Description
AlarmDisable
BOOL
Decimal
Alarm Disable
- Disables all alarms for the channel.
ProcessAlarmLatch
BOOL
Decimal
Process Alarm Latch
- Enables latching for all four process alarms:
  • low
  • low low
  • high
  • high high
Latching causes the process alarm to remain set until an unlatch service is explicitly sent to the channel or alarm.
RateAlarmLatch
BOOL
Decimal
Rate Alarm Latch
- Enables latching for the rate alarm. Latching causes the rate alarm to remain set until an unlatch service is explicitly sent to the channel or alarm.
Range
INT
Hex
Range
- Defines the channel’s output range which controls the output signal behavior according to:
  • 0 = -10 to 10V
  • 1 = 0 to 20 mA
DigitalFilter
REAL
Float
Digital Filter
-
Specifies the time constant, in milliseconds, for a digital first order lag filter on the input. The digital filter smooths input data noise transients for the selected channel on the module. A value of 0 disables the filter.
RateAlarmLimit
REAL
Float
Rate Alarm Limit
- The trigger point for the rate alarm status which is set if the input signal changes at a rate faster than the configured rate alarm. This point is configured in percent full scale per second.
LowSignal
REAL
Float
Low Signal
- One of four points used in scaling. The low signal is in terms of the inputs signal units and corresponds to the low engineering term when scaled. Uses the scaling equation.
HighSignal
REAL
Float
High Signal
- One of four points used in scaling. The high signal is in terms of the inputs signal units and corresponds to the high engineering term when scaled. Uses the scaling equation.
LowEngineering
REAL
Float
Low Engineering
- One of four points used in scaling. The low engineering helps determines the engineering units the signal values scale into. The low engineering term corresponds to the low signal value. Uses the scaling equation.
HighEngineering
REAL
Float
High Engineering
- One of four points used in scaling. The high engineering helps determines the engineering units the signal values scale into. The high engineering term corresponds to the high signal value. Uses the scaling equation.
LAlarmLimit
REAL
Float
Low Alarm Limit
- The low alarm trigger point. Causes the Ch0LAlarm to trigger when the input signal moves beneath the configured trigger point. In terms of engineering units.
HAlarmLimit
REAL
Float
High Alarm Limit
- The high alarm trigger point. Causes the Ch0HAlarm to trigger when the input signal moves above the configured trigger point. In terms of engineering units.
LLAlarmLimit
REAL
Float
Low Low Alarm Limit
- The low low alarm trigger point. Causes the Ch0LLAlarm to trigger when the input signal moves beneath the configured trigger point. In terms of engineering units.
HHAlarmLimit
REAL
Float
High High Alarm Limit
- The high high alarm trigger point. Causes the Ch0HHAlarm to trigger when the input signal moves above the configured trigger point. In terms of engineering units.
AlarmDeadband
REAL
Float
Alarm Deadband
- Forms a deadband around the process alarms which causes the corresponding process alarm status member to remain set until the input moves beyond the trigger point by greater than the amount of the alarm deadband.
