Setting Fault Action to Fail-safe

    Last Modified: September 6, 2017

    The Fault table populates based on the channel configurations you select.

    Figure 1. Fault Table

    If you check the box next to a fault, that fault will trigger the module to go into Fail-safe Mode. Checking the box also reserves that signal so it cannot be used in the state machine diagram. If you leave the box unchecked, you can use that signal as an input to trigger transitions in the state machine diagram.


    All fault signals listed in the Fault table must be set to trigger Fail-safe Mode or used in the state machine diagram. If a fault signal remains unused and that fault is detected, the detected fault will not be reported by the User Program.


    Copy and paste the fault name to avoid retyping it in the state machine diagram. Click on the fault name and press <Ctrl-C> to copy the fault name in the I/O Configuration table.
