CAUTION
• The online operations performed from a PC to a running safety programmable controller
(Program change when a safety CPU is RUN, device test, and operating status change
between RUN and STOP) have to be executed after the manual has been carefully read and
the safety has been ensured.
Following the operating procedure predetermined at designing, the operation has to be
performed by an instructed person.
When changing a program while a safety CPU is RUN (Write during RUN), it may cause a
program breakdown in some operating conditions.
Fully understand the precautions described in the GX Developer's manual before use.
