SAFETY PRECAUTIONS

WARNING

CAUTION

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

Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

(Always read these instructions before using this product)

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 precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, please read the User's Manual for the CPU module used.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

Note that the CAUTION level may lead to a serious consequence according to the circumstances. Observe the precautions of both levels because they are important for personal and system safety.

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

[DESIGN PRECAUTIONS]

WARNING

● 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 (special 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.

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.

A - 1

[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.

● Insert the module fixing projection into the module fixing hole in the base unit to mount the module.(For the AnS series module, fix it to the base unit with screws within the specified torque.) Incorrect module mounting may cause a malfunction, failure, or drop of the module.

● 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]

WARNING

● 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.

CAUTION

● Properly solder a connector for coaxial cable. Failure to do so may cause 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 contact.

A - 2

[WIRING PRECAUTIONS]

CAUTION

● When disconnecting a communication cable or power cable, do not pull it by holding the cable part.

To disconnect the cable, hold its connector that is plugged into the module. Loosen screws for a terminal block before disconnecting a cable for connecting terminal block. Pulling the cable part with the cable still connected to the module may damage the module and/or cable, or cause malfunctions due to poor cable contact.

[START-UP AND MAINTENANCE PRECAUTIONS]

CAUTION

● Do not disassemble or remodel each of the modules.

Doing so may cause failure, malfunctions, personal injuries and/or a fire.

● 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 damage the product.

● 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 cause 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.

[DISPOSAL PRECAUTIONS]

CAUTION

● When disposing of the product, treat it as industrial waste.

2) Master station and A/QnA series local station The data is refreshed automatically at either of the following timing.

• Upon completion of link scan

• Only after execution of the END instruction in the sequence program For the AnUCPU, QnACPU, A2US(H)CPU(S1) and Q2AS(H)CPU(S1), refresh ranges can be changed with refresh parameters.

(a) Communication from a master station to a local station

(b) LRDP/LWTP instruction receive processing

By executing the LRDP/LWTP instruction in the sequence program of the master station, data can be read from or written to local station devices (T, C, D, W).

A Q series local station and an A/QnA series local station are different in processing at the time of accepting the LRDP/LWTP instruction.

1) Q series local station

The receive processing is performed to the LRDP/LWTP instruction in a sequence program.

(a) Automatic return function

When a local station disconnected due to a data link error is recovered, the station automatically returns to the network and restarts data link.

(b) Loopback function (Not provided for the MELSECNET/B data link system)

A faulty part such as a disconnected cable or a faulty station is disconnected from the network to continue data link among normally operating stations.

Data of the special relay (for link) and special register (for link) of a local module are refreshed into CPU module devices. With the refreshed devices, the data link status or a faulty part can be checked. Note that the network diagnostics of GX Developer is not available for Q series local stations. Check the data link status or a faulty part in the above-mentioned way.

(d) Self-diagnostic function

The hardware or cable wiring of a local module can be checked.

(4) A program for refresh and a program for receiving LRDP/LWTP

instruction can be created easily with A/QnA to Q conversion support tool (Version 1.02 or later)

A tool to create a program for refreshing link data and a program for receiving LRDP/LWTP instruction is prepared. When using the A/QnA to Q conversion support tool, a new project can be automatically created by inputting the module mounting position or refresh destination specification of link data on the screen. The new project includes a program for refresh and a program for receiving LWTP instruction. For details on the A/QnA to Q conversion support tool, please consult your local Mitsubishi representative. To create a program used for L series by means of the A/QnA to Q conversion support tool, refer to the following:

CHAPTER2 SYSTEM CONFIGURATION

This chapter describes the system configuration of a local module.

2.1 Overall System Configuration

(1) MELSECNET data link system

MELSECNET data link system is a system which connects the master station and slave stations (local station and remote I/O station) via an optical fiber cable or a coaxial cable.

• Up to 64 local and remote I/O stations in total can be connected to one master station for the second tier.

• Up to 64 local and remote I/O stations in total can be connected to one master station for the third tier.
