Functions for Checking Operation
This section describes the functions that you use on the Sysmac Studio to check the operation on the
Safety CPU Unit.
You can check and adjust the operation of safety programs through an online connection between the
Sysmac Studio and the Safety CPU Unit. This allows you to control BOOL variables, change present
values, and perform other debugging tasks.

WARNING
Before you start the system, perform user testing to make sure that all
safety devices operate correctly.
Serious injury may possibly occur due to loss of required safety func-
tions.
WARNING
Always confirm safety at the destination node before you transfer Unit
configuration information, parameters, settings, or other data from tools
such as the Sysmac Studio. The devices or machines may operate un-
expectedly, regardless of the operating mode of the Controller
