Safety System Fault C192A16 & C192A18 |

Dear professionals and robotics enthusiasts,
Please I need your help! Recently, our UR is frequently showing a safety message (SafetyB: C192A16: Safety system fault: Safety output failed). It always shows randomly and it has largely affected the production process. Based on the log, the error code C192A16 always comes together with C192A18 (SafetyA: C192A18: Safety system fault: The other safety processor is in fault.).
We couldn't find any related solution online except referring to the manual. So far there is no short circuit found in the system. Someone who is experienced please help because we are quite new to the robot. Any advice is welcome to at least know where and how to start in solving this problem.
Much appreciated!
Thanks.

The problem is the robot is configured to run a sequence of processes and it only happens in a particular configuration (if it happened). So I think unplugging the IO blocks and testing each would be infeasible in our case as the robot is running in the production.
May I ask if the intermittent short in the IO wiring is only occurring at the connection points between wires? Or there might be some of the wires themselves are broken?
Thanks.
We also had instances with broken/cut cables causing the issue.
Besides, we just would like to narrow down the scope of the investigation. So would you think it is possible that the short circuit occurs from the internal system of the robot itself?
Thanks.
