Note:
When the value of a contact changes from Off to On or from On to Off, the Before and After
fields are updated with the status of the contact before the change occurred and the status
of the contact after the change occurred. The Change field is also updated with the new
value.

When you select a digital output module (FP-DO-401), a window appears similar to the one
shown in
Figure 134: Digital Output module information on page 186. For each module a
graphical display shows the available output contacts. A grey switch directed to the bottom
indicates a discrete output value is Off; a grey switch directed to the upwards position indicates
a discrete output value is On. In Figure 134: Digital Output module information on page 186,
contacts 01 and 04 and 07 are On; all others are Off.
