Scales both the range and the limits for the process value. If the process value goes below the low limit or

above the high limit, the PID loop goes to inactive mode and sets the output value to 0.

To use Input_PER, you must scale the analog process value (input value).

Configuration editor for PID_Compact (Basic settings)

Selects the engineering units.

Allows selection of a reverse-acting PID loop.

If not selected, the PID loop is in direct-acting mode and the output of PID loop

increases if input value < setpoint.

If selected, the output of the PID loop increases if the input value > setpoint.

Restarts the PID loop after it is reset or if an input limit has been exceeded and

returned to the valid range.

Selects either the Input parameter or the Input_PER parameter (for analog) for the

process value. Input_PER can come directly from an analog input module.

Selects either the Output parameter or the Output_PER parameter (for analog) for

the output value. Output_PER can go directly to an analog output module.
