Abstract; By introducing the design of common state viewer in the PLC host computer software, with the MODBUS protocol as example, the possible encountered problems in developing a uniform extensible host computer software platform for PLC， analyzed; a feasible design concept for host computer universal component is discussed; and a feasible solution is proposed in further. By fuly utilizing the advantages of.net modern developing language platform and object-oriented design concept, the configurable, reusable, extensible, low coupled, and universal host computer software for PLC can be implemented.
