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.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.
“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.”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.
