This slide presentation outlines Structured Testing as a methodology that uses standardizedprogramming and testing procedures toefficiently demonstrate compliance with Standards, andaccuracy of I/O addressing parameters from thePLC code to HMI data links prior to fieldinstallation. Testing is based upon:uniform project programming standards;clear / quantifiable test objectives; and,dynamic testing in safe, stable environments. CDM developed structuredtestingto create project efficiency for a complexcontrol system implementation, toreduce down-time, errors, and other problemsin Automation strategy implementation,to integrate into existing On-Line systems withminimal scheduled plant interruptions, and toprevent unintentional process interruptions. The presentation outlines topics that cover: automation upgrade overview and issues; key components of the structured solution; developing programming standards; tag naming standards; Register Mapping Standards -Numbering Breakdown; PLC Programming - RegisterStandards; PLC Programming OrganizationStandard; HMI Animation Standards; The Structured Solution - Develop Standard Testing Procedures; Benefits of structured testingapproach; and, lessons learned. Includes tables.
