  1. work with Modbus TCP/IP Communication on CPU S7-1200.
    I've configured MB_Server block V3.1, but after 15 min it stops. 
    In MB_Server_DB , Static - Request_Count and Server_Message_Count stop to go up, and Connected stays TRUE.
    After I STOP and then START the CPU, Request_Count and Server_Message_Count, and Connected are reset. And again it stops after 15 min.

    Any ideas?

    CPU - CPU 1214C DC/DC/DC.
    Firmware - V4.0.

    Thank you,

  2. Hello all,

    I was asked to check if there is a PID real - time software which automatically calculates PID loops parameters and update the PLC registers or HMI ( by OPC server etc.) when the process is working and "breathing". REAL-TIME.

    Not PID simulator or PID tuner based on measured data,
    but a software that will calculate and update the PID parameters in real time while maintaning several PID loops simultaneously.

    Are there any suggestions?

    Thank you,
