WAGO: Ethernet Media Redundancy Controller
Ethernet redundancy controller.
Germantown, WI — WAGO Corporation's 750-882 Ethernet 2.0 Media Redundancy Controller provides two redundant networks via independent Ethernet interfaces. This enables communication with a redundant network,which is suitable for applications requiring high network and system availability (e.g., shipbuilding), 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, such as from shop floor machinery to top floor Manufacturing Enterprise System.

Part of the new platform, 750-882 provides high-speed processing: 1000 instructions <235µs and accommodates HTTP, BootP, DHCP, DNS and FTP. The 750-882 uses an industry-proven TCP/IP-stack, multitasking IEC61131 runtime system and MODBUS/TCP with rapid response.

750-882 includes: 1MB program memory (program code), 512kb data and 32kb retain memory. A 2MB 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.
