April 14, 2011 – WAGO’s 750-882 Ethenet 2.0 Media Redundancy Controller provides two redundant networks via independent Ethenet interfaces. This enables communication with a redundant network — ideal for applications requiring high network and system availability or two independent networks. Simultaneous redundancy is achieved by operating 750-882 over two networks, which are accessible via two different IP addresses and MAC IDs. The independent ETHERNET ports permit redundant connection of two transmission paths.
If Port 1’s path fails (e.g., broken cable), Port 2 serves as an alternate.
If redundancy is not required, networks are addressed separately for intra-network data exchange, e.g., from shop floor machinery to top floor Manufacturing Enterprise System.
Part of WAGO’s Ethenet 2.0 platform, 750-882 provides high-speed processing — 1000 instructions < 235μS and accommodates HTTP, BootP, DHCP, DNS and FTP. 750-882 employs an industry-proven TCP/IP-stack, multitasking IEC61131 runtime system and MODBUS/TCP with rapid response. 750-882 includes: 1 MB program memory (program code), 512 Kb data and 32 Kb retain memory. A 2 MB Fast File System, additional libraries and redundancy modes complete the package.
An onboard DIP switch streamlines IP address assignment; the integrated Web server provides Web pages and remote access. IP20-rated 750-882 carries UL 508 and GL certifications. 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.
