SENSOR_MEAS_TYPE
17
Mathematical function to calculate PRIMARY_VALUE (PV).
Defined codes:
0: PV = SV_1
1: PV = SV_2
128: PV = SV_1 - SV_2 Difference
129: PV = SV_2 - SV_1 Difference
192: PV = ½ * (SV_1 + SV_2) Average
193: PV = ½ * (SV_1 + SV_2) Average, but SV_1 or
SV_2 if the other is wrong (input_fault_x
≠
0)
220: PV = SV_1, SV_2 not available. Used for single
sensor applications. If selected, Sensor 2 will
not be measured. All parameters exclusively
related to Sensor 2 are not available, and no
alarms will be generated for Sensor 2.
221: PV = SV_1, but SV_2 if SV_1 is wrong
(INPUT_FAULT_1
≠
0)
222: PV = SV_2, but SV_1 if SV_2 is wrong
(INPUT_FAULT_2
≠
0)
