Table 33 - Standard Input Module Configuration Tags
Name Data Type Definition
COSOnOffEn
(1bit per point) DINT Change of State On to Off—Causes updated data to be sent to the controller immediately after an input for an On to Off
transition of the masked input points. The CST timestamp also is updated. May be used to trigger an event task in the
controller.
0 = Disable
1 = Enable
COSOffOnEn
(1 bit per point) DINT Change of State Off to On—Causes updated data to be sent to the controller immediately after an input for an Off to On
transition of the masked input points. The CST timestamp also is updated. May be used to trigger an event task in the
controller.
0 = Disable
1 = Enable
FilterOnOff_0_7…
(1 byte per group) SINT Filter Times On to Off—Filter time for digital filter in digital input modules for On to Off transition. Operates on groups
of eight points.
Valid DC filter times = 0, 1, 2, 9, 18 ms
Valid AC filter times = 1, 2 ms
FilterOffOn_0_7…
(1 byte per group) SINT Filter Times Off to On—Filter time for digital filter in digital input modules for Off to On transition. Operates on groups
of eight points.
Valid DC filter times = 0, 1, 2 ms
Valid AC filter times = 1, 2 ms

Name Data Type Definition
CSTTimestamp
(8 bytes) DINT[2] Coordinated System Time Timestamp—Timestamp can be configured to indicate the time that data changed (see
COSOffOnEn, COSOnOffEn, COSStatus, DiagCOSDisable) and/or the time that a diagnostic fault occurred (see OpenWireEn,
Field PwrLossEn).
Data
(1 bit per point) DINT Off/On—Status for each input point.
0 = Off
1 = On
Fault
(1 bit per point) DINT Fault Status—An an ordered status of faults that indicates a point is faulted and input data for that point may be
incorrect. Check other diagnostic faults, if they are available, for further diagnosis of the root cause. If communication to
the input module is lost, then all points for the module will be faulted.
0 = No fault
1 = Fault (OpenWire or FieldPwrLoss or Comm Fault)
Table 35 - Diagnostic Input Module Configuration Tags
Name Data Type Definition
COSOnOffEn
(1bit per point) DINT Change of State On to Off—Triggers an event in the controller for On to Off transition of input point and causes the
input module to update the data table as soon as possible. The CST timestamp is also updated.
0 = Disable
1 = Enable
COS OffOnEn
(1 bit per point) DINT Change of State Off to On—Triggers an event in the controller for Off to On transition of input point and causes the
input module to update the data table as soon as possible. The CST timestamp is also updated.
0 = Disable
1 = Enable
DiagCOSDisable
(1 bit per point) BOOL Diagnostic Change of State—Triggers the module to transmit diagnostic status data with an updated timestamp as
soon as the diagnostic data changes state.
FaultLatchEn
(1 bit per point) DINT Latch Fault—If enabled for a point, any OpenWire or FieldPwrLoss stays latched in the faulted state even if the fault no
longer exists until you clear the fault.
0 = Disable
1 = Enable latching
FieldPwrLossEn
(1 bit per point) DINT Field Power Loss—Enables Field Power Loss diagnostic.
0 = Disable
1 = Enable
