Modbus Serial to Ethernet Gateway

BUSWARE Direct, the factory-direct-to-customer business unit of Action Instruments, announces the availability of a Modbus Serial to Modbus/TCP gateway. The gateway allows up to 32 Modbus slave devices, interconnected with a standard 2-wire, RS-485 serial bus, to be accessed at a single, user-defined designated IP address using the open standard Modbus/TCP protocol. The DC-Powered Model EI03-1101 is designed to operate in extreme environments from minus 40 to 85 degrees Celsius and is designed for Class 1, Division 2 (EN50021 Zone 2) hazardous locations.

Ethernet has established itself as the market leader in industrial field bus applications. The BUSWARE Direct Modbus Serial to Ethernet Gateway provides an easy, cost-effective way to bring legacy instruments onto the Ethernet backbone. Just as virtually every PC, PLC, and DCS system supports Modbus-RTU and Modbus-ASCII serial protocols, so too is the Modbus/TCP standard being accepted as the most commonly used industrial Ethernet protocol. Mike Adelman, Product Manager for BUSWARE Direct describes some of the applications for the gateway: "There is a tremendous variety of industrial devices from single loop controllers to chart recorders to weigh scales with Modbus serial communications capabilities built into them. This gateway allows all of those instruments to be interconnected, monitored and controlled using a plant's Ethernet infrastructure."

The gateway measures less than 3" tall and 5" wide and can be mounted on standard DIN rail or directly onto a panel.
