Hi..I am just started learning plc programming please tell me how to develop PID  logic controller for VFD Control operation in GX WORKS2,CodesysV2.3

motor used for flow controller

is it possible  implement pid logic  using ladder language in GX Works2,codesys V2.3

GX Works 2 and CodeSys are two different software packages for different brands of PLC. What PLC are you using?

I have using Q PLC for this  GX works 2 software and

Graffic operational controller plc (GOC) for Codesys software used

Yes, the Q-series have PID controllers. Which language do you use in GW2? Mitsubishi have function blocks for using PID controllers in Q-series.

The new inverter FR-A840 has a built-in PLC so that training can start it. It is possible to use the built-in PID in the inverter and there is no need PLC  for example inverter FR-D700, FR-E700 and FR-F700 MITSUBISHI.
