Abstract
This paper proposes Plant Motion Control Software (PMCS) development process. This process uses 2 kinds of software components (for requirement and implementation) and Z language (to describe design information). PMCS can be standardized, and design information can be transmitted accurately with using the software components and Z language. To adapt proposed process, it would be trace PMCS functions from requirement specification to PMCS. Consequently, PMCS that is adapted to the user requirement, would be developed.
