Accessing process data from your facility’s data historian shouldn’t be difficult. PlantESP control monitoring software makes connecting easy by using common data communications and querying protocols such as OPC-HDA, OLE-DB, ODBC, and SQL Queries. PlantESP is unique in that it can also connect direct to most historians using their proprietary connectors such as the PI-SDK for OSIsoft’s PI data historian, Proficy-API for GE Proficy Historian.
The PlantESP server links directly to your facility’s data historian. It operates as a one-way street, accessing data for the sole purpose of analysis and never pushing data back to or altering data in the historian.
