[INSTALLATION PRECAUTIONS]
DANGER
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.
CAUTION
