WARNING
• Build an interlock circuit outside the PLC system to ensure that the whole system always works
safely when changing the data of the running PLC or controlling the PLC status from the
personal computer.
In addition, be sure to incorporate the corrective action into the system to deal with the
communication error due to the poor cable connection while operating the PLC CPU online from
the peripheral device.

[Operating Precautions]
!
CAUTION
• Read the manual carefully and confirm the safety before connecting a personal computer with
the running CPU module to perform the online operation (especially forced output and operating
status change).
Misoperation may cause the machine damage or accidents.
