10.1.3.7 Contact output states
While CPUs are running they provide the current states of discrete outputs. To view this
information, click CO States in the Discrete Inputs/Outputs dialog box. The list contains all
configured discrete outputs with its corresponding user-friendly name and current state. The
information on the screen is a snapshot of the states taken at the time the dialog box was
opened.
NOTE: In order to see the latest states of the outputs, the dialog box must be closed and
reopened.
Off means that the output is de-energized and On indicates that the output is energized.

10.1.3.8 Test mode
Discrete I/Os can be placed into test mode which enables the states of the I/Os that are read or
assigned during normal system operation to be overridden. To enter test mode, click Force
Contact I/O in the Discrete Inputs/Outputs dialog box and click to select the Test Mode Enable
check box. Choose which type of I/O points are displayed by selecting an option in the Contact
I/O box. When the test mode is enabled, it is active for both inputs and outputs until it is either
turned off or the CPUs are restarted.
