Moxa launches Ethernet to RS-232/422/485 gateway

Many industrial devices, such as PLCs, DCSs, HMIs, instruments, and meters, use Modbus as their communication standard: this Modbus gateway links to RS-232/422/485 devices and Ethernet devices

Many industrial 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.

For Modbus protocol conversions, it is necessary to define a Master and Slave device, but unlike other Modbus Gateways, NPort 6110 allows users to configure Master/Slave for both the Ethernet and serial sides.

Extra address mapping and exception parameters are supplied to ensure that most situations can be handled.

NPort 6110 is powerful yet very easy to use, providing a Windows utility for easy setup and traffic monitoring.

An intuitive Windows utility automatically searches for all available NPort 6110 units on the LAN.

Traffic monitoring within the utility helps you troubleshoot any Modbus communication problem, such as connection status check, or address translation error check.
