Monitoring a Channel or a Slot
You may need to continuously monitor the current status of a particular
switching channel, a digital I/O port, or an entire plug-in module. This is
especially useful when developing and debugging remote interface
commands or watching for an important signal.

To monitor a channel or a port, specify the channel or port number.
To monitor a plug-in module, specify the slot number. The displayed
information is module type dependent as shown on the next page.
•
Front-Panel Operation: To select a channel, a digital I/O port, or a
slot, press Mon. The MON annunciator lights up. Press Mon again
to exit this state.
If only part of the channel status on the module can be displayed at
one time, press Enter to display the next part.
