Starting the I/O communication automatically at power-on
For auto communications, set 'Auto communication start setting' (Un\G1585) to "Start".

(1) Parameter check
(2) MOV/FROM instruction
(3) MOV/TO instruction
 Set the following parameters in advance.
• 'Master function parameters' (Un\G468 to Un\G975)
• 'Auto communication start setting' (Un\G1585)
 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.
• The input status from each slave node is stored in 'Master function receive data (Un\G1792 to Un\G2047).
• Set the ON/OFF information to each slave node in 'Master function transmit data' (Un\G2304 to Un\G2559).
 When the parameter check abnormally completes, an error occurs and 'Master function error set signal' (X03) turns on. 'I/O communicating' (X01) does not
turn on at this time. Check the error code with the module diagnostics, 'Master function error information' (Un\G433), or 'Master function communication error
information' (Un\G1152), and correct the error.
 When 'I/O communication signal request' (Y11) turns on and off, the I/O communication with each slave node stops and 'I/O communicating' (X01) turns off.
