I/O: Media Redundancy Controller

April 15, 2011
The 750-882 Ethernet 2.0 Media Redundancy Controller offers two redundant networks via independent Ethernet interfaces.
With the cost of downtime at an automotive plant estimated at $22,000/minute, redundancy is a fundamental discipline for all manufacturing applications. This I-O system achieves simultaneous redundancy by operating over two networks, accessible via two different IP addresses and MAC (Media Access Control) IDs. Featuring 10/100 Ethernet speed and RoHS compliant, the two networks can also be configured for non-redundancy applications and addressed separately for intra-network data exchange. An onboard DIP (dual in-line package) switch streamlines IP address assignment.   The system utilizes TCP/IP stacks, a multitasking IEC 61131 runtime system and MODBUS/TCP with rapid response, the company says.  Other features for the IP20 rated I-O system include 1MB program memory, a 2MB Fast File System, additional libraries and redundancy modes.  Wago Corp. www.wago.us For more specs on the product above, click here.
