I found that a smart cable broke. Students were getting motor error messages on port 1-3. When a motor was plugged into port 1 on a drive a bot. When I replaced the cable everything worked. When I used the old cable on a different brain the old error messages showed up again.
- Is there a toot or device to test the smart cables?
- Can one wire go bad and cause errors like I have seen?
Thank you
