Profibus Interface CI541 stop working
We use CI541V1 module in AC450 controller as Proibus Master. At the moment are 6 slaves added. The total cable length is aprox. 50 m, Bus Parameters:
All slaves work well, but after some time (one or two days) the master stops with error and you have to reset the board. This is unfortunearily not possible by program, you have to set IMPL=0 and IMPL=1 on the database element or pull/put in the subrack. After this all is fine again.
I have set a repeater direkt on the profibus line on the board, it does not make a difference.
Is there a way or workarond to reset the board by programm or any automatic procedure?
Any other suggestion?
