SoftPLC gateways are designed to be user-configured to support a mix of Ethernet and serial protocols such as Ethernet/IP, Modbus TCP, Modbus and DF1. They 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 Automation PLCs/PACs a way to upgrade obsolete drives, robots, operator interfaces and other Remote I/O (RIO) or Data Highway Plus (DH+) devices without requiring replacement or changes to the PLC or adding communication modules to a Logix PAC.
