Description

technical field

[0001] The invention relates to the field of automatic control, in particular to a wireless embedded controller based on the factory automation (EPA, Ethernet for Plant Automation) industrial Ethernet field bus. Background technique

[0002] At present, the field control system mainly adopts the distributed control system (DCS). DCS uses one or more control units to control multiple loops, and its control part is distributed to some control boards, and each control board has one or more loops. In the process of forming the DCS system, due to the influence of the defect of system closure in the early stage of the computer system, the products of each manufacturer formed their own systems, and the equipment of different manufacturers could not be interconnected together. This kind of dedicated network is difficult to achieve interchangeability. There are many difficulties in interoperating and forming a network system for wider information sharing.
