Ethernet Programmable Fieldbus Controller

Nov. 18, 2010
WAGO Corporation's high-speed 750-881 "ETHERNET 2.0" Programmable Fieldbus Controller processes 1000 instructions/235 µS.

The first from WAGO's upcoming "ETHERNET 2.0" line, 750-881 provides significant amounts of memory for PLC programs and Web applications, as well as an integrated dual-port Ethernet Switch. To keep pace, independent Ethernet ports respond in 1ms, transmitting real-time information to production and enterprise management.

The 750-881 PFC interfaces with standard network protocols, including unique support for both EtherNet I/P and MODBUS TCP. The Ethernet switch streamlines costs and system footprint by facilitating a line topology for fieldbus wiring, eliminating additional switches and hubs. An onboard DIP switch configures the last octet of IP address/assignment, expediting commissioning.

Keys to the 750-881's high-frequency processing are a 32-bit CPU and 1Mbyte of program memory. A 2Mbyte Fast File System supervises both a Web-Based Management System and substantial data logging. E-mail capability (updates/alarms) is also provided for authorized personnel. 750-881's standard CoDeSys V2 programming environment is IEC 61131 compatible, and features all five programming languages. The PFC supports up to 250 I/O modules, and allows users to tailor solutions from the 400+ analog, digital and specialty modules in the WAGO-I/O-SYSTEM.

The 750-881's new housing design departs from WAGO's traditional architecture. The slotted housing optimizes heat dissipation while maintaining a 0°C-+55°C operating temperature range and IP20 rating. Certifications include UL 508, cUL, GL and CE.

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.
