Hello. I need som help
I`m commissining a Siemens ET200S I\O rack with profibus communication between a S7-400.
And heres the problem:
When I download the project the ET200S DI\AI and DO modules works just fine.
But when I disconnect the power(24V) to the ET200S-IM and connect it back I just get "BF"(BUS-FAULT)on ET200S-IM.
Then I must emty the PLC and download the project again to re-establish profibus connection.
I hope some off you could have an answar
PS: I`m not an experienced programer sow, pleas use esay explanation.
