Tag Definitions Appendix B
Table 46 - 1756-IB16IF Module Event Tags
Name Data Type Tag Definition Module Definition
Fault DINT Fault Status—Indicates whether a point is faulted. If communication to the input
module is lost, then all 32 bits will be set. For more information, see
page 106 .
0 = No fault has occurred.
1 = A fault has occurred.
Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
Event[x].NewEvent BOOL New Event—Indicates whether a new event has occurred. This bit is cleared only when
acknowledged by the Event[x].NewEventAck output tag or reset by the ResetEvents
output tag.
0 = No new event has occurred since the last acknowledged event.
1 = A new event has occurred since the last acknowledged event. Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
Event[x].EventDropped BOOL Event Dropped—Indicates whether an event has been dropped:
• If the LatchEvents output tag is set, the last recorded event is retained until
acknowledged, and a subsequent event is dropped.
• If the LatchEvents output tag is cleared, the last unacknowledged event is overwritten.
0 = An event has not been dropped.
1 = An event has been dropped.
Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
Event[x].CIPSyncValid BOOL CIP Sync Valid—Indicates whether a valid CIP Sync time master existed on the
backplane at the time of an event.
0 = CIP Sync was not available on the backplane at the time of an event.
1 = CIP Sync was available on the backplane at the time of an event. Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
Event[x].CIPSyncTimeout BOOL CIP Sync Timout—Indicates that a valid CIP Sync time master existed on the backplane
at the time of an event, but has since timed out.
0 = CIP Sync has not timed out.
1 = CIP Sync was available on the backplane, but has since timed out prior to the event
occurring. Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
Event[x].Data INT Module Data—Shows the input data for all 16 points on the module at the time an
event occurs. Data for bits 0…15 is shown as a bit mask where bit 0 is Pt[0].Data and bit
15 is Pt[15].Data.
0 = On a per bit basis, indicates the corresponding bit in the Pt[x].Data input tag was Off
when the event occurred.
1 = On a per bit basis, indicates the corresponding bit in the Pt[x].Data input tag was On
when the event occurred. Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
Event[x].Timestamp DINT Event Timestamp—Records a 64-bit timestamp in CIP Sync format at the time an
event occurs. Connection = Data with Event or Listen
Only with Event
Input Data = Timestamp Data
