3) OUTPUT IN AN ABNORMALITY
When an abnormality such like CPU error, STOP, time-out occurs at the PLC, the output signal of the 60C is maintained as
HOLD (no clearing output signal, keeping the value just before the abnormality).
When the PLC recovers to normal operation and the 60C receives new data, the output restarts changing.
