7 Checking Operation and Actual Operation
*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.
Operating Modes of Safety CPU Unit and Indicators
The following table specifies details of the Safety CPU Unit operating modes and the indicators dis-
played for each operating mode.

This mode indicates that the Safety CPU Unit is starting up and per-
forming hardware self-diagnosis.
This mode indicates that safety communications and the safety pro-
gram execution are stopped.
You can clear or download the safety application data from the Sys-
mac Studio (Safety CPU Unit Setup and Programming View).
This mode indicates that safety communications are executed and
the validated safety programs are running.
the unvalidated safety programs are on standby.
You can control BOOL variables, change present values of data, and
use forced refreshing.
This mode indicates that safety communications are executed and
unvalidated safety programs are running.
You can control BOOL variables, change present values of data, and
use forced refreshing.
This mode allows you to edit user programs and settings of the Safe-
ty CPU Unit by using an SD Memory Card.
Safety communications and safety programs are not executed.
