As far as iI know, and because i experienced it as well, you are use lasted (or 4.x or higher) PID control version. In TIA PORTAL (using S7-PLCSIM V13) you cannot simulate those PID versions (any of them: Compact, TEMP or 3Step V2.x) in a S7-1200. You NEED to downgrade your PID Control version to v3.x (or compact v1.x). For further information, you can check this two links: Why PID_Compact doesnt work PID Problem Both of them explain why the PID control doesn't work when being simulated, also explain how to change PID version for simulation propouses. Hope it helps. Regards, Javier

I had this problem for S7 1200 with TIA 14 SP1 till I checked help of Siemens you will understand compact PID doesn't work for s7 1200.it just works for s7 1500.Siemens has pointed it you can follow it:

Simulating PID_Compact V2 with PLCSIM

Note

Simulation with PLCSIM

The simulation of PID_Compact V2.x with PLCSIM for CPU S7-1200 is not supported.

PID_Compact V2.x can only be simulated for CPU S7-1500 with PLCSIM.

For the simulation with PLCSIM, the time behavior of the simulated PLC is not exactly identical to that of a "real" PLC. The actual cycle clock of a cyclic interrupt OB can have larger fluctuations with a simulated PLC than with "real" PLCs.

In the standard configuration, PID_Compact determines the time between calls automatically and monitors them for fluctuations.

For the simulation of PID_Compact with PLCSIM, for example, a sampling time error (ErrorBits = DW#16#00000800) can therefore be detected.

This results in ongoing tuning being aborted.

The response in automatic mode depends on the value of the ActivateRecoverMode tag.

To prevent this from happening, you should configure PID_Compact for simulation with PLCSIM as follows:

CycleTime.EnEstimation = FALSE
CycleTime.EnMonitoring = FALSE
CycleTime.Value: Assign the cycle clock of the calling cyclic interrupt OB in seconds to this tag
