Abstract
This paper describes the design and implementation of the Glue Logic, which is intended to be an infrastructural element integrated into the Programming/Execution Environment in FA Control Systems. The Glue Logic coordinates multiple application processes by means of message passing. Using this system, users can easily implement data-sharing and task-interlocking amongst multiple application programs. Furthermore, this system includes event notification and condition monitoring features in order to eliminate the need for data polling. In this paper, the requirements of glue logic are discussed first, then the structure of glue logic is presented. Finally, implementation of the glue logic is described.
