OPC cycle time analyser

Abstract

[Abstract]: Variations in equipment cycle times can have a significant effect on the output of modern assembly lines. In an effort to identify and act accordingly when these variations occur, the development of a software application to analyse equipment cycle time via OPC is investigated in this project. Manufacturing organisations continuously seek improvements in equipment performance and output. A common improvement made is the reduction of equipment cycle time, this provides an increase in output for a relatively small capital outlay. These improvements remain relatively unchecked and variations in cycle time due to numerous factors continue to influence equipment performance. An equipment cycle time analyser can be used to monitor and report variations in cycle time. The resulting information can be used to predict equipment failures and allow maintenance departments to plan corrective actions. This analyser tool can also be used by engineering departments for analysing equipment cycle time during cycle time improvement projects and new equipment installation. Currently the development of the cycle time analyser system is at a stage where the cycle time of equipment can be monitored using OPC as a means of communication. Additionally a Microsoft Excel application is available which can import the data recorded by the cycle time analyser software and display a step time diagram of a complete equipment cycle.
