What is the issue that has caused the back-end PLC2-M7000 to detect material in the work area? How can the status of the work area machine code for KM-ASSYH4-05 error id of 161 be confirmed?
The solution for the error would be to visually inspect the work area to confirm if there is any material present. Once the area is clear, the PLC can be restarted, and the error should no longer occur.
