Protocol gateways connect Modbus devices to Profinet

March 2018 Fieldbus & Industrial Networking

Moxa’s newly launched MGate 5103 and MGate 5111 industrial protocol gateways enable fast and easy protocol conversions between Modbus devices and Profinet or Profibus-based scada systems and PLCs. These stand-alone protocol gateways also allow a distributed network architecture that maximises flexibility and scalability. In addition, they also extend the lifetime of field devices, consequently reducing costs. The gateways convert a variety of protocols to Profinet or Profibus, and furthermore, they also help integrate Ethernet/IP PLCs into such systems.

Fast and easy configuration

“Configuration is often an arduous task, especially when adding PLCs for protocol conversion as it requires extensive coding,” says KS Hsu, a product manager at Moxa. “Therefore, we spend a lot of design time making sure that our protocol gateways are easy to set up and use. The MGate 5103 and 5111 have a user-friendly interface with quickly set up protocol conversion routines for most applications, doing away with tasks such as implementing detailed parameter configurations one by one. In addition, with Moxa’s configuration wizard, users can easily access protocol conversion modes and finish the configuration in five easy steps.”

Easy troubleshooting to reduce maintenance efforts

Moxa’s two new protocol gateways provide a variety of powerful built-in troubleshooting tools, including protocol diagnostics and traffic monitoring, which offer engineers a shortcut to find the root cause of a network breakdown. In addition, the status monitoring and fault protection functions help to reduce downtime. The status monitoring function alerts the scada system when a Modbus slave device is not responding, and fault protection prevents incorrect actions downstream if the upstream connection is lost.
