Hi everyone! I have a bus fault on my IM 153-1 and so with my S7-400 PLC. I alreadey replaced the IM 153-1, the bus connector and the profibus cable. It has the same address on the dip switch and the HW Config, also the part numbers configured on the HW Config is the same with the modules in the field. I have also tried to insert new IM 153-1 and configure it to the profibus network and delete the existing. Please see attached photos for the diagnostic buffer of the PLC and the module information of the IM 153-1. Any insights would be a big help. Thanks!
