I have error 1001 (EMERGENCY STOP SWITCH ON) in Fanuc series oi-MC Controller.
This error came from input X8.7 which is always read as zero in the controller but it is on in the I/O Board.
I checked the cables, the I/O Board and the I/O modules but all seems OK.
I also noticed that the controller can't see some inputs X.
Could it be a parameter problem, cause I tried some parameters from other machines (same model).
Please help, thanks.
