10.1.3.10 Output test mode
To operate on outputs, select Output in the Contact I/O Selection drop-down menu. Each
output can be placed into one of four states: Disabled causes the output to ignore test mode
and to act as if test mode was turned off; Energized and De-energized override the output state
and set it to high and low state respectively; Freeze causes the output to remain in its current
state, overriding any other state that the output may transition into. Click Apply to assign new
states. Outputs remain in the assigned states until they are changed, until test mode is turned
off, or the CPUs are restarted.

CPUs can log several events related to the discrete I/Os. Events can be grouped into three
categories: configuration, confirmation, and operation events. All events falling within these
categories are described in sections that follow.
