[Design Precautions]

WARNING" and "! CAUTION".

CAUTION" may lead to

WARNING

• For the operating status of each station after a communication failure, refer to Section 8.2.6 in this manual. Failure to do so may result in an accident due to an incorrect output or malfunction.

• When changing data of a running programmable controller from a peripheral connected to the CPU module or from an external device such as a personal computer connected to an intelligent function module, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other controls to a running programmable controller (such as program modification or operating status change), read relevant manuals carefully and ensure the safety before the operation. Especially, in the case of a control from an external device to a remote programmable controller, immediate action cannot be taken for a problem on the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

[Design Precautions]

WARNING

• Do not write any data to the "system area" of the buffer memory in each intelligent function

module. Also, do not turn on any "use prohibited" signal that is output from the CPU module to the intelligent function module. Writing data to the "system area" or outputting a "use prohibited" signal may cause malfunction of the programmable controller system.

• When setting auto refresh parameters, specify "Y" for the remote output RY refresh devices.

Specifying any other than "Y" (for example, M or L) will hold the previous device status in the case of a CPU stop. For how to stop a data link, refer to Section 8.3.8.

• Disconnection of a CC-Link dedicated cable may make the line condition unstable, causing

communication errors on multiple stations on the network. Configure an interlock circuit in the program so that the system will operate safely even if these communication errors occur on multiple stations. Failure to do so may result in an accident due to an incorrect output or malfunction.

[Design Precautions]

CAUTION

• Do not install the control lines or communication cables together with the main circuit lines or

power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.

[Installation Precautions]

WARNING

• Shut off the external power supply for the system in all phases before mounting or removing the module. Failure to do so may result in electric shock or cause the module to fail or malfunction.

A - 2 A - 2

• Do not directly touch any conductive part and electronic components of the module. Doing so can cause malfunction or failure of the module.

[Wiring Precautions]

WARNING

• Shut off the external power supply for the system in all phases before wiring. Failure to do so may result in electric shock or cause the module to fail or malfunction.

• After installation and wiring, attach the included terminal cover to the product before turning it on for operation. Failure to do so may result in electric shock.

[Wiring Precautions]

CAUTION

• Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when a screw on the terminal block comes loose, resulting in failure.

• Do not install the control lines or communication cables together with the main circuit lines or power cables. Failure to do so may result in malfunction due to noise.

• Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or malfunction due to poor contact.

• Tighten the terminal block screw within the specified torque range. Undertightening can cause short circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or malfunction.

• When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable with connector, hold the connector part of the cable. For the cable connected to the terminal block, loosen the terminal block screws. Pulling the cable connected to the module may result in malfunction and damage to the module or cable.

A - 3 A - 3

[Wiring Precautions]

CAUTION

• Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.

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

• For the CC-Link system, use dedicated cables that are specified by the manufacturer. If any other cable is used, performance of the CC-Link system is not guaranteed. Also, the maximum overall cable length and the station-to-station cable length must meet those specified in Chapter 3. If not, normal data communication is not guaranteed.

[Startup and Maintenance Precautions]

WARNING

• Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.

• Shut off the external power supply for the system in all phases before cleaning the module or retightening the screws on the terminal block. Failure to do so may result in electric shock.

[Startup and Maintenance Precautions]

CAUTION

• Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.

• Shut off the external power supply for the system in all phases before connecting or disconnecting the module. Failure to do so may cause the module to fail or malfunction.

• Tighten the screws on the terminal block within the specified torque range. Undertightening can cause drop of parts or wires, short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

• After the first use of the module, the number of module connections/disconnections is limited to 50 times. Exceeding the limit (in accordance with IEC 61131-2) may cause malfunction.

1 CC-Link SYSTEM

1.1 About CC-Link System

The CC-Link system is a system that connects distributed modules such as I/O modules, intelligent function modules, and special function modules using dedicated cables so that these modules can be controlled by a programmable controller CPU.

(1) By connecting each module separately to equipment such as a conveyor line or a

machine, the number of wires can be reduced in the entire system.

(2) Each module’s on/off information of input/output and numeric data can easily be

sent and received at high-speed.

(3) By connecting multiple programmable controller CPUs, a simple distributed

system can be configured.

(4) Since various devices from Mitsubishi's partner manufacturers can be connected,

the system can provide flexible solutions depending on the user’s requirements.

(2) Remote device station communication

Programmable controller CPU

The remote device station is a remote station that handles bit and word data. Signals for handshaking with the remote device station (initial request, error occurred flag, etc.) are communicated using the remote input RX and remote output RY. The setting data to the remote device station are communicated using remote registers RWw and RWr (refer to Section 8.1.2).

(3) Local station communication

The local station is a station having a programmable controller CPU and the ability to communicate with the master and other local stations. Communication between a master station and a local station uses two types of transmission methods: cyclic transmission and transient transmission (refer to Section 8.1.3).

(a) Cyclic transmission

Data communication between programmable controller CPUs can be performed in N:N mode using bit data (remote input RX and remote output RY) and word data (remote registers RWw and RWr).

(4) Intelligent device station communication

The intelligent device station is a station that can handle bit and word data. Communication between a master station and an intelligent device station uses two types of transmission methods: cyclic transmission and transient transmission (refer to Section 8.1.4).

(a) Cyclic transmission

Signals for handshaking with the intelligent device station (positioning start, positioning complete, etc.) are communicated using the remote input RX and remote output RY. Numeric data (positioning start number, present feed value, etc.) is communicated using remote registers RWw and RWr.
