Look Ma No Faceplates: Benefits of In Situ Modification of Set Point and Output

This presentation illustrates the need and solution for operators viewing and making changes to set points and outputs in context. It shows the penalty and risks of operators shifting focus to faceplates and performing other window management tasks when trying to operate an industrial process. In-situ modification improves the speed of operator response, reduces entry errors and operator loading. For the industrial process, this means less spurious trips due to operator entry and more reliable and efficient plant operation. The presentation will cover how to incorporate items normally displayed in the faceplate directly into the operator display. The illustrated examples will be running ProSys' Interface Dynamics display library, but concepts in presentation are applicable to any industrial HMI and can be achieved in almost any control system.
