Object-Oriented Execution and Monitoring of Industrial Control Logic for Automated Manufacturing System

摘要

In order to cope with re-configurability of manufacturing system, it is quintessential to test industrial control logic rapidly and easily in the design-time, and monitor operational behavior correctly in the run-time of automated manufacturing system. Proposed integrated model for virtual prototyping and operational monitoring of industrial control logic is to improve limitations of current ladder programming practices and general discrete event simulation method. Each plant layout model using HMI package and object-oriented control logic model is designed independently and is executed simultaneously in integrated manner to reflect design practices of automation system in the design time. After the physical installation, layout model constructed in the design time is reused for operational monitoring of system behavior during run time with slight modifications.
