(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".
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.
[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.
DANGER
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 medium or slight personal injury or physical damage.
