Chapter 1 Outline
Using network module JW-20CM, you can construct a communications system (satellite net) which
can easily send and receive an ON/OFF signal (machine information) and numerical data (production
data) between PCs and a host computer using equipment control.
Using remote I/O slave module JW-20RS, you can construct a remote I/O system as master station for
PC that installed JW-20CM.
PCs which can use JW-20CM and JW-20RS are W70H/100H, JW50/70/100, and JW50H/70H/100H.
Data link/computer link function
This function enables to send and receive ON/OFF signals and numeric data between modules on
a network (satellite net) which is connected PCs and personal computers having network module
ZW-20CM/JW-20CM/JW-22CM, network module ZW-98CM/ZW-20AX, and satellite net board Z335J.
Remote I/O function
If remote I/O slave module ZW-20RS/JW-20RS are mounted on I/O modules located separately,
one PC having a network module JW-20CM can control these slave modules. (Connectable
maximum 63 modules of slave stations.)
· In the remote I/O function, the remote I/O can choose either of synchronous or asynchronous for
sending and receiving data with slave stations.
Synchronous type: Slave station scans input/output operation one time for each operation of
the PC.
Asynchronous type: When PC's operation time is longer than data transfer required time of the
remote I/O, the slave station scans input/output operation one time for each
operation of the PC. When PC's operation time is shorter than the data
transfer required time of the remote I/O, the slave station operate input and
output one time for several operation of the PC.
Remote programming/remote monitor function
By constructing a satellite system using the JW-20CM, you can program and monitor other station’s
PC’s (master station’s PC in case that remote I/O function) on the satellite system using a support
tool.
· These remote programming and remote monitor functions are also available beyond one
hierarchical layer difference (satellite net
satellite net, satellite net
SUMINET-3200).

Chapter 2 Safety Precautions
2-1 Installation
Do not install or store the JW-20CM 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-20CM, make sure to turn OFF the power supply to the PCs.
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.
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-20CM 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-20CM, take out the coaxial cable from the JW-20CM.
While the coaxial cable is connected to the JW-20CM, any electric welding nearby the JW-20CM will
cause the welding current to enter the JW-20CM and may damage part of its circuit pattern.

<Adjustment of blade cutting depth>
Adjust the cutting depth of the blade by turning the
two screws at both ends of the screw holder. Set
the blade position to within 1 mm from the cutting
surface of the blade cassette prior to adjusting the
cutting depth. For the cutting depth adjustment, use
the “blade setting gauge” supplied as an accessory
and match the blade position with the caved position
of the gauge. Then move the cam wheel forward
and secure firmly. Turn right lightly both adjustment
screws at either end of the screw holder for

Put a coaxial cable while remaining approximately 10 mm into
the cable stripper and securely tighten the cable with the middle
finger, ring finger, and little finger of your left hand in order to
hold stable during turning the stripper.
Put your right hand forefinger into the cam wheel and execute
the procedure in order from step 1 below.
Step 1 Press the cam wheel forward 3 times and turn
the stripper in the direction of arrow 2 to 3
times.
Step 2 Press the cam wheel forward 1 time and then
turn the stripper in the direction of arrow a
further 2 to 3 times.
Step 3 Press the cam wheel forward 1 more time and
turn the stripper in the direction of the arrow
another 2 to 3 times.
<Removal of coating, external conductor,
and insulator>
While holding the coaxial cable with your left hand, grip the
cable stripper so that it keeps a right angle against the coaxial
cable, and press out the cable stripper with your left hand’s
thumb.
When the adjustment
of the blade is not
required
If the stripper cannot be removed smoothly,
adjustment of the blade is not appropriate. In this
case slide the cam wheel backward and remove
the coaxial cable. Then adjust the blade.
<Fine adjustment of blade cutting depth>
When the cutting depth is too shallow or too deep, and
damages the external conductor or the internal conductor, turn
the screws on the screw holder and adjust the blade depth a
little.

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).

[1] Fixing of the cable
In order not to put any force on the cable and the
JW-20CM, fasten the cable to an line nearby input
of a control panel or a “T” branch point to the JW20CM 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.
[3] Connection to the JW-20CM
The connector to the JW-20CM 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.

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.

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.
7·4
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-20CM due to inductive
lightning or atmospheric charge during lightning.
7-6 Check after wiring

Item
Branch from the trunk cable.
Don’t use the same station number

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.
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 Remote I/O
8-1
Description of remote I/O
· If remote I/O slave module JW-20RS is installed on I/O modules located separately, one PC (master
station) having a network module JW-20CM can control these I/O modules.
· Connect between a master station JW-20CM and slave station JW-20RS using one coaxial cable. As
the network module JW-20CM and remote I/O slave module JW-20RS control communication, there is
no need any special program for the PC.
· More than one master stations can be mounted on one PC.
· Maximum 63 modules of slave stations can be connected within the cable total extension length 1 km.
· If a JW model PC has a master station, it can connect with stave stations having JW model I/O modules
and slave stations having ZW model I/O modules. However, mixed installation of JW and ZW model
I/O modules on one slave station is not available.
[
If a master station is installed on a ZW model PC, it can connect only with slave stations
having ZW model I/O modules.

Data transfer required time and communication timing
(1) Required time for data transfer
Time required for a master station to communicate with all the slave stations is determined by number
of connected stations and number of points of all slave stations, as well as number of data bytes of
JW model special I/O modules.
T=
(N + 136 x P) x 2
1250
+ 1.4P + 5.3 + 2.5 (P + 1) + α [ms]
N : Total number of data bytes of all the slave station’s I/O model and JW model special I/O
modules (value to be calculated by number of bytes 8 points)
P : Number of slave stations
136 : Use 136 bits for station address on the communication format and error check function.
1250 : Baud rate; 1.25 M bit/sec.
1.4P + 5.3 : Data processing time of the master station
2.5 : Total sequential send processing of the communication stations.
α : Communication time at executing remote program/remote monitor.
Remarks
· If "synchronous" is selected, one scan cycle time of a PC will vary with change of transfer
required time.
· Number of data bytes on the JW model special I/O module is a value set in parameter
address 000600 to 000777(8) on the master station.
8·3
(2) Communication timing
· For communication with slave stations, either of "synchronous" and "asynchronous" can be selected
for operation with the master station PC.
· When "synchronous" is selected, the JW-20CM communicates with synchronize with operation (one
scan) of the master station PC.
· When "asynchronous" is selected, the JW-20CM communicates with slave stations regardless of
operation of the master station PC. Therefore, even if communication of all stave stations is not
completed, the JW-20CM starts data exchange with the master station and PC.

• When a JW-20CM master module is at either
end the communication line, make sure to
set the termination resistance switch "ON."
Turn ON the termination resistance
switches on these two stations.
Reference: Function of the termination resistance switch
If the communication line does not have a termination resistance, the high frequency signal will
be reflected at the ends of the cable. These reflected signals can collide with the original
communication signals, so that some stations will not be able to communicate normally. The
use of termination resistance suppresses reflected signals. If the termination resistance switch
on any of the stations in between the end of the cable is turned ON, the station will generate a
reflection wave signal or attenuate the original signal and may not communicate normally.
· When the trunk line has a branch in it, turn ON the termination resistance at the station on the
trunk cable.

The mode switch is set to “2” at delivery.
Positions "3 to F" will be used only by our service
man. Do not set the switch to these positions.
· If the master station PC is JW model, it can connect to the slave modules having "ZW model I/O
module" and "JW model I/O module" on the same circuit.

Set STA. NO. (station number) switch
· Set "STA. NO" (station number) in octal
notation in sequential numbers from 01 to 77.
Be careful that there is no doubled setting or
lacked number setting. (Number of
connectable slave stations: See page 8·2)
Set LT (termination resistance) switch
• When a JW-20RS slave module is at either
end the communication line, make sure to
set the termination resistance switch "ON."
Turn ON the termination resistance
switches on these two stations.
Reference: Function of the termination resistance switch
If the communication line does not have a termination resistance, the high frequency signal will
be reflected at the ends of the cable. These reflected signals can collide with the original
communication signals, so that some stations will not be able to communicate normally. The
use of termination resistance suppresses reflected signals. If the termination resistance switch
on any of the stations in between the end of the cable is turned ON, the station will generate a
reflection wave signal or attenuate the original signal and may not communicate normally.
· When the trunk line has a branch in it, turn ON the termination resistance at the station on the
trunk cable.

· If you use a terminator (termination resistance made by Toko Denshi: ME-75) at the end of a
signal cable, turn OFF the termination resistance at the station on the end of the cable.

Set LG (shield ground) switch
· For communication lines, use a coaxial cable.
· As coaxial cable is an unbalanced circuit,
ground its shield by turning “ON” the shield
ground switch.

• 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-20CM 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-20CM, take out the coaxial cable from the JW20CM. While the coaxial cable is connected to the JW-20CM, any electric welding nearby the
JW-20CM will cause the welding current to the JW-20CM and may damage part of its circuit
pattern.

[I/O table registration in case of using JW-I/O]
1. In case of not setting dummy I/O
Register I/O table based on the installed I/O module. (Set parameter address 001001(8) = 65(H), the
procedure B in the flow chart.)
However, in case of parameter address of JW-20RS 001002(8) = 00(H) (default setting), the JW-20CM
automatically registers I/O table when the power is input and there is no need to register I/O table.
(Procedure A in the flow chart.)
2. In case of setting dummy I/O
Set number of dummy I/O points for each slot and registers I/O table based on this setting and the
installed I/O module. (Set parameter address 001001(8) = 64(H), procedure C in the flow chart.)
Procedure D in the flow chart is special method to set byte of I/O module for each slot. Normally set

Remarks
• 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-20CM recovers from the
error.

• When any of errors “01(H)” to “18(H)” occurs among the error codes listed on the previous page, the JW20CM stores error code “53(H)” (optional error) in the system memory #160. It does not store any error
code in system memory #170.
• In the case of an option error "53," when you monitor system memory #050, the bit of error option
module switches ON. When more than 1 bit is error, these bits switch ON. The each ON bit becomes
OFF by recovering from the error condition. But the last ON bit does not become OFF even if the error

Description for data link function
· The data link function us used to send and receive ON/OFF signals (relay link: max. 2048 points) and
numerical data (register link : max. 2048 bytes) by PCs or between PC and personal computers connected
in the satellite net system.
· The master station and slave stations are connected using a single coaxial cable. As the JW-20CM
network module can control the data communications, the PC does not need any special programming.
· When the JW-20CM is assigned as a slave station, it has the standard function and memory capacity
save function for data link. But the data contents for receiving from other stations is different between
these two functions. (When the JW-20CM is used as a master station, only the standard function is
available.)
[When all of a master station and slave stations are JW-20CM]
• Master station

[2] Data link (Memory capacity save function)
The memory capacity save 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.

[4] SEND/RECEIVE function
Different from the data link, the SEND/RECEIVE functions are functions which exchange the data of
the required station of the required time between a PC and a personal computer or between PCs.
The SEND function is the function which writes in the data after assigning the station to send data to,
and the RECEIVE function is the function which reads out the data.

• In this instruction, the function is completed after the target station replies. A special program is
not needed in the connected PC station. If the target station is an upper computer, a program is
required for response after decoding the SEND/RECEIVE instructions.
But if the upper computer cannot decode the SEND/RECEIVE instructions, these instructions
can not be used.
• The data route for the SEND/RECEIVE functions between the control module and this module is
called a “channel.” Each module has four channels, CH0 to CH3, and is able to transfer a maximum
of 256 bytes of data. Therefore, four operations of SEND/RECEIVE functions can be executed
simultaneously on a ladder program.

· There are the “instruction system” and the “data memory starting system” as the starting system
in SEND/RECEIVE functions.
You can select the starting system in each channel using a parameter.
· With the "Data memory start system," the JW-20CM can communicate across different hierarchies
of the satellite net. However, this type of communication has the following limitations.
1 JW20/20H cannot be used as relay stations.
2 ZW-98CM/ZW-20AX cannot be used as communication target stations.
3 The maximum amount of data is 256 bytes.

(1) Instruction system
The PC's application instruction F-202/203 (open channel), F-204 (sending instruction), and F-204
(receive instruction) to send and receive data between modules in a network, and from a module in a
network to an upper stream computer is used.
• In this instruction, the function is completed after the target station replies. A special program is
not needed in the connected PC station. If the target station is an upper computer, a program is
required for response after decoding the SEND/RECEIVE instructions.
But if the upper computer cannot decode the SEND/RECEIVE instructions, these instructions
can not be used.
· SEND/RECEIVE functions of instruction system cannot be communicated two hierarchical layer.

Response
Input conditions of F-202/204/205 instructions should keep being ON until finishing execution of
the instruction (when error flag or carry flag turns to ON.)
• If the input condition is turned OFF during execution of the instruction, the instruction ends in an
incomplete condition. Under this condition, next, when this instruction is given, it will come to a
“communication jam,” and the instruction will not be executed. Turn the power OFF and then ON
again for recovery.
Take any measure for the cases below:
• In case that on instantaneous power failure of min. 10ms occurs and the input conditions turn to
OFF.
[Countermeasure] Change the input conditions to a latched relay.
However if you turn OFF and ON the power during execution of the instruction
while the input condition is set to a latched relay, the JW-20CM will come to
the following state.
F-204/205 instruction processing which is being executed is deleted, and
rising edge of input signal can not be detected for the input condition is kept
ON so that this instruction can not be executed.
[Countermeasure] All flags (07354 to 07357) are turned to OFF. Detect them with the timer, and
operate the next instruction after resetting the input conditions.
Note: The SEND/RECEIVE instruction is not allowed to use 10 to 2C(H) as the file numbers for the
communication target station. The data memory start system can use these numbers.

(2) Data memory starting system
The data memory starting system is the system which starts the SEND/RECEIVE functions without
using exclusive instructions. Set the target station number, data memory address, etc. on the
specified data memory (communication information storage area).
You can increase the amount of data to be transferred in one SEND/RECEIVE operation using
multiple connected channels.
For cases using 1 channel alone, maximum 256 bytes
For cases using 2 connected channels, maximum 512 bytes
For cases using 3 connected channels, maximum 768 bytes
For cases using 4 connected channels, maximum 1024 bytes
Set these channel connections on the parameter (address 007700 to 007703(8)). (See page 9·27
and 48)
[Setting the contents in a communication information storage area]
In order to assign a communication information storage area (64 bytes), set the top address on the
parameter (address 007710 to 007713(8)).

Data transfer required time and communication delay
time
(1) Required time for data transfer
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 =
N + 136
P
1250
+ 2.5
P+
+ 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)
: Communication recovery operation time
• When an error occurs at any station, the master station periodically treats the error.
= 3.5
number of error stations ms
16 : Time to maintain token bus. It can enter at random intervals.

Expansion of network
The JW-20CM 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-20CM
Mounting more than one JW-20CM on the optional slot of the basic rack panel can increase the
number of stations.
[In the case of mounting 4 sets of JW-20CM]

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-20CM can be mounted on single basic rack panel, they cannot
directly communicate with other stations beyond one network.

(2) Hierarchical link
When 2 sets of JW-20CM are mounted on the optional slot of the basic rack panel, hierarchical link
communication is possible and can increase the number of stations.

Set LT (termination resistance) switch
• When master module or slave module is at
either end the communication line, make sure
to set the termination resistance switch "ON."
Turn ON the termination resistance
switches on these two stations.
Reference: Function of the termination resistance switch
If the communication line does not have a termination resistance, the high frequency signal will
be reflected at the ends of the cable. These reflected signals can collide with the original
communication signals, so that some stations will not be able to communicate normally. The
use of termination resistance suppresses reflected signals. If the termination resistance switch
on any of the stations in between the end of the cable is turned ON, the station will generate a
reflection wave signal or attenuate the original signal and may not communicate normally.
· When the trunk line has a branch in it, turn ON the termination resistance at the station on the
trunk cable.

• Make sure to provide a class-3 grounding for the GND terminal of the power module. Without

turning “ON” the shield ground switch. (See page 7 · 2.)
• Prior to any electric welding around the JW-20CM, take out the coaxial cable from the JW-20CM.
While the coaxial cable is connected to the JW-20CM, any electric welding nearby the JW-20CM
will cause the welding current to the JW-20CM and may damage part of its circuit pattern.

2. When using connected channels (see page 10·2)
In the SEND/RECEIVE function, the JW-22CM can transfer and receive a maximum of 256
bytes of data for each channel. For the data memory starting system, the amount of
communication data can be increased by connecting channels.
Set the data amount with 8X(H) (X is 0 to 3, determined depending on which channel is used
for the connector.)
When using connected channels, these should be consecutive channels. For example,
channel 0 and 1, or channel 2 and 3 can be connected to each other, but channel 1 and 3 can
not be connected to each other.

· If the JW-20CM does not receive data from a station within the specified time (initial value: 250
ms when fewer than 32 stations are connected, 450 ms when more than 33 stations are connected),
it turns OFF the communication monitor flag corresponding to this station. The specified time can
be changed by entering a different value at parameter address 007771(8) (communication error
detection time). Use the same value for all the stations.
Normally, this value does not need to be changed. Use the modules with the initial value (00(H)).

Remarks
· Writing time to EEPROM is approximately 0.7 sec. When any error is found for parameter
settings, the JW-20CM lights the error code (6F(H)) by the indication lamp.
When error code 6F(H) lights,
Check flag top address
If the master station also lights up with error code 6F(H), check the top address and
number of bytes in the relay link and register link in the master station which corresponds
to the slave station in which the error occurred.
· Written contents into the EEPROM are automatically transferred to the RAM of the JW-20CM
when turning ON the power of the PC. At transferring, the PC checks BCC and compares
BCC check code of the parameter memory address (007776(8)). When an error is found, the
JW-20CM lights the error code (6E(H)) by the indication lamp.
· If "parameter initialization" is selected, the module initializes parameter addresses 004000 to

2. When using connected channels
In the SEND/RECEIVE function, the JW-20CM can send and receive a maximum of 256 bytes
of data for each channel. For the data memory starting system, the amount of communication
data can be increased by connecting channels.
Set the data amount with 8X(H) (X is 0 to 3, determined depending on which channel is used
for the connector.)
When using connected channels, these should be consecutive channels. For example,
channel 0 and 1, or channel 2 and 3 can be connected to each other, but channel 1 and 3 can
not be connected to each other.

• In the initial settings of the data link function, the JW-20CM will not display errors (on the LEDs on
the panel, or in the system memory) even if it detects a communication error in a slave station. In
order to display the error when a slave station communication error is detected, set bit 0(E) at
parameter address 007750(8) to ON. Each bit at addresses 00751 to 007757(8) corresponds to a
slave station. Turn ON the respective bit if required. (See page 13·15.)
With the setting above, the JW-20CM will display errors when a slave station whose corresponding
bit is ON produces a communication error.

• If the JW-20CM does not receive data from a station within the specified time (initial value: 250
ms when fewer than 32 stations are connected, 450 ms when more than 33 stations are connected),
it turns OFF the communication monitor flag corresponding to this station. The specified time can
be changed by entering a different value at parameter address 007771(8) (communication error
detection time). Use the same value for all the stations.
Normally, this value does not need to be changed. Use the modules with the initial value (00(H)).

Remarks
· Writing time to EEPROM is approximately 0.7 sec. When any error is found for parameter
settings, the JW-20CM lights the error code (6F(H)) by the indication lamp. To recover from this
condition.
Treatment when error code 6F(H) appears and COMM is turned OFF.
Check number of top addresses/bytes of master station “relay link” and “register link.”
Check the set value for number of connected stations.
Check the set value for master station flag top address.
Check whether the function is set to “relay register link.”
· Written contents into the EEPROM are automatically written to the RAM of the JW-22CM
when turning ON the power of the PC. At reading, the PC checks BCC and compares BCC
check code of the parameter memory address (007776(8)). When an error is found, the JW20CM lights the error code
(6E(H)) by the indication lamp.
· If "parameter initialization" is selected, the module initializes parameter addresses 004000 to
007776(8).

Remarks
• Error codes “23” and “2A(H)” may occur when applying power. This is not an error.
• To check the communication cable, remove both connectors and short the connector terminals
at one end. Then measure the conductivity using a tester.
• Check the parameter and switch settings for all stations. If the settings are correct, replace

Remarks
• 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-20CM recovers from the
error.

• When any of errors “01(H)” to “18(H)” occurs among the error codes listed on the previous page, the JW20CM stores error code “53(H)” (optional error) in the system memory #160. It does not store any error
code in system memory #170.
• In the case of an option error "53," when you monitor system memory #050, the bit of error option
module switches ON. When more than 1 bit is error, these bits switch ON. The each ON bit becomes
OFF by recovering from the error condition. But the last ON bit does not become OFF even if the error
condition recovers.

(64 stations max., Total length: 1km max.)
· In order to use the computer link function, you must use application software which can send a command
from the host computer and receive a response from the opposite station.
See “Instruction manual of network module ZW-98CM/ZW-20AX etc.” and the like for operation method
on host computer side.
10·1
10-2 Communication method
The host computer communicates with each station number one by one.
The host computer instructs station number/communication contents/memory address/data
etc. of the communicating station as a “command.”
The “command” receiving station processes this data and returns the result as “response.”
System example
