METHOD FOR DESIGNING NETWORK CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To easily set up component ware by standardizing a display and editing method for data related to component ware by making it possible to access the component ware through a data access interface standardized for plural connected component ware. SOLUTION: Not only syntax appropriateness but also semantic appropriateness is required for connection between components. Restriction information included in each component itself includes not complete but considerably large part of semantic appropriateness. In the case of mutually connecting two components, mutual restricting conditions are checked. When an output side restricting condition is more severe than that of an input side restricting condition, connection processing is executed. When the former condition is not so severe, inter-component connection is rejected. When the procedure is inserted into a tool for connecting between components, a bug generated due to the contradiction of data to be transferred between components can be removed on the stage of Pos design.
