3A01H to
3AFFH
Each of the following bits indicate an error.
3AH
Lower bits: Logic path A (0: no error, 1: with error)
• b0: Bit for input logic error
• b1: Bit for start function logic error
• b2: Bit for output logic error
• b3: Bit for bypass error
Upper bits: Logic path B (0: no error, 1: with error)
• b4: Bit for input logic error
• b5: Bit for start function logic error
• b6: Bit for output logic error
• b7: Bit for bypass error
Check the wiring of inputs for the corresponding logic paths.
3B01H I0/I1 synchronization
time/concurrence error
A synchronization time/concurrence error
occurred in I0/I1.
Inconsistency in the double input state is detected.
Turn the input signals I0/I1 OFF and ON again.
If the error is not resolved, check the wiring of the corresponding
input terminals.
3B02H I0/I1 process error A process error occurred in I0/I1. Inconsistency in the double input state is detected.
Turn the input signals I0/I1 OFF and ON again.
If the error is not resolved, check the wiring of the corresponding
input terminals.
3B03H I0/I1 cross-circuit error A cross-circuit error occurred in I0/I1. A cross-circuit is detected in the double input state.
