In the PF Map, open Accessories>Digital I/O and double-click
Diagnostic, or right-click Diagnostic and select Open I/O
Diagnostic.

This function enables testing of the interaction between PF and different external devices. For instance, it
could be useful when trouble shooting complex systems with one or several PLC units connected to the
controller.

to update this view to reflect changes.
Output test function activates and de-activates relays on a selected I/O device when Set is clicked.
The Restore key restores the relays to reflect the current status of the PF. Click Read to update this view
to reflect changes triggered by other events.
