I'm new on this forum and this is my first thread.
I have five powerflex 70's on the network connected to the DeviceNet scanner module 1747 SDN. The third powerflex 70 shows up an error 75 - Port 5 Adapter.
After i reset the error the powerflex runs for a while and than it happens again. Sometimes it happens to 2nd, 4th and 5th powerflex, but mostly errors shows up on the 3rd one. It has never happened to the first powerflex. The communication card on each powerflex is 20-COMM-D.
What causes that problem? I don't want to upgrade any firmware and/or start replacing anything, unless it is realy neccessary.
Thanks in advance.
