Fieldbus Controller integrates Ethernet switch into PLC.
Press Release Summary:
Featuring integrated DIP switch, Model 750-871 Dual-Port Ethernet Controller can link WAGO-I/O-SYSTEM to ETHERNET fieldbus, while dual RJ-45 Fieldbus ports daisychain up to 20 devices. It uses MODBUS/TCP and EtherNet/IP for data acquisition/control, and may use 1 of several protocols (HTTP, BootP, DHCP, DNS, SNTP, FTP, SNMP, or SMTP) for system management. With data transmission rates of 10/100 Mbits/sec, unit includes 512 kB program memory, 256 kB data memory, and 24 kB retentive memory.
Original Press Release:
WAGO 750-871 Dual-Port Ethernet Controller Integrates Ethernet Switch into PLC
09/02/2008
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.
