This check box indicates whether the interlock check is enabled or disabled. A selected check box indicates that the interlock check is enabled. A cleared check box indicates that the interlock check is disabled.
-
Synchro Check—Enables the synchro check on the device that, after accepting the operate request, dynamically checks for when the control object can execute the operation. This check box indicates whether the synchro check is enabled or disabled. A selected check box indicates that synchro check is enabled. A cleared check box indicates that synchro check is disabled
-
