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 Tags – 1732E-OB8M8SR

Tag Name Type Description

C.ModuleCfgBits SINT 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.
