Diagnoses the duplicated input device status are matched.
This function diagnoses that the input circuit and the external connecting machine
is not fixing when condition is ON.
This function diagnoses the output circuit and the external connecting machine is
not fixing when condition is ON.
When turning on the power, turn each input device on and off individually several
times to diagnose fixing.
