Market Trend

A top priority for many of today's applications is providing more services with less energy consumption. Because of this need, energy management software and SCADA systems are in wide use. For newer trends, such as the Industrial Internet of Things (IIoT), Industry 4.0, smart grids, etc., strong emphasis is placed on energy efficiency because of the benefits it brings to users. Devices such as power meters, UPSs, ATS, and protection relays are essential to achieve satisfactory energy efficiency levels. Most of these devices support the Modbus protocol, which usually means Modbus RTU because of its simplicity and cost-effectiveness. However, since infrastructures are now Ethernet based, Modbus TCP must also be used. For this reason, many users turn to Modbus gateways, since the gateways can easily perform conversions between Modbus TCP and Modbus RTU.

1, 2, and 4-port standard serial-to-Ethernet Modbus gateways

Modbus-serial-to-Modbus-TCP conversion in 3 easy steps
Accessible by up to 256 TCP master connections
10x faster performance with active polling (MB3660)
Protocol analyzer for quick troubleshooting

Simplify Hardware System Design     Make SCADA Configuration More Flexible     Reduce Commissioning Time
The MGate gateway's cascade feature requires fewer Ethernet ports, reduces cabling costs, and saves you a lot of time and effort setting up your system. In addition, the serial redirector function allows a Modbus RTU and Modbus TCP master to operate simultaneously, and communicate with serial slaves at the same time. MGate gateways can be configured to operate in a number of different modes depending on the application: transparent mode for typical usage, agent mode to decrease Ethernet traffic, and intelligent mode to reduce latency. These modes are suitable for retrofit, new, and small- or large-scale Modbus networks. Moxa’s MGate gateways can be configured with a user-friendly web console that walks you through the entire setup process in just few minutes. No additional software is required. A Windows-based utility with an attractive user interface is included at no additional charge for those who prefer configuring their products offline.

White Paper: How to Architect Your Systems to Get the Most Out of Your Modbus Devices

The migration of all industrial applications to Ethernet is unquestioned. But, before network engineers can inch closer toward all-systems-go, they need to overcome several challenges. The most pressing one is to ensure that there is no breakdown in communication between serial devices and SCADA hosts. It is no secret that plenty of solutions are available on the market. The immediate question is which solution fits your network’s requirements the best.

In this white paper, we will look at four challenges that arise when linking up Modbus-supported devices to SCADA systems. We will also provide solutions for different scenarios to address your concerns.
