

should be as follows:

PD-01 PROFIBUS-DP Module

00 – Normal

01 – CRC check failure

02 – VFD series Drive returns error code

03 – Communication is time out and disconnected

Byte 9 indicates the error code when byte 8 is 02 (VFD series Drive returns error code). Refer

to the Section 6.3 for the meanings of invalid code.

Other word, user can get the diagnostic data via PZD area any time. PD-01 provides some

special MODBUS addresses to indicate the diagnostic status, the address assignments are

as following:

0x7500

User can get these data through “Data Output 1”, or 2, or 3, or 4 in user parameters. For

example, if set the “Data Output 1” to 0x7500 means get the diagnostic data from 0x7500,

and get the return data from address 0x7500 in 1^stword of PZD area.

NOTE:

These special addresses are read-only, it will fail if user tries to write data to it.

Troubleshooting via error codes

If there is a communication error detected between PD-01 and VFD series Drives, the error

code will be displayed on the digital keypad of VFD series Drives.

VFD series Drives can process the message from PD-01 if the communication setting is valid.

But if the command of message is invalid, the VFD series Drives will respond a report

message that has error codes listed in table below, to PD-01.
