Media redundancy controller

Blending automation and IT protocols, WAGO Corporation’s new 750-885 Media Redundancy Controller provides applications with network redundancy and greater data processing. The ETHERNET 2.0 750-885 PLC features two redundant networks backed by dual, independent Ethernet interfaces and 1MB of data memory. SD Card provides up to 32GB of extra memory for back-up-and-restore, file transfer and time-stamping/data-logging. A dual LAN, 750-885’s two Ethernet ports permit operation over independent networks and paths, which are accessible via different IP addresses and MAC IDs. If Path 1 fails (e.g., broken cable), Path 2 resumes communication. This is critical — and often mandatory — in engine rooms or building security. If redundancy is not required, 750-885 separates data between different networks, e.g., between machine and office.
