Modbus gateway devices connect to Ethernet

The MESP211 by B&B Electronics converts Modbus ASCII or RTU signals to TCP Ethernet and can control Modbus devices on LAN or WAN Ethernet.


The MESP211 by B&B Electronics converts Modbus ASCII or RTU signals to TCP Ethernet and is able to control Modbus devices on LAN or WAN Ethernet. Courtesy: B&B ElectronicsB&B Electronics' MESP211 is a compact gateway designed to convert Modbus ASCII or Modbus RTU serial signals into Modbus TCP Ethernet. The MESP211 connects Modbus devices to Ethernet networks to monitor and control Modbus devices from anywhere on the Ethernet LAN or WAN, and flexible configuration allows serial and Ethernet, Masters and Slaves. Designed for harsh environments and cramped spaces, the compact gateway features a wide operating temperature, Heavy Industrial specifications (61000-6-2 EMC level 3 for harsh environments; IEC60068-2-27 for shock, -6 for vibration and -32 for free fall), and a rugged IP30 metal case that is panel (standard) or DIN rail mountable (with optional adapters).

Applications include temperature control equipment, HVAC systems, industrial PLCs, power sub-metering, and communications to solar trackers and inverters.

B&B Electronics’ Vlinx Manager Software installs on the user’s PC and lets them remotely manage the MESP211 over a LAN or WAN via the built-in web server. Users can take advantage of Modbus messaging priority control and view messaging status in real time via the built-in traffic monitor.

The one-port MESP211 Modbus Gateway works with RS-232/422/485 serial signals and is available in two models: the MESP211D offers a DB9 Male connector while the MESP211T offers a Terminal Block connector.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
