Germantown, WI – September 2008 – Integrated Ethernet switch functionality enables WAGO's new 750-871 ETHERNET TCP/IP 2-Port Programmable Fieldbus Controller to optimize networking capabilities while streamlining associated costs. The 750-871 is easily integrated into existing Ethernet networks while minimizing the overall number of components. The controller can link the WAGO-I/O-SYSTEM to the ETHERNET fieldbus and the dual RJ-45 Fieldbus ports daisychain up to 20 devices — each segment may be up to 100m long — within one series.

"Although Ethernet networks offer excellent flexibility, this often comes at the price of additional components," said Mark DeCramer, Product Manager – WAGO-I/O-SYSTEM. "With the 750-871's integration of switches into a PLC, users can provide PLC control to local and networked devices without incurring additional component costs."

The controller is programmable in accordance with IEC 61131-3 and also features an integrated DIP switch that may be used for IP address assignment.

Well-Networked Controller:

The 750-871's compatibility with several protocols makes it an ideal system addition. For instance, the 750-871 can utilize MODBUS/TCP and EtherNet/IP for data acquisition or control, and may utilize one of several protocols (HTTP, BootP, DHCP, DNS, SNTP, FTP, SNMP and SMTP) for system management and diagnostics. The 750-871 permits data transmission rates of 10/100 Mbits/s, contains 512 KB of program memory, 256 KB of data memory and 24 KB retentive memory. A battery-backed, real-time clock and 32-bit multi-tasking CPU provide additional reliability and support for a wide variety of applications. HTML pages can be conveniently placed on the 750-871's internal server for use in Web-based applications.

WAGO is the leader in spring pressure connection technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products: DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; the WAGO-I/O-SYSTEM and more.
