Posted 13 Sep 2019 Dear all, I have a problem with my hydraulic drilling machine ( Furukawa HCR1500 EDII), that is equipped with CJ1M-CPU11 PLC. When it is working, it often stops because of 80CF/0F0F error . But when I remove all cables, it is normal. I change many PLCs, but get the same errors. Pls help me. Thank you.
