Hi,
About a month ago, my KRC4 started reporting a couple "Safe device CIB Safety Module (SION-CIB): Error at input 6/7" error messages. The errors always happened while the robot was running overnight and they cleared after I rebooted the controller. I had not seen the errors for several weeks, but a couple days ago, the errors returned, but now wont clear after power cycle. I am jumping all the safety interfaces in the X11 connector except for the external estop. I checked all the pins with a multimeter on the X311 connector on the CIB board to make sure everything was jumpered as expected. I am using SafeOperation but only for workspace monitoring such that the robot stops at safety boundaries.
Similar to the issue here: CIB safe module (SION-CIB) error at input 6&7
Thanks!
