These gateways can be user-configured to support multiple Ethernet and serial protocols such as EtherNet/IP, ModbusTCP, Modbus and DF1. They also support multiple channels of Allen-Bradley Remote I/O (RIO) or Data Highway Plus (DH+). These gateways can be used to bridge equipment between multiple vendors and also provide users of Rockwell PLCs and PACs an easy way to upgrade obsolete drives, robots, operator interfaces and other RIO or DH+ devices without requiring replacement or changes to the PLC or adding communication modules to a Logix PAC.
