Process Dual Sensor Analog Input (PAID)

This information applies to the CompactLogix 5380P and ControlLogix 5580P controllers.
The Process Dual Sensor Analog Input (PAID) instruction monitors one analog Process Variable (PV) by using two analog input signals, from sources such as dual sensors, dual transmitters, and dual input channels. The PAID instruction monitors conditions of the channels and reports configured PV quality. The PAID instruction has functions for input selection, averaging, and failure detection. Additional functions, such as for filtering and alarming, are done by a downstream PAI block.
The PAID Instruction provides:
  • Selection of the sensor or input A value, the sensor or input B value, the average of the two, the lesser of the two, or the greater of the two as the PV value.
  • Input Source and Quality monitoring for uncertain or bad input for each sensor, transmitter, or input, plus monitoring of each signal for out-of-range condition. If one PV is bad, failed, or out or range, the other PV is automatically selected.
  • Warning alarm if the difference between the two sensor PVs exceeds a configured limit.
  • Warning alarm if only one PV has good quality.
  • Warning alarm if neither PV has good quality; for example, if both are uncertain.
  • Failure alarm if both PVs are bad; for example, each PV has bad quality (Inp_PVABad or Inp_PVBBad) or is outside the configured failure range.

IMPORTANT:
Unexpected operation may occur if:
  • Output tag operands are overwritten.
  • Members of a structure operand are overwritten.
  • Except when specified, structure operands are shared by multiple instructions.
There are data conversion rules for mixing numeric data types within an instruction. See Data conversions.

Example
This example uses the PAID instruction to monitor one analog Process Variable (PV) using two analog input signals (dual sensors, dual transmitters). The PAID instruction allows you to select one sensor, the other sensor, or the average, minimum or maximum of either sensors. If difference between the two input signals exceeds a configured limit, an Alarm is generated.
In this example, an application uses two analog sensors (A, B). The average of these analogs is used elsewhere in logic to control a separate application element.
The Inp_PVAData and Inp_PVBData parameters are connected to the values from the two analog transmitters. The fault status of each of these sensors is tied to the bad input of the instruction (for example, Inp_PVABad). The output parameters Val, Sts_PVBad and Sts_PVUncertain, can then be connected to the Inp_PVData, Inp_PVUncertain and Inp_ChanFault for control.
