Modbus Gateway
Figure 1-1 Modbus Gateway
Devices that use Modbus/TCP cannot directly communicate with devices that use
serial line Modbus protocols. Because not only the physical interfaces are different
but also the protocols are not compatible. If you want to implement the
communication, you need a device that convert and route data of both sides. We call
that kind of device Modbus Gateway.
