Chapter 1: Features and Functions

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

Number of linkage pointsLinkage method

Relay link 2048 (256 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.

Chapter 2: Safety Precautions

2-1 Installation

Do not install or store the JW-21MN in the following conditions.

- 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

Communication cables should be laid from the master station to the slave station one by one. Multiple wiring from one point or wiring without terminators may cause communication errors.

Joint using a connector

Arrange total cable length within 1 km.

Arrange branch cable line from a trunk within 400 mm.

Prior to any electric welding around the JW-21MN, take out the coaxial cable from the JW-21MN. While the coaxial cable is connected to the JW-21MN, any electric welding nearby the JW-21MN will cause the welding current to enter the JW-21MN and may damage part of its circuit pattern.

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 JW21MN, 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.

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

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 JW21MN using saddles etc.

(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.

(3) Connection to the JW-21MN

The connector to the JW-21MN should be turned right to secure locking, not merely inserted.

(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.

(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).

R45 or larger

- 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.

7-3

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 . Start winding cut tapes from and as well.

(2) Straight connector

To wind the self-adhesive tape, cut the tape at about 15 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

1 The recommended connector types are used.

2 The connectors are securely locked.

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

4 The recommended coaxial cable type is used.

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

6Noheavy 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.)

8 Length oh branch lines is shorter than 400mm.

9 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.

7-7 Wiring method for adding a communication station

(1) Branching method

When branching a line for an additional station, be sure to branch from the trunk using a T connector. Never branch from a branch line.

(3) Notes

When adding a communication station, follow the items below.

No.

Branch from the trunk cable.

Don’t use the same station number

twice. Check the termination resistance

switch. Provide extra length for the

expansion cable. Do not exceed the 1 km limit for total

length of the cable. Change the layout drawing for

installation.

Do not overlap with any PC’s

communication area.

Set the parameter memory of the master station and that of the newly

added station.

Item Reason

Another branch line from a branch line may not give appropriate communication by reflection wave. The use of the same station number twice may cause communication errors. When the newly added station becomes a termination of the circuit, change the setting of the LT switch.

Have enough cable length in order to provide easy wiring.

Longer wiring may cause communication error by signal attenuation.

Maintain the added work data for future maintenance use.

When the communication area or the flag area of the added station overlaps with other addresses in use, communication errors may occur. Without setting the parameter memory of the master station and that of the slave station, the added station cannot communicate.

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/ JW20H/JW30H).

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.

- Master station Data link (Standard function)

- Slave station Data link (Standard function) Data link (Save memory function)

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.

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.

- 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.

Slave station "n" (JW-21MN: Set to save memory function)

9-2 Required transmission time and communication delay time

[1] Required transmission time

This is the time required for the master station to complete communication with all stations, and is determined by the number of connected stations with and the number of data items to transmit.

Transmission T operation cycle = + 2.5 × P + α + 16 (ms)

N:Total number of link points (value to be calculated by relay link bytes and register link bytes

8 points).

P:Number of connected stations (master + slave)

136 : 136 bits are used for station address and error check data on the communication format.

1250 : Transmission rate: 1.25M bits per second

2.5 : Inter-station wait time plus processing time to move to next station (unit : ms) α : Communication recovery operation time

• When an error occurs at any station, the master station periodically treats the error. α = 3.5 × number of error stations ms

16 : Time to maintain token bus. It can enter at random intervals.

[Example] In the case of two connected stations and 8 bytes of link points,

N + 136 × P

1250

PC operation cycle

Master station (PC00)

Slave station (PC01)

Note: Data exchange time between a PC and the JW-21MN can be obtained by the following

Transmission T operation cycle ＝

8 bytes×8 points×2 stations + 136×2 stations

1250

+ 2.5 × 2 stations + 16 = 21.32 ms

9-3 Expansion of network

The JW-21MN can transmit data between 64 stations at maximum. If more than 64 stations are required for data link, you can add communication stations with the procedure below.

[1] Multiple installation of the JW-21MN

Mounting more than one JW-21MN on the basic rack panel of the JW20/JW20H/JW30H can increase the number of stations.

[In the case of mounting 4 sets of JW-21MN]

Remarks

-When installing multiple number of modules on a single PC, make them allocated so that relay link area, register link area, and flag area may not overlap with each other.

- When installing multiple number of modules on a single PC, pay attention to the total communication data volume and the number of bytes available for communication area.

- Though more than one JW-21MN can be mounted on single basic rack panel, they cannot directly communicate with other stations beyond one network.

Chapter: 10 Description for Computer Link Operation

When connected to a host computer with a network module that is compatible with the ME-NET specifications, the JW-21MN can transfer data.

10-1 Computer link function

The host computer communicates with each station number one by one. On the computer link, the host computer can communicate with any required station regardless of whether it is the master or slave station.

(1) The host computer instructs station number/communication contents/memory address/data etc. of

the communicating station as a "command."

(2) The "command" receiving station processes this data and returns the result as "response."

（System example）

Master station (00) Slave station 01(8)

Slave station 02(8) Slave station 03(8)

Command

Response

In order to use the computer link function above, the host computer needs program application software. For programming this software, see the instruction manual attached with the network module.

Computer link commands of the ME-NET can be roughly classified into basic commands and optional commands.

Host computer

[1] Basic commands

Commands mainly used with PCs. These commands are the functions used to read and write relays and registers. The JW-21MN supports all of the basic commands (for both the 47 and 57 family). See the next page.

Reference

The 47 and 57 family: ME-NET computer link commands are divided into the 47 and 57 families of

commands, which use different communication formats. However, you do not need to be concerned about the differences in these families when using the computer link function.

[2] Optional commands

Commands other than the basic commands. These are individual commands specific to each device.

See page 10-3.

(Rear side)

Reference Need for the termination resistance

When a termination resistance is not provided at a communication circuit end, the end of the circuit generates reflection waves. These reflection waves collide with sending signals and abnormal communication may occur. The termination resistance prevents the occurrence of these reflection waves. On the other hand, when an intermediate station has its termination resistance switch turned "ON," this station causes reflection and attenuates signals and causes abnormal communication.

(5) Shield ground switch (LG)

For communication lines, use a coaxial cable. As coaxial cable is an unbalanced circuit, ground its shield by turning "ON" the shield ground switch.

Remarks

-Make sure to provide a class-3 grounding for the GND terminal of the power supply module. Without grounding the power supply module, the JW-21MN cannot become conductive with the ground after turning "ON" the shield ground switch. (See page 7-2.)

- Prior to any electric welding around the JW-21MN, take out the coaxial cable from the JW-21MN While the coaxial cable is connected to the JW-21MN, any electric welding nearby the JW-21MN will cause the welding current to the JW-21MN and may damage part of its circuit pattern.

[1] Setting contents

When the JW-21MN is used as a master station, set the following items for parameters. When the JW-21MN is used as a slave station, setting contents of the parameter address 004004 to 004377(8) and 004404 to 004777(8) may vary with the data link setting condition as a slave station (standard function/save memory function).

[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.

Measure

- 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.

12-6

(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)

76543210
