Description
Most plants already have the data. It is sitting in the PLCs, being overwritten every cycle. SCADA work is about deciding what is worth keeping, getting it out reliably, and presenting it so a decision can be made from it.
Getting the data out
Reading from existing controllers over their native protocols or OPC UA, without rewriting the machine programs where that can be avoided. Where a machine program does need to change, the change is limited to publishing values — the control logic stays untouched.
Overviews and trends
A plant overview should answer one question in one glance: what is running, what has stopped, and what is about to become a problem. Trends are configured for the values that actually get investigated later — cycle times, temperatures, pressures, reject counts — with enough history to compare a bad shift against a good one.
Reports
Production counts, downtime by reason and alarm frequency exported on a schedule, in a format that opens in the tools your team already uses. A report nobody opens is not worth building, so the reporting scope is agreed before development starts.
