Hi, We have the same problem with our unit. The SF led for CPU 315-2DP remains lit and the BUSF led starts flashing. CPUs linked to a ET200s via profibus and to an OP27 via MPI. The ET200s controls around 20 DS-x motor starters. The problem is that ther e is no communication with this profibus linked ET200s. The BUSF led on both CPU and ET200s is flashing. We have done the following- repalce PLC with a new one. replace ET200s with a new one. change profibus connectors and cable with a new one. Still the problem isnt solved. I am attaching diagnostics of both CPU and ET200s. One more thing, the problem started with one of the DS-x starters. The DS-x starters are linked to a number of motors used to pump chemicals into the mixing tank. One of the DS-x starters had no SF Led when the problem was reported, while all others had their SF led on and the ET200s SF and BUSF leds on. We replaced the unlit DS-x with a new one, but a different order number( 6es7-etc etc). The damaged one was rated 6.3A and the new one we fixed 3.2A. I checked in the hardware configuration that the order number of all DS-x had to be entered before programming.I havent changed the order number to the new ones order number. Could that be the problem?
