WAGO Corp.'s high-speed 750-881 ETHERNET 2.0
Programmable Fieldbus Controller processes 1,000
Î¼S. 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
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.
750-881's new housing design departs from WAGO's traditional architecture. The slotted
housing optimizes heat dissipation while maintaining a 0 to 55C operating
temperature range and IP20 rating. Certifications include UL
508, cUL, GL and CE.
George Leopold's talk at last week's Design & Manufacturing Minneapolis helped restore astronaut and engineer Gus Grissom's role in the beginnings of NASA, and outlined how Grissom played a pivotal role in winning the Space Race.
