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:
C.Ch0HEngineering
C.Ch1HEngineering
C.Ch2HEngineering
C.Ch3HEngineering
INT 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.Ch0Filter
C.Ch1Filter
C.Ch2Filter
C.Ch3Filter
INT Configures the channel’s filter settings. A non-zero value enables the filter. The value serves as a time
constant in milliseconds that can be used in a first order lowpass filter to smooth the input signal.
See Digital Filters on page 44 for more information.
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.
See Alarm Configuration Tab
on page 26 and Process Alarms on page 46 for more information.
C.Ch0HAlarmLimit
C.Ch1HAlarmLimit
C.Ch2HAlarmLimit
C.Ch3HAlarmLimit
INT The high alarm trigger point. This value causes the Ch<0...3>HAlarm bit to trigger when the input signal
moves above the configured trigger point, in engineering units.
See Alarm Configuration Tab
on page 26 and Process Alarms on page 46 for more information.
C.Ch0LLAlarmLimit
C.Ch1LLAlarmLimit
C.Ch2LLAlarmLimit
C.Ch3LLAlarmLimit
INT The low low alarm trigger point. This value causes the Ch<0...3>LLAlarm bit to trigger when the input
signal moves beneath the configured trigger point, in engineering units.
See Alarm Configuration Tab
on page 26 and Process Alarms on page 46 for more information.
C.Ch0HHAlarmLimit
C.Ch0HHAlarmLimit
C.Ch0HHAlarmLimit
C.Ch0HHAlarmLimit
INT The high high alarm trigger point. This value causes the Ch<0...3>HHAlarm bit to trigger when the input
signal moves above the configured trigger point, in engineering units.
See Alarm Configuration Tab
on page 26 and Process Alarms on page 46 for more information.
C.Ch0Range
C.Ch1Range
C.Ch2Range
C.Ch3Range
SINT Configures the input range for the channel.
