values of ON/OFF information to be sent to the master node.
3)
Set Auto Configuration Request (Y15) and Request for Saving
Parameters to Flash ROM (Y17) to OFF.
4)
When I/O Communication Request (Y11) is set to ON, the parameters
are checked.
5)
When the parameter check is succeeded, I/O communication with the
master node is started and I/O Communicating (X01) is set to ON.
Note that, until receiving an I/O communication request from the
master node, the module waits for connection establishment.
• Data sent from the master node are stored in Slave Function
Receive Data (address: 0B00
• The ON/OFF information to be sent to the master node is set in
Slave Function Transmit Data (address: 0C00
6)
If the parameter check has failed, the ERR. LED lights up and Error
Set Signal for Slave Function (X08) is set to ON. At this time, I/O
Communicating (X01) is not set to ON.
Check the error code in Error Information for Slave Function (address:
0601
), and take corrective actions.

7) Setting I/O Communication Request (Y11) to OFF stops I/O
communication with the master node, causing I/O Communicating
(X01) to turn OFF.
