Description
DiagCOSDisable
(per device)
BOOL
Decimal
  • 0 = Allows diagnostic fault (for example, OpenWire, FieldPwrLoss) to also trigger Change of State (COS) event in controller
  • 1 = Only a change in input Data triggers COS event in controller
See COSOnOffEn, COSOffOnEn , CSTTimestamp.
FilterOffOn_0_7
(1 byte per group)
SINT
Decimal
Filter Times OFF to ON
 - Filter time for digital filter in digital input devices for OFF to ON transition. Operates on a group of 8 points.
  • Valid DC filter times = 0, 1, 2 msec
  • Valid AC filter times = 1, 2 msec
FilterOnOff_0_7
(1 byte per group)
SINT
Decimal
Filter Times ON to OFF -
Filter time for digital filter in digital input devices for ON to OFF transition. Operates on a group of 8 points.
  • Valid DC filter times = 0, 1, 2, 9, 18 msec
  • Valid AC filter times = 9, 18 msec
COSOnOffEn
DINT
Binary
Change of State ON to OFF
 - Triggers an event in the controller for an ON to OFF transition of input point and causes the input device to update the data table as soon as possible. Also updates the CSTTimestamp.
  • 0 = Disable
  • 1 = Enable
COSOffOnEn
DINT
Binary
Change of State OFF to ON
 - Triggers an event in the controller for and OFF to ON transition of input point and causes the input device to update data table as soon as possible. Also updates the CSTTimestamp.
  • 0 = Disable
  • 1 = Enable
FaultLatchEn
DINT
Binary
Fault is Latched
 - When enabled for a point, any OpenWire or FieldPwrLoss stays latched in the faulted state until you clear the fault, even if the fault no longer exists.
  • 0 = Disable
  • 1 = Enable
OpenWireEn
DINT
Binary
Open Wire
 - Enables Open Wire diagnostic.
  • 0 = Disable
  • 1 = Enable
FieldPwrLossEn
DINT
Binary

 - Enables Field Power Loss diagnostic.
  • 0 = Disable
  • 1 = Enable
