Wago controller with Ethernet 2.0
August 2011
Fieldbus & Industrial Networking
Wago’s 750-881 Ethernet 2.0 programmable fieldbus controller is able to provide sufficient memory for PLC programs and web applications, as well as an integrated dual port Ethernet switch. The high-speed controller processes 1000 instructions/235 μS. 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 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, which facilitates commissioning. The 750-881 is able to achieve high frequency processing using a 32 bit CPU and 1 Mb of program memory. A 2 Mb Fast File System supervises both a web-based management system and substantial data-logging. An e-mail capability with updates and alarms is also provided.
The 750-881’s standard Codesys V2 programming environment is IEC 61131 compatible and features all five programming languages. The controller supports up to 250 I/O modules and allows users to tailor solutions from more than 400 analogue, digital and specialty modules in the WAGO-I/O-System.
The 750-881’s new slotted housing design with IP20 rating optimises heat dissipation while maintaining a 0 to 55°C operating temperature range. Certifications include UL 508, cUL, GL and CE.
