Save the following parameters to the flash ROM in advance.
• Parameters for Slave Function (address: 060E
• Auto Communication Start Setting (address: 0631

When the power is turned ON, parameters saved in the flash ROM is
loaded into the buffer memory automatically.
Module Ready (X0F) is set to ON, and the parameters are checked.
3)
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

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.
