Pid Monitor - IDEC MICROSmart FC6A Series Ladder Programming Manual

PID Monitor

Function Description
While PID control is executing, you can graphically monitor the PIDA/PIDD instruction parameters. From the PID Monitor dialog
box, you can also directly change the values of data registers and internal relays that are being used by the PIDA/PIDD
instructions, and check the operation of the PIDA/PIDD instructions while adjusting the PID control parameters.
Note: The PID monitor operates according to the PIDA/PIDD instruction settings in the ladder program displayed on the WindLDR and not
according to the settings in the PLC. If the device allocations for the PIDA/PIDD instruction in the PLC and the PIDA/PIDD instruction in WindLDR
are different, the PID instruction is not correctly monitored.
