Multi-protocol fieldbus gateway moxa
Modbus RTU - Modbus TCP

Modbus is one of the most popular automation protocols in the world. Modbus protocol supports traditional RS-232/422/485 devices and newly developed Ethernet devices. Many industrail devices, such as PLCs, DCSs, HMIs, instruments, and meters, use Modbus as their communication standard. However, the Modbus protocol running over serial and Ethernet are so different that a communication gateway is needed as a bridge for integration. NPort 6110 supports one Ethernet and one software selectable RS-232/422/485 port that can connect with all kinds of Modbus devices. By translating Modbus/TCP (Ethernet) and Modbus/ASCII/RTU (Serial) protocols, a PLC with Ethernet can use the RS-232/422/485 interface to seamlessly communicate with instruments.
