Traditionally, engineers have to arrange the slave IDs of all the Modbus serial devices when using multiple ports of Modbus-serial-to-Modbus-TCP gateways because it is restrained by only one TCP, connection with a slave ID range from 1 to 254. However, this is becoming a nightmare for engineers due to the increasing complexity of field devices, especially when dealing with an extension project. With the Moxa MGate MB3000 series, each serial port can be segmented by a dedicated TCP port, or an IP address, to create an independent connection to avoid slave ID conflicts.
