	The RFC 460R PLC from Phoenix Contact is a high-performance controller that has been extended to offer redundancy functionality. This redundancy functionality is vital for uninterrupted processes in complex systems and large plants. In order to integrate this product into EPICS environment, an EPICS Driver is developed. This driver is intended to connect a pair of RFC 460R redundant PLCs via TCP/IP to an EPICS IOC. In this paper, the communication mechanism, software implementation and the test results of a prototype system will be described.

This driver is intended to connect a pair of RFC 460R redundant PLCs via TCP/IP to an EPICS IOC.
