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
