■In SAFETY MODE
The following table lists file operations which are available for each file type in SAFETY MODE.
: Available, : Not available, : N/A
*1 To write files to the programmable controller, use the write function when the operating status of the SIL2 Process CPU is STOP. When
the operating status is RUN, use the online change function. When the SIL2 Process CPU operating status is RUN, only the standard
programs registered in the CPU parameter can be written to the programmable controller.
*2 Operation is possible only when the operating status of the SIL2 Process CPU is STOP/PAUSE. If any file operation is performed in the
RUN state, the operating status of the SIL2 Process CPU is changed by the remote STOP function, and then the operation continues.
*3 This parameter relates to safety control inside the CPU parameters. ( Page 936 Safety CPU parameters)
This item is yellow in the engineering tool CPU parameters.
*4 Writing is possible in file units, however, it is not possible to select files together with parameter files or files relating to safety and then
write to the programmable controller CPU. If writing in file units, write after clearing the selection of other parameter files or files relating
to safety, or write after switching to TEST MODE.
*5 Operation is possible only when the operating status of the SIL2 Process CPU is STOP/PAUSE. A communication error occurs when
the file is operated in the RUN state.
