DANGER
● When data change, program change, or status control is performed from a personal computer to a running
programmable controller, create an interlock circuit outside the programma ble controller to ensure that the whole
system always operates safely.
Furthermore, for the online operations performed from a personal comp uter to a programmabl e controller CPU, the
corrective actions against a communication error due to such as a cable connection fault should be predetermined as
a system.
CAUTION
● The online operations performed from a personal computer to a running programmable controller CPU (Program
change when a programmable co ntroller CPU is RUN, operating status change such as RUN-ST OP switching, and
remote control operation) have to be executed after the manual has been carefully read and the safety has been
ensured.
When changing a program while a programmable controller CPU is RUN, it may cause a program corruption in some
operating conditions. Fully understand the precautions described in GX Works2 Ve rsion1 Operating Manual
(Common) before use.
