Abstract

A communication network protocol among programable devices built-i manufacturing field, MAP (Manufacturing Automation Protocol), has to provide the job transfer service carrying out a lot of jobs distributively, and the MMS( manufacturing message specification) defines the above application layer protocol. In this paper user software required in job transfer was implemented. So as to provide each service with compatibility and extension, each module was designed according to the functions. A method is selected in double-assigning their domain and program applicable even in complex process, which loads and proceeds several programs sequentially. In order to confirm the logical validity of the designed protocol, local applying test is accomplished for the application layer of response station. Modelling the job flow process, each serice module is verified with the I/O primitives.
