If you want Master devices to communicate with each other, connect the Master devices to the same

subnet. This M-Link device works as a slave device. Modbus TCPIP server and client devices must have

fixed IP.

If you want to do the point transfer between devices, connect devices to the bus of the M-Link.

Add a device you want to write or read through the bus. Enter the IP address. You can read the device

points of another device. Make a point transfer.
