Chapter 1: Features and Functions

JW-21MN is a ME-NET module for JW20/JW20H/JW30H. Using this module, you can construct an ME-

NET combining various FA equipment such as personal computer and robot.

Using this module, you can easily transmit and receive ON/OFF signals and data with devices that

have a network module which is compatible with the ME-NET specifications.

[When you want to install a JW-21MN in the JW30H, make sure to select one that is compatible with

the JW30H. (See precautions inside the front page of this manual.)]

(1) Data link function

- Send and receive an ON/OFF signal (relay link) and data (register link)

between modules on the ME-NET.

Linkage method

Number of linkage points

Relay link

2048 (256 bytes) in total

2048 bytes in total

* The amount of data that can be transmitted by one station is a maximum of 1024 bytes,

including both relay link and register link.

- In order to use memory effectively, the JW-21MN has a memory save function. When this

function is enabled, it only needs to receive the specifically required data.

(2) Computer link function

- Triggered on commands (instructions) from a host computer which has a network module

compatible with the ME-NET specifications, the JW-21MN starts reading and writing the memory

in the JW20/JW20H/JW30H.

- After an instruction is received from the host computer, the JW-21MN returns a response.

Therefore, the host computer is required to create an application program. For detailed

description of how to transmit instructions and receive responses, see the instruction manual for

the host computer.

(3) This module is available communication up to 64 stations. By using a cable, it can be

extended up to 1 km.

Reference

ME-NET is a communication network to link different brands of devices and equipment with different

models of facility control equipment. It has been developed under the support of Toyota Motor Co.,

Ltd.

- Direct sunlight

- Ambient temperature exceeding the range of 0 to 55 ˚C (Storage temperature : -20 to 70 ˚C)

- The relative humidity exceeding the range of 35 to 90%.

- Sudden temperature changes which may cause condensation.

- Corrosive or inflammable gas

- Vibration or hard jolts

Prior to installing or detaching the JW-21MN, make sure to turn OFF the power supply to the JW20/

JW20H/JW30H (main PC of the system).

All screws must be tightened firmly.

2-2 Wiring

Make sure to use only the recommended types (see page 6-1) for cables, connectors, and

crimping tools. Cable and connector installation and changes must be performed only by specialists

approved by the ME-NET bureau.

When using connectors for branch or joint lines, provide jackets to protect connectors.

(When a connector touches with an external enclosure or the like, a communication error may

occur.)

"T" jacket

(insulation cover)

"L" jacket

(insulation cover)

Do not connect the ground terminal of the power supply module together with other equipment's

ground lines. Make sure to provide class-3 grounding.

When the JW-21MN is used without connecting a class-3 grounding, malfunctions by noise may

occur.

Communication cables should be arranged as far from any high voltage lines and strong power

lines as possible. Do not lay the communication cable parallel or proximate to these lines.

2-1

2-3 Treatment

For ventilation, holes are provided in the cabinet to prevent a temperature rise. Do not block the

ventilation holes. Good ventilation is necessary.

Never allow a liquid such as water and chemical solution and a metallic object like a copper wire

inside the JW-21MN to avoid a possible hazard. Otherwise, it may be a cause of machine trouble.

When a trouble or abnormal condition such as overheat, fume, or smoke is met, stop the operation

immediately, and call your dealer or our service department.

2-4 Static electricity

In extremely dry circumstances, the human body may have excessive static current. This excessive

static current may damage parts in the JW-21MN's PC board. Therefore, prior to accessing the JW-

21MN, touch your hand to a grounded piece of metal to discharge the static current in your body.

2-5 Maintenance

Use a clean, dry cloth when cleaning the JW-21MN. Do not use volatile chemicals such as thinner or

alcohol as it may result in deformation and color fading.

2-6 Allocation of relay number

JW20/JW20H/JW30H which installs JW-21MN are laid out 16 points to the JW-21MN as a relay

number. These 16 points are dummy area which is not used in JW-21MN.

Chapter 7: Wiring Method

7-1 Cable trunk and branch lines

On the illustration of the cable wiring below, a bold line means a trunk and the thin lines branched

from the trunk with a "T" shape are called branch lines.

Branch line

400mm max.

Trunk cable

The length of branch lines branched from the trunk should be within 400 mm.

Branch line

400mm

Trunk cable

Total cable length should be within 1 km.

7-2 Relaying of trunk cables

To relay trunk cables, use the straight joint (ME-JJ-01).

ME-JJ-01

Relaying of trunk cables should be limited to indispensable cases only. Inadvertent relaying of trunk

cables may cause a communication fault such as a weakened signal level due to contact resistance

in the junction connector (straight).

7-3 Cable wiring procedure in control panel

(1) Fixing of the cable

Saddle

In order not to put any force on the cable and the

JW-21MN, fasten the cable to an line nearby input of

a control panel or a "T" branch point to the JW-

21MN using saddles etc.

Saddle

(2) Extra length of cable

Provide an extra length of the cable of 2 to 3 m

inside a control panel for easier processing of the

cable end and easier wiring when changing module

positions.

An extra length of

cable of 2 to 3 m

(3) Connection to the JW-21MN

The connector to the JW-21MN should be turned

right to secure locking, not merely inserted.

Communication cable

(4) Insulation cover

When the connector touches with a high voltage

section or external enclosures, communication

errors may occur. Make sure to install an insulation

cover.

"T" jacket

(insulation cover)

"L" jacket

(insulation cover)

(5) Grounding of power supply module (JW-22PU/31PU)

Make sure to use a class-3 grounding to connect the GND terminal of the power supply module.

- If the power supply module is not grounded, the JW-21MN cannot conduct with the ground after

turning "ON" the shield ground switch.

(6) Bending radius of the signal cable should be less than 45 mm (outside).

- Specification of the cable manufacturer is that bending radius should be 6x of the cable finish

outside diameter (approx. 7.5 mm).

(7) When you install morethan one module of the JW-21MN into one programmable controller, we

recommend to put identification tag on each dable.

(8) Before transport or store the JW-21MN, put a protection cap on the connector of the JW-21MN.

7-4 Waterproof and insulation processing of connectors

In order to prevent water intrusion into the "T" branch connectors and the straight connectors, we

recommend to wind a self-adhesive tape and provide waterproof processing for them. For insulation

purposes, cover these connectors with jackets.

(1) "T" branch connector

To wind a self-adhesive tape, cut the tape at about 10 cm each and start winding from position

Remarks

Prior to adhering the tape, clean the surface of the connectors and stick the adhesive side of

the tape on the connector surface. Wind to lightly spread on the connector surface, and overlap

with the next wrap to half of the tape width. Wind the tape for each wrap evenly so that the

connector metal portion is completely covered with the tape.

Be careful not to excessively stretch the tape.

7-5 Wiring of cables at outside control panels

Do not bundle the coaxial cable (the trunk and branch lines) together with power cables, and

separate from power cables at least by 100 mm. Do not put the coaxial cable into a power line wired

duct. The best way is to put the communication line in an independent duct.

Be careful that the coaxial cable does not receive any load by laying under a heavy weight such as

other cables.

When other cables run in the same duct as the coaxial cable, run the coaxial cable on the top

position.

Do not run the coaxial cable outdoors as it may cause damage to the JW-21MN due to inductive

lightning or atmospheric charge during lightning.

7-6 Check after wiring

Check the items below after completion of wiring.

Check contents

The recommended connector types are used.

The connectors are securely locked.

The connectors are insulated by "T" jacket or "L" jacket.

The recommended coaxial cable type is used.

Curved radius of the coaxial cables are more than 45 mm.

No heavy load is on the coaxial cables.

The coaxial cable is not bundled with a power line cable.

(Away from power line cables more than 100mm.)

Length oh branch lines is shorter than 400mm.

Total length of the cable is less than 1km.

Settings of the termination resistance switch and the shield ground switch are as

per the drawings.

Chapter 8: Memory Address on the ME-NET

The ME-NET employs a system for addressing individual memory banks in all of the connected

equipment by allocating address throughout the ME-NET. Therefore, the top address in any link area

which will contain in the data link parameters and memory addresses used for computer link

instructions must be a valid memory address in the ME-NET.

The relationship between memory addresses in Sharp PCs (JW20/JW20H/JW30H) and those on the

ME-NET are shown below.

8-1 Memory address for data links

The memory addresses(8) on the ME-NET correspond to the file addresses(8) in a Sharp PC (JW20/

Chapter 9: Description for Data Link Operation

The data link function is used to send and receive ON/OFF signals (relay link) and data (register link)

between modules by assigning one module from PCs or FA devices as the master station and other

units as slave stations in the satellite net system. Up to 64 sets of PCs and FA devices can be

connected in the satellite net.

Each station sends data in its sending area cyclically and stores data received from other stations in its

receiving area. For the JW-21MN to execute automatically these sending and receiving procedures, a

special program for communications is required.

When the JW-21MN is assigned as a slave station, it has the standard function and save memory

function for data link, but the data contents for receiving from other stations is different between these

two functions. (When the JW-21MN is used as a master station, only the standard function is available.)

[When all of a master station and slave stations are JW-21MN]

- Master station

- Slave station

Data link (Standard function)

Data link (Save memory function)

Receiving data of all of the relay link area and

all of the register link area of all the stations.

｝

In order to effectively use the

memory, unify a partial data area or

sending/receiving address (program)

of slave stations.

For the standard function and the save memory function of the JW-21MN, see page 15-2.

9-1 Communication method

[1] Data link (Standard function)

Each station cyclically sends and receives ON/OFF signals and data of the relay link area and register

link area set to a master station parameter.

(1) Relay link

Mainly used for sending and receiving ON/OFF information

[Example] In the case of sending 1-byte data from a master station and slave stations 01 and 02.

- The link relay of the receiving station must be programmed as input signal by the PC program-

ming. Also, it may be used as source (S) side of application instruction.

- The sending and receiving data correspond in bits of one point unit.

- The register link of the sending station may be used as D (Destination) side of the application

instruction of the PC program.

- The register link of the receiving station may be used as S (Source) side of the application

instruction of the PC program.

[2] Data link (Save memory function)

The save memory function is to provide a part of the data link area in the slave station data memory as

a receiving area. A slave station can receive only the required area by relay link/register link so that the

slave stations can save on use of the memory area.

As this function can unify the receiving area address and the sending area address of each slave

station, the same program can be used for each slave station. Mixed allocation of the addresses with

the data link (standard function) is also possible.

[3] Setting range of relay link area, register link area, and flag area

For setting the top address of the master stations relay link, register link, and flag area, use the file

address(8) allocated throughout the memory area and set the number of sending bytes of the relay link

and register link area within the setting range shown below. Flag areas are allocated by 24 bytes from

each top address.

When a slave station is a JW-21MN and it is set to data link (the standard function), set the top address

and the number of sending bytes of the slave station's relay link and register link area within the setting

range shown below.

When a slave station is a JW-21MN and it is set to data link (the save memory function), the relay link

and register link area of the slave station are determined by the setting value of the JW-21MN module

No. switch (page 11-2) as shown below.

- In some cases, error code 23^(H)or 2A(H) is stored when inputting power. This is not an error.

- Error code 60^(H), 6E(H), C1 to FF(H) are special error codes unique to the JW-21MN.

(1) System memory #170 to 177 (option module error code)

The error code stored in the system memory #170 is shifted to #170 to #177 one after the other as

new errors occur. Thus, the system memory can store up to 8 errors. When the PC is operating by

RAM, these error codes do not disappear even after turning OFF the power.

The contents of system memory #170 to #177 are kept storing after the JW-21MN recovers from the

error.

(2) System memory #160 to 167 (self diagnosis error code)

When any of errors "01(H)" to "18(H)" occurs among the error codes listed on the previous page, the

JW-21MN stores error code "53(H)" (optional error) in the system memory #160. It does not store any

error code in system memory #170.

(3) System memory #150 (monitor error switch number)

When you monitor the system memory #050 at the occurrence of error code "53(H)," you can check

the module No. switch setting value of the error causing option module with a bit pattern. (At normal:

OFF, at error: ON)

If there are errors in the station number and the mode switch, change the setting with the power

OFF, and then turn ON the power.

[Check items of cables and connectors]

①No looseness or removal of connectors (turn the connector right until it completely locks).

②Connectors are appropriately fixed on the cables (When any faults such as extrusion of pins or

connector being easily removed by pulling, reinstall these connectors.)

③Wiring conditions are appropriate (See chapters 6 and 7).

④Not too long branch lines (shorter than 400 mm).

⑤Termination resistance are correctly connected.

(Turn "ON" the termination resistance switch of the end stations or install a termination tool.)

(4) When the communication error occurs instantaneously.

Cause may be:

- Noise on the communication line.

- Fault of a communication module.

- Fault of a communication cable.

Check the error's timing.

When the error occurs synchronous with a peripheral industrial robot's operation, noise to the

communication line may be a cause. Consider arrangement of the wiring route.

Identify the error station.

When the error occurs at only the specific station, the cause may be the station or nearby. Check

the following items.

- Setting of the LT (termination resistance) switch.

- Cable (See page 16-6 "Check items of cables and connectors")

- Error code (See page 12-1)

When identification of the cause is difficult.

Condition of the circuit may be unstable. (See page 16 -6 "Check items of cables and connectors")

(5) When the communication error occurs continuously.

Identify the error station.

Specify the error's station using the communication flag etc., and check this station.

- Check the power of the error's station.

- Check the error code of the error's station.

- Check cables near the error's station. (See page 16-6 "Check items of cables and connectors")

When identification of the cause is difficult.

Condition of the whole circuit may be unstable. Check cables and connectors.
