    I am trying to use a PID control in Netsyst controller, but when I compile my project, LogicLab output this error:

    Code generation …
    Preprocessing EmbeddedElements completed.

    FT_INT(16) – error A4097: SYSTIMER => Object not found
    FT_DERIV(13) – error A4097: SYSTIMER => Object not found

    The error reports that the external variable SYSTIMER is not present in the target (This variable is probably used by the PID FB). Which FB are you using ?

    It seems that you are not using our PIDMng function block (Manual abstract). You can download the project reported in this topic and modify the target to Netlog. The project can be tested also on the PC simulator.

    The SYSTIMER is reported in capital letters because you have not selected the Case sensivity (As we suggest) in the Project -> Option menu (Screenshot).
