Once a month, in our factory, the power is shut off for about 40 minutes ( faults, repairers etc.). After the faults I have problem with automatic reawaking the profibus net and visualization system with WinCC server. Industrial net is built with Siemens PLC’s (S7300), few computers with visualization, control and server which task is to archive information and visualization when needed.
Few months ago UPS with active termination was installed – placed where in profibus nets is needed - we suspect that the WinCC server Siemens card after reawaking the supply and reconfiguring the net has some errors because always server restart is the solution. This terminator task was to help server reconnect with PLCs.
It seems that it doesn’t help, we still have to restart the WinCC server to recover the profibus net.
Please give me some hints.
Thank you in advance.
