We have a robot with 8 programs, and it works well with all programs, but occasionally a parity error occurs when sending the program from the PLC.
Why might a parity error occasionally appear on a KRC2 when sending the program from the PLC?
Communication between the KRC2 and PLC is via digital I/O. The PLC's output cards and the KRC2's input cards have been changed.
Any additional points to review?
Thanks you so much.
