[Design Precautions]

!WARNING

•For the operation status of each station at communication error in each station, refer to the

respective manual for each station.

The communication error may result in an accident due to incorrect output or malfunction.

•When using the notification function, the pager receiver may not be contacted due to the

frequency transmission status from the system setup environment and error on the receiver

side.

To ensure the safety of the programmable controller system, install a call circuit with a lamp

display or buzzer sound.

•When connecting a peripheral with the CPU module or connecting an external device, such as a

personal computer, with an intelligent function module to modify data of a running

programmable controller, configure an interlock circuit in the program to ensure that the entire

system will always operate safely.

For other forms of control (such as program modification or operating status change) of a

running programmable controller, read the relevant manuals carefully and ensure that the

operation is safe before proceeding.

Especially, when a remote programmable controller is controlled by an external device,

immediate action cannot be taken if a problem occurs in 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.
