SMG-5420 User Manual Ver. 1.6 1.2 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. To facilitate communication between the two devices, an additional device is required to route the Modbus data from each device. -
