Description
The percent of range of the current combustibles reading.
The combustibles calibration constant from the previous good cali-
bration.
The combustibles calibration slope from the previous good
calibration.
The value and status of the combustibles concentration reading.
The High and Low range limit values, the engineering units code,
and the number of digits to the right of the decimal point for the
combustibles reading.
See FF-903 section 3.3.
The raw value of the combustibles reference input.
The combustibles cell temperature. This is the determined from the
value of the combustibles reference RTD.
The High and Low range limit values, the engineering units code,
and the number of digits to the right of the decimal point for the
combustibles cell temperature reading.
See FF-903 section 3.3.
Combustible Reference current.
See FF-903 section 3.3 and 4.3.
Combustibles heater temperature set point.
The combustibles calibration slope.
The combustible slope warning threshold.
The amount of time that the combustibles process variable will take
to reach 90% of the actual process variable.
The highest Combustibles temperature read since power on.
Combustible Block T/C voltage (Valid only with Type 3 sensor).
The time until the next automatic calibration of the combustibles
sensor.
Combustible calibration gas tolerance check.
The duration of the Combustibles sensor zero cycle.
Indicates whether Combustibles sensor zero is enabled.
The time between Combustibles sensor zero cycles.
Indicates whether the Combustibles analog output should track the
input during Combustibles sensor zero or lock at the last process
reading. (0=None, 1=O , 2=CO
2
The duration of the Combustibles sensor zero purge.
The current step of the Combustibles sensor zero cycle. (0=Idle,
1=Flowing, 2=Purging)
Indicates whether the Combustibles calibration constants should be
updated after Combustibles sensor zero.
A bit-enumerated value used to communicate the status of the OCX.
(This is similar in nature to the command 48 status bits in HART).
A bit-enumerated value used to communicate the status of the OCX.
(This is similar in nature to the command 48 status bits in HART).
