Safety CPU Operating Status

The following is a list of Safety CPU operating statuses.
• RUN state
• STOP state
• PAUSE state

Operation processing based on safety CPU operating status

Operation processing based on the Safety CPU operating status is the same as that of the standard CPU. ( Page 87
Operation Processing by Operating Status)
Safety communications processing based on safety CPU operating status
Safety communications processing based on the Safety CPU operating status is as follows.
Safety CPU operating status
RUN state
STOP state
PAUSE state
*1 If the safety operation mode is TEST MODE, output is based on the output hold and clear settings when the status of network modules
(RJ71GF11-T2) for which safety communication settings are specified is CPU STOP. (Manual for network module used)
*2 Safety communications are not performed if a stop error occurs at the Safety CPU.
Operation processing when operating status of the Safety CPU
changes
This displays operation processing with the safety program when the operating status of the Safety CPU is changed.
Safety CPU Safety CPU processing
Operating
Safety program
Status
STOP  RUN
Executes safety programs.
RUN  STOP
Executes up to the END
instruction and then stops.
RUN  PAUSE
Stops operation after the
execution of one scan.
PAUSE  RUN
Executes the program from the
start.
PAUSE  STOP
Operation remains stopped.
STOP  PAUSE
Operation remains stopped.
*1 Assignment device data for standard/safety shared labels is processed in the same way as operation processing with standard
programs.
*2 Values for safety devices when the Safety CPU operating status changes are cleared or turn off, regardless of the safety operation
mode.
*3 If the safety operation mode is TEST MODE, output is based on the output hold and clear settings when the status of network modules
(RJ71GF11-T2) for which safety communication settings are specified is CPU STOP. ( Manual for network module used)
Operation processing with standard programs is the same as the following.
