The server connects to devices via serial connections, single port Allen-Bradley 1784- PKTX PCI cards and Ethernet connections, representing true “universal connectivity” for connecting PLCs. The Server includes time-saving features not found in other drivers, says the vendor, including automatic discovery of devices over serial and PKTX cards; automatic configuration of devices; competitive system expansion; loading of device configuration files like .l5k, .pc5, and .slc; serial automation configuration of connection types; automatic tag generation for each device; and device-level redundancy support through fail-over channels.
