B&B Electronics has expanded its family of Vlinx Modbus Communications Gateways with the MESP211, a low-cost, 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 (3.1 x 0.9 x 2.0 in, 7.9 x 2.3 x 5.1 cm) gateway features a wide (-40 to 80°C) 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’ signature Vlinx Manager Software – the same advanced software that comes with the company’s higher-end Vlinx MESR900 and MESR400 Modbus Gateways – 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.
