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.

Posted 13 Sep 2019 khoi, 80CF is an I/O bus error. Check the interconnection of I/O modules. 0F0F is not showing in the manual. Please refer to manual W393 for further information. gtsuport Share this post Link to post Share on other sites
