C.Ch0LEngineering
C.Ch1LEngineering
C.Ch2LEngineering
C.Ch3LEngineering
INT
One of four points used in scaling. The low engineering 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:
C.Ch0HEngineering
C.Ch1HEngineering
C.Ch2HEngineering
C.Ch3HEngineering
INT
One of four points used in scaling. The high engineering helps determine the engineering units the
signal values scale into. The high engineering term corresponds to the high signal value. The scaling
equation used is as follows:
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.Ch0LimitAlarmLatch
C.Ch1LimitAlarmLatch
C.Ch2LimitAlarmLatch
C.Ch3LimitAlarmLatch
SINT
Enables latching for all four process alarms: low, low low, high and high high. Latching causes the
process alarm to remain set until an unlatch service is explicitly sent to the channel or alarm.
C.Ch0NotchFilter
C.Ch1NotchFilter
C.Ch2NotchFilter
C.Ch3NotchFilter
SINT
Configures the channel’s notch filter settings.
See
for list of valid input values.
C.Ch0SensorType
C.Ch1SensorType
C.Ch2SensorType
C.Ch3SensorType
SINT
Configures the channel’s sensor type settings.
See
for list of valid sensor types.
C.Ch0DigitalFilter
C.Ch1DigitalFilter
C.Ch2DigitalFilter
C.Ch3DigitalFilter
INT
A non-zero value enables the filter. The value serves as a time constant in milliseconds that can be
used in a first order lag filter to smooth the input signal.
C.Ch0LAlarmLimit
C.Ch1LAlarmLimit
C.Ch2LAlarmLimit
C.Ch3LAlarmLimit
INT
The low alarm trigger point. This value causes the Ch<0...3>LAlarm bit to trigger when the input signal
moves beneath the configured trigger point, in engineering units.
