Other AbstractThe invention relates to a method for EPA (Ethernet for Plant Automation) to FFH1 protocol conversion and scheduling, comprising the following steps of: establishing a hardware device comprising an EPA controller and an FFH1 module; running an EPA protocol stack on the EPA controller, and running an FFH1 protocol stack on the FFH1 module; running protocol conversion software in the EPA controller to implement protocol conversion from the EPA protocol stack to the FFH1 protocol stack; and running uniform scheduling software in the EPA controller to implement uniform scheduling from EPA to FFH1. The method ensures bidirectional transmission of data from EPA to FFH1, implements data stream conversion from EPA to FF and data stream conversion from FF to EPA, and implements service level mapping, has real-time property and universality, and can establish a control network with multiple structures mainly including EPA or FFH1 and set better compatibility.
