Output Tags

The following table describes the output tags generated in RSLogix 5000.

Description

O.EventAck

DINT

For the bits selected in the O.NewDataAck tag, this tag selects which edge to acknowledge,
On to Off, Off to On or both.

0 = acknowledging an ON to OFF event
1 = acknowledging an OFF to ON event
2 = acknowledging both ON to OFF and OFF to ON events

The O.NewDataAck tag must also be used to acknowledge the event(s).

O.NewDataAck.x

INT

Allows I.NewData bits and I.Timestamp data updates in the Input tag to function as
intended. I.NewData bits are set and I.Timestamp data updates when a transition occurs
and clear only after they are acknowledged via the O.NewDataAck bit. Typically, the
following events occur:

An event occurs on an input.

The module sets the I.NewData bit and I.Timestamp data for the input where the
event occurred.

The controller records the new data.

The controller acknowledges the new data by causing a 0 to 1 transition on the
corresponding O.NewDataAck bit.

The I.NewData bit and I.Timestamp data clears.

When another event occurs on the input, the sequence begins at the top bullet in
this list.

The controller must cause a 0 to 1 transition in this bit to acknowledge new data for an
input; in other words, if the NewDataAck bit is 0 when new data is received, the controller
must change this bit to 1 to acknowledge the data. If NewDataAck bit is 1 when new data
is received, the controller must change this bit to 0 and then at least one RPI later to 1 to
acknowledge the new data.

O.PointToRetrieve

SINT

Not used in this mode.

O.ResetEvents

BOOL

Erases all recorded events when transitioned from 0 to 1.

O.RetrieveByPoint

BOOL
