Scope
Description
Portsmouth Water Ltd (PWL) currently communicates with its T4 type RTUs using the existing telemetry protocol. As existing has reached end-of-life with limited support available, PWL needs to use the Geo SCADA DNP3 WITS driver to communicate with each of the existing T4 type RTUs following their conversion from running the Proteus firmware to running the T4 DNP WITS firmware. Following on from a detailed study of the PWL database, and investigation into options, Schneider Electric Systems UK (SESUL) have identified a tool that will allow a user to select any Outstation on the existing PWL database for automatic conversion of its associated database objects to supported standards (DNP3 T4 WITS database objects) except for logic Charts. The scope of this delivery covers the design, development and testing of software tools to support the database conversion process, as well as the creation of Method Statements that detail the steps to be undertaken by SESUL and PWL on their site system.
The scope includes all 72 RTUs including addition RTUs (from critical sites) in the factory / testing phase and additional site engineering scope.
• Simple complexity Outstation - point counts less than 100 - 42 RTUs in total.
• Average complexity Outstation - point counts between 100 and 300 - 21 RTUs in total.
• Complex Outstation - point counts greater than 300 - 9 RTUs in total. The new scope of work is to migrate all 72 of these RTU over to WITS protocol using the tools and methodologies developed..
