And what happens when everything works, and the problem comes randomly? That means, that I can write to a variable without problems but, sometimes, the communication between PLC and HMI is faulty and then come to this error. I know that communication is faulty because I have a life bit that stops changing, and then I can not read or write variables to the SPS. The panel is TP900, PLC 1518F and programmed with TIA Portal V13 SP1 Upd.9 Thanks in advance! ------------------------------------------------------------------------------------------ |
