[Startup and Maintenance precautions]
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 such as RUN-STOP switching) 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.
