• Even though 'I/O communication request' (Y11) is turned on while 'Auto configuration request' (Y15) or
'Request for saving/clearing parameters to Flash ROM' (Y17) is on, 'I/O communicating' (X01) does not turn
on. After the output signal turns off, turn off and on 'I/O communication request' (Y11) again.
• To stop the I/O communication, set 'I/O communication request' (Y11) and reset it after 200ms or longer.
■When starting the I/O communication automatically at power-on
For auto communication, set 'Auto communication start setting' (Un\G1585) to "Start".
• When the power is turned on, 'Module READY' (X0F) turns on and the parameter is checked.
• When the parameter check normally completes, the I/O communication with each slave node starts and 'I/O
communicating' (X01) turns on.
• When the parameter check abnormally completes, the ERR LED turns on and 'Master function error set signal' (X03) turns
on. 'I/O communicating' (X01) does not turn on at this time. For details on 'Master function error set signal' (X03), refer to
the following.
