*2. When the operating mode changes from PROGRAM mode to DEBUG mode, the safety application data in
the non-volatile memory of the Safety CPU Unit
is deleted.
*3. The Safety CPU Unit automatically enters PROGRAM mode if 30 seconds elapses after the connection to
the Sysmac Studio is disconnected due to a damaged cable or any other reason.
*4. The DIP switch setting and the restore mode are not available with NX-SL3300 and NX-SL3500.
Additional Information
If you need to use debugging to change present values or other settings while operating in RUN
mode (for instance, to troubleshoot a validated safety program), you must stop the machine,
and then change the Safety CPU Unit to PROGRAM mode before you can change to DEBUG
mode. However
, when the operating mode changes from PROGRAM mode to DEBUG mode,
the safety programs in the non-volatile memory of the Safety CPU Unit is deleted. Download
the safety-validated safety programs to the non-volatile memory in the Safety CPU Unit again.
Version Information
The processing that is performed when the operating mode changes from RUN mode to PRO-
GRAM mode depends on the version of the Sysmac Studio that you use.
• Sysmac Studio version 1.09 or lower
The safety programs in the non-volatile memory of the
Safety CPU Unit are deleted. If you
return to RUN mode, download the safety-validated safety programs to the non-volatile mem-
ory in the Safety CPU Unit again.
• Sysmac Studio version 1.10 or higher
The safety programs in the non-volatile memory of the Safety CPU Unit are not deleted.
