Hi colleagues,
There is an issue with the profinet protocol which reports status prepare for no apparent reason, consequently all communication seems to be stopped with the control. I had this problem earlier (3-4 months ago), and solved it by upgrading from firmware 0308.02 to 0308.03, initially seemed to had solved it but it just came back from the dead.
I know there is an recent firmware version 0308.04, didn't tested it though.
Any thoughts on this?
