Latches
—When the value of a digital input point changes from off to on, an on-latch is automatically set.
While the value of the point may return to off, the on-latch remains set until cleared, as a record of the change.
Similarly, an off-latch is set when the value of a digital point changes from on to off, and it remains set until
cleared. Latching is automatic and needs no configuration.
