Configuration, Input, Output Tags for 1732E-OB8M8SR

The following table describes the configuration tags generated in RSLogix 5000
software when you use your 1732E-OB8M8SR module.

Output Tags – 1732E-IB8M8SOER

Tag Name

Type

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

SINT

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.PtToRetrieve

SINT

When RetrieveByPoint is set, determines point requested for events to be returned. Allows a user to
query events in the sequence they happened by point instead of the overall sequence the events
occurred.

O.ResetEvents

BOOL

Erases all recorded events when transitioned from 0…1.

O.RetrieveByPt

BOOL

Changes retrieval mechanism from sequential (when 0) to retrieving events on a per point basis
according to value set in PointToRetrieve field.

Configuration Revision Number.

C.ProgToFaultEn

BOOL

Selects whether (enabled) or not (disabled) to apply the fault value when the output is
already being set to the program value when a Fault (connection timeout) occurs in
Program Mode.
