The unvalidated safety programs are transferred from the Sysmac Studio to the main memory in
the Safety CPU Unit, and the Safety CPU Unit enters the DEBUG mode (STOPPED).
Precautions for Correct Use
Before safety is validated, the safety programs are stored in the main memory of the Safety
CPU Unit. When the Sysmac Studio is taken offline or the power supply to the Safety CPU Unit
is turned OFF in this state, the safety programs are deleted. Because of this, after you cycle the
power supply, you must use the Sysmac Studio to change to DEBUG mode again and transfer
the safety programs to the main memory again.
Changing to PROGRAM Mode
If you need to change the safety program, you must change to PROGRAM mode.
Use the following procedure to change the Safety CPU Unit from DEBUG mode to PROGRAM mode.
With the Safety CPU Unit in DEBUG mode, perform one of the following operations.
−
