Chxx.HighEngineering REAL 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.
Any value greater than the low
engineering value.
• Current input type: 100.0 = default
• Voltage input type: High signal =
default. For example, with the
-10…10V range, the default = 10.
• RTD input type - By default, the tag
value is the highest temperature
supported by the Sensor Type
connected to the channel.
You can change the value, if necessary.
The engineering units value matches
the Temperature Units that you choose.
For a list of the temperature values
associated with each RTD input sensor
type, see
Table 16 on page 58.
• Thermocouple input type - By
default, the tag value is the highest
temperature supported by the
Thermocouple type connected to the
channel.
You can change the value, if necessary.
The engineering units value matches
the Temperature Units that you choose.
For a list of the temperature values
associated with each Thermocouple
input sensor type, see
Table 16 on
page 58.
Chxx.LLAlarmLimit REAL The Low Low alarm trigger point. Causes the ChxxLLAlarm to trigger when
the input signal moves beneath the configured trigger point. In terms of
engineering units.
0.0 = default
Chxx.LAlarmLimit REAL The Low alarm trigger point. Causes the ChxxLAlarm to trigger when the
input signal moves beneath the configured trigger point. In terms of
engineering units.
0.0 = default
Chxx.HAlarmLimit REAL The High alarm trigger point. Causes the ChxxHAlarm to trigger when the
input signal moves above the configured trigger point. In terms of
engineering units.
100.0 = default
Chxx.HHAlarmLimit REAL The High High alarm trigger point. Causes the ChxxHHAlarm to trigger when
the input signal moves above the configured trigger point. In terms of
engineering units.
100.0 = default
Chxx.RateAlarmLimit REAL The Rate alarm trigger point. Causes the ChxxRateAlarm to trigger when the
input signal changes at a rate faster than the configured rate alarm.
Configured in Engineering Units per second.
0…100
0 = default
Chxx.AlarmDeadband REAL Allows a process alarm to remain set, despite the alarm condition
disappearing, as long as the input data remains within the deadband of the
process alarm.
The deadband value is subtracted from the High and High High Alarm Limits
to calculate the deadband thresholds for these alarms. The deadband value
is added to the Low and Low Low Alarm Limits to calculate the deadband
thresholds for these alarms.
Any non-negative value
0 = default
