Temecula, Calif.— Opto 22 unveiled on March 15 one of the world's first industrial I/O systems with a built-in web server. Designed to work with Opto 22's new Snap Ethernet I/O, Snap-B3000-Enet allows any browser to connect directly to analog and digital I/O in real time. Because users only need a browser, no special software is required to read and write data using Snap-B3000-Enet.

Built-in web pages provide I/O configuration pages, analog I/O values, digital I/O status, digital input counter values, analog gain and offset data, streaming data configuration, help screens, and more at the I/O level. Snap-B3000-Enet can serve web pages, while its brain is simultaneously operating in a data acquisition and control mode, without performance degradation.

Snap Ethernet I/O uses pure TCP/IP communications, which allow its web server to work across the Internet as well as any local Ethernet network. Snap Ethernet I/O's brain also features push technology that streams data at user-defined intervals from it's web server to client applications. Other features include IP filtering, secure logons with password encryption, and configurable ports. Users can examine five demonstration panels of Snap Ethernet I/O at www.internetio.com.

Opto 22 also announced OLE for Process Control (OPC) support and Modbus/TCP support for Snap Ethernet I/O, which aids integration with third-party OPC and Modbus-enabled clients respectively. The company also released Snap Ethernet I/O's free driver support for Linux operating system, which joins its earlier Pamux for Linux driver for parallel bus I/O connectivity.
