Hello everyone,
We have a AB 1756 L55m13 controller and profibus adapter sst-pfb-clx. The adapter is connected to six Vfds (all Siemenes midimaster and micro master). We had changed profibus cables and connectors.Ever since we changed one of the VFd is blinking green and the profibus adapter has red light on sys led. I checked the manual it says error in communicating with one of the slaves.The only way we can get this working is powering down all vfd and plc and powering up again. Some times it runs for 2 days without any problems but again the problem shows up. What could be the problem. Please help
