SAFETY PRECAUTIONS

(Read these precautions before using.)

Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The instructions given in this manual are concerned with this product only. For the safety instructions of the programmable controller system, please read the user's manual of the CPU module used. In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".

DANGER

CAUTION

Note that the CAUTION level may lead to a serious consequence according to the circumstances. Always follow the instructions of both levels because they are important to personal safety.

Please save this manual to make it accessible when required and always forward it to the end user.

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

[DESIGN PRECAUTIONS]

DANGER

For each station's operating status in the case of a communication error in the network, refer to this manual. A malfunction due to a communication error may result in an accident.

To control a running programmable controller (data modification) by connecting GX Developer to a CPU module or connecting a personal computer to an intelligent function module, create an interlock circuit on the sequence program so that the entire system will function safely all the time. Also, before performing any other controls (e.g. program modification, operating status change (status control)) to the programmable controller, read the manual carefully and ensure the safety. Especially, in the case of controlling a remotely-located programmable controller from an external device, a programmable controller side problem could not be resolved immediately due to data communication failure. To prevent this, establish corrective procedures for communication failure between the external device and the programmable controller CPU, as well as creating an interlock circuit on the program.

Laser diodes are used in the optical transceivers of the CC-Link IE controller network. The class of these laser diodes is Class 1.

[DESIGN PRECAUTIONS]

CAUTION

Do not install the control lines and/or communication cables together with the main circuit or power cables, and also do not bring them close to each other. Keep a distance of 100mm (3.94 inch) or more between them. Failure to do so may cause a malfunction due to noise.

[INSTALLATION PRECAUTIONS]

CAUTION

Use the programmable controller in the environment conditions given in the general specifications of the User's Manual for the CPU module used. Failure to do so may cause an electric shock, fire, malfunction, or damage to or deterioration of the product.

While pressing the installation lever located at the bottom of the module, insert the module fixing projection into the fixing hole in the base unit to mount the module. Incorrect module mounting may cause a malfunction, failure, or drop of the module. In an environment of frequent vibrations, secure the module with the screw. The screw must be tightened within the specified torque range. If the screw is too loose, it may cause a drop, short circuit, or malfunction. Excessive tightening may damage the screw and/or the module, resulting in a drop, short circuit or malfunction.

Be sure to shut off all phases of the external power supply used by the system before mounting or removing the module. Failure to do so may damage the module.

Do not directly touch any conductive part or electronic component of the module. Doing so may cause a malfunction or failure of the module.

[WIRING PRECAUTIONS]

DANGER

Be sure to shut off all phases of the external power supply before installation or wiring. Failure to do so may result in an electric shock or damage to the product.

A - 2

[WIRING PRECAUTIONS]

CAUTION

Always ground the FG terminal to the protective ground conductor. Failure to do so may cause a malfunction.

Verify the rated voltage and pin-out, and connect the external power supply cable properly. Connecting a power supply with a different voltage rating or faulty wiring may cause a fire or failure.

Terminal screws must be tightened with the specified torque. If a screw is loose, it may cause a short circuit, fire or malfunction.

Be careful to prevent foreign matter such as dust or wire chips from entering the module. Failure to do so may cause a fire, failure or malfunction.

Be sure to place the communication cables or power cables in a duct or clamp them. If not, dangling cables may swing or inadvertently be pulled, resulting in damage to the module or cables, or malfunctions due to poor cable connection.

When disconnecting a communication cable or a power cable from the module, do not pull the cable part. For a cable with connectors, hold the connector by hand and disconnect it from the module. For a cable connected to a terminal block, loosen the terminal block screws and disconnect the cable from the module. Pulling a cable that is still connected to the module may cause a malfunction or damage the module and/or the cable.

A protective film is attached to the module top to prevent foreign matter such as wire chips from entering the module during wiring. Do not remove the film during wiring. Be sure to remove it for heat dissipation before system operation.

[STARTUP/MAINTENANCE PRECAUTIONS]

CAUTION

When performing online operations (especially, program modification, forced output or operating status change) by accessing a running CPU on another station from GX Developer via CC-Link IE controller network, read the manual carefully and ensure the safety. Improper operation will cause mechanical damage or accidents.

Do not disassemble or remodel each of the modules. Doing so may cause failure, malfunctions, personal injuries and/or a fire.

A - 3

Page 6

[STARTUP/MAINTENANCE PRECAUTIONS]

CAUTION

When using a wireless communication device such as a mobile phone, keep a distance of 25cm (9.85 inch) or more from the programmable controller in all directions. Failure to do so may cause malfunctions.

Be sure to shut off all phases of the external power supply used by the system before mounting or removing the module. Not doing so may result in a failure or malfunction of the module.

Do not touch terminals during power-on. Doing so may cause malfunctions.

Be sure to shut off all phases of the external power supply used by the system before cleaning or retightening the terminal screw or module mounting screw. Not doing so may result in a failure or malfunction of the module. If the screw is too loose, it may cause a drop, short circuit or malfunction. Excessive tightening may cause damage to the screw and/or module, resulting in a drop, short circuit or malfunction.

Before handling the module, touch a grounded metal object to discharge the static electricity from the human body. Not doing so may cause a failure or malfunction of the module.

Do not install/remove the module to/from the base unit more than 50 times after the first use of the product. (IEC 61131-2 compliant) Failure to do so may cause malfunction.

[DISPOSAL PRECAUTIONS]

CAUTION

When disposing of this product, treat it as industrial waste.

OVERVIEW

CHAPTER1 OVERVIEW

This manual provides information on the specifications, functions, preoperational procedure, programming and troubleshooting of the QJ71GP21-SX and QJ71GP21S-SX CC-Link IE controller network modules (hereinafter referred to as CC-Link IE controller network module). When applying a program example introduced in this manual to the actual system, make sure to examine the applicability and confirm that it will not cause system control problems.

The CC-Link IE controller network module allows connection of MELSEC-Q series programmable controllers to the CC-Link IE controller network, realizing high-speed and large-volume data communications between the controllers in the network.

POINT

(1) The existing MELSECNET/G network module has been integrated into the

CC-Link IE controller network module.

(2) The CC-Link IE controller network is an improved system that has a higher

processing speed and a larger data capacity than the MELSECNET/H network system (PLC to PLC network). For comparisons between CC-Link IE controller network and MELSECNET/H, refer to the following.

Appendix 4 Comparison between CC-Link IE controller network and

MELSECNET/H

(3) One network (of the same network No.) cannot contain both CC-Link IE

controller network and MELSECNET/H modules. (Different networks must be used.)

OVERVIEW

(d) Automatic transfer is available between link devices of the CC-Link IE controller

network module and devices of a CPU module. (Link refresh) For the Universal model QCPU, the extended link register (W) is useful for transferring link register (LW) data that exceeds the link register (W) capacity (8K

points).

* 1 Models other than the Universal model QCPU do not have the extended link register (W).

Use a file register instead.

OVERVIEW

(g) Cyclic transmission is available only to any specific stations. (Group cyclic

transmission function) A Universal model QCPU can share cyclic data with stations in the same shared group. This function is useful, for example, when sharing data among all stations that integrates and controls production lines and not sharing the data with stations that controls other machines. Also, receiving cyclic data only from any specific stations can reduce the number of link refresh points, resulting in a shorter link refresh time.

OVERVIEW

(6) Redundant system construction is available. (Compatibility with

redundant CPUs)

(a) System redundancy using CC-Link IE controller network modules can be

designed. By mounting a CC-Link IE controller network module to each of base units with redundant CPUs, a redundant system can be configured. If an error occurs in the control system CPU or CC-Link IE controller network module, the control and standby systems will be switched each other, and the standby system will take over the system control and data link.

(b) System switching request can be issued to the control system CPU.

When the CC-Link IE controller network module of the control system CPU detects a data link error, it can issue a system switching request to the control CPU.

With a link dedicated instruction or from GX Developer, device data can be read from or written to its own system, control/standby system, system A/B of a redundant system, and remote RUN/STOP can be controlled. By specifying the target station's CPU type to Control or Standby system, the target can be fixed even if a system switching occurs.

module from the sequence program.

Assures cyclic data integrity in units of 32 bits or

stations.

Keeps the link scan time constant by making each

station to send the specified number of transient

transmissions within one link scan.

A Universal model QCPU can share cyclic data only

with stations in the same shared group. It does not

receive cyclic data from stations in a different shared

group. Stations without shared group setting will

share cyclic data with all stations.

Used to reserve a station that will be connected to

the network in the future (although the station is not

actually connected at present, it must be included in

the total number of stations for the network.)

Reserved stations are not detected as faulty.

Transfers link device (LB/LW) data of a network

module to another network module at a relay station.

Disables receiving data from other stations and

sending data of its own station in a case such as

debugging. (Transient transmission is not stopped.)

Even if the control station goes down, a normal

station (sub-control station) takes over the control to

continue data link.

Any disconnected cable or faulty station is isolated

from the network, and data link can be continued

among normally operating stations.

When a station disconnected from a network due to

a data link error recovers from the error, the station is

automatically reconnected to the network and

restarts data link.

A cable fault can be detected as a cause of a

communication error.

Incorrect cable connection between OUT and IN can

be detected as a cause of loopback or disconnection

from the network.

Duplication of the control station or station No. can

be detected as a cause of loopback or disconnection

from the network.

The external power can be directly supplied to the

CC-Link IE controller network module with external

power supply function.

The time at which a transient transmission by a link

dedicated instruction failed can be detected, and

network No. and station No. of the station where the

error is detected can be confirmed.

Transient transmission can be performed to another

station even if an error has occurred in the CPU

FUNCTIONS

4.1.6 Cyclic transmission punctuality assurance

This function keeps the link scan time constant by making each station to send the specified number of transient transmissions within one link scan.

POINT

(1) Use this function to eliminate the fluctuation in link scan time, which is caused

by transient transmissions. (Optimum cyclic transmissions are available.) Note that, if the network line status is unreliable, the cyclic transmission punctuality may not be ensured.

(2) To keep the link scan time constant even if the network line status is

unreliable, use the constant link scan function.

Section 4.1.7 Constant link scan

(3) While this function is used to keep the link scan time constant, the

transmission delay time is not kept constant by this function. The transmission delay time is affected by a factor such as a prolonged sequence scan time.

(4) If the punctuality assurance setting is enabled, the link scan time is constant

but longer than the case of no punctuality.

POINT

(1) This function is used to keep the link scan time constant even if the network

line status is unreliable. Note that, if the actual link scan time is longer than the constant link scan time, the operation is performed based on the former.

(2) While this function is used to keep the link scan time constant, the

transmission delay time is not kept constant by this function. The transmission delay time is affected by a factor such as a prolonged sequence scan time.

Remark

(1) Use this function to perform cyclic transmission only with any given stations,

for example, as described below.

• All stations need to share the data of the station controlling production lines.

• Data sharing is not desired between the stations that control different machines.

(2) Since each station receives only the cyclic data from any given stations, the

number of link refresh points can be reduced, resulting in a shorter link refresh time.

4.1.9 Reserved station specification

This function allows reservation of a station that will be connected to the network in the future (although the station is not actually connected at present, it must be included in the total number of stations for the network.). Reserved stations are not detected as faulty stations even though they are not actually connected. Reserved stations are specified by the control station's [Network range assignment] [Supplementary setting].

Section 6.3.5 Reserved station specification

OVERVIEW

When a reserved station actually exists on a network, transient transmissions are executable to the station. In other words, the following are available for the station.

• Checking error details by CC IE Control Network Diagnostics

• Writing parameters from another station in the case of erroneous parameter setting

• Monitoring other stations by GX Developer

• Dedicated instructions

When disconnecting a reserved station from a network, set the mode of the station to "Offline".

target.

• All stations: Executed to all stations in the network specified by [Specify execution

unit].

• Specific group: Executed to the specified group No. in the network specified by

[Specify execution unit].

POINT

(1) The clock time is set up regardless of the ON/OFF status of SM210 (Clock

data set request) of the CPU module. (The ON/OFF status of SM210 does not change after execution of the time setup.)

(2) The set time data are stored in SD210 to SD213 (Clock data) when SM213

(Clock data read request) of the CPU module turns ON.

(3) [Set time] will generate a time error equivalent to the transfer time.

FUNCTIONS

4.2.5 Changing number of transient transmissions

The number of transient transmissions that one station can execute during one link scan can be changed. For how to change the number of transient transmissions, refer to the following.

Section 6.3.6 Supplementary settings

POINT

(1) When a large number is set, if multiple transient requests are made in one link

scan, the link scan time will be increased temporarily. Therefore, do not set a number larger than necessary.

(2) When the fixed link scan time is desired, use the feature of the cyclic

transmission punctuality assurance.

Sub-control station No.2

Normal station No.3

POINT

(1) While the control station status is switched, data link stops for a period of a

data link monitoring time (up to two seconds).

Section 6.3 Network Range Assignment

Data immediately before the stop are held during data link stop.

(2) While data link is stopped, the own station identifies all other stations as

faulty.

(3) Even if cyclic transmission of the control station is stopped by GX Developer,

the control station status is not switched.

Section 4.1.11 Stop/restart of cyclic transmission

(4) The control station status can be switched to a normal station where cyclic

transmission has stopped by GX Developer.
