C.Ch0LimitAlarmLatch
C.Ch1LimitAlarmLatch
C.Ch2LimitAlarmLatch
C.Ch3LimitAlarmLatch SINT Enables latching for the process alarms. Latching causes the process alarms to remain set until an
unlatch service is explicitly sent to the channel or alarm.
C.Ch0AlarmDisable
C.Ch1AlarmDisable
C.Ch2AlarmDisable
C.Ch3AlarmDisable SINT Disables all alarms for the channel:
0 – Alarms are not disabled
1 – Alarms are disabled
C.RealTimeSample INT Configures real-time sampling on a module-wide basis.
See
Real-time Sampling on page 46 for more information.

I.Fault DINT Collection of all module level fault bits.
I.Ch0Fault
I.Ch1Fault
I.Ch2Fault
I.Ch3Fault BOOL Individual channel fault status bit. Indicates a ‘hard’ fault has occurred on the channel that means:
calibration is ongoing; or if an input, an overrange or underrange condition is present; or if an output, a
low or high clamp condition is occurring. These bits also are set by the controller if communication is
lost with the I/O module.
I.Ch0Calibration
I.Ch1Calibration
I.Ch2Calibration
I.Ch3Calibration BOOL Indicates if calibration is currently in progress on a channel.
I.Ch0LAlarm
I.Ch1LAlarm
I.Ch2LAlarm
I.Ch3LAlarm BOOL Low alarm bits that set when the input signal moves beneath the configured low alarm trigger point,
Ch<0...3>LAlarmLimit. Remains set until the input signal moves above the trigger point, unless latched
via Ch<0...3>LimitAlarmLatch, of the low alarm trigger point.
I.Ch0HAlarm
I.Ch1HAlarm
I.Ch2HAlarm
I.Ch3HAlarm BOOL High alarm bit that sets when the input signal moves above the configured high alarm trigger point,
Ch<0...3>HAlarmLimit. Remains set until the input signal moves below the trigger point, unless latched
via Ch<0...3>LimitAlarmLatch.

C.Ch0FaultValue
C.Ch1FaultValue
C.Ch2FaultValue
C.Ch3FaultValue INT Defines the value, in counts, the output should take if a communication fault occurs when the
ChxFaultMode bit is set.
Where: x = output channel.
C.Ch0ProgramValue
C.Ch1ProgramValue
C.Ch2ProgramValue
C.Ch3ProgramValue INT Defines the value, in counts, the output should take when the connection transitions to Program mode
if the ChxProgMode bit is set.
Where: x = output channel.
C.Ch0LEngineering
C.Ch1LEngineering
C.Ch2LEngineering
C.Ch3LEngineering INT The low engineering value helps determine the engineering units the signal values scale into. The low
engineering term corresponds to the low signal value. The scaling equation used is as follows:
Data =
(Signal-LowSignal)(HighEngineering-LowEngineering)
High Signal - Low Signal
+ Low Engineering
