Research and Implementation of Interoperate Technology Between EPA and FF H1 Devices

Aimed at the interconnection and interoperability between EPA and FF fieldbus devices,we presented a system model to achieve the interoperability of this two protocols' devices,through analyzing the device description language and function block of EPA and FF H1 protocols.With the protocol conversion ability of gateway,EPA host computer can oversee running state of FF H1 devices, and can achieve different network segment configuration to exchange messages with each other.In the end,the system implementation results show that,the system can realize the designed functions between EPA and FF H1 network segments,and has perfect function. This system can promote EPA's market application.
