Having used many products it was decided in 1995 to develop our own SCADA system to fully cover our customer requirements. Packaged products fell short in some areas such as logging per cycle, data overwriting after 3 months, levels of access and graphing interrogation. Our first product was written in the Visual Basic 4 language with later upgrades in Visual Basic 5 & 6. The client response was encouraging and we began a full rewrite in 1998 using the C++ language. At present we are working on the C# .net version. The system was always designed to allow simple, password protected, operator access at the clients desired level and also to give engineers in depth information about the plant. In this way engineers can access critical items such as pump stop levels to allow a maximum output without harming plant components. Event logs and graphs can be annotated to permanently record events I.E. calibration of an instrument. In this way log and graph readings outside of the norm can be identified. Key Benefits
