Abstract
This paper describes a design and an implementation of the glue logic, which is intended to be an infrastructural element integrated in the Programming/Execution Environment for 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 among multiple application programs. Furthermore, this system includes event notification and condition monitoring features in order to eliminate needs of data polling. In this paper, the requirements for the glue logic are discussed at first, then the structure of the glue logic is presented. Lastly, the implementation of the glue logic is described.
