Groups and Items

FactorySQL configuration is done with standard Groups. This unit of configuration can morph from a historical logger, real-time status and control synchronizer, downtime tracker, recipe manager, etc.[4] The group configuration defines the database connection, table, timing options, triggering options, and "direction". Direction defines whether read or write operations come from or go to the OPC server from the SQL database. "Bidirectional" allows a change from either side to be written to the other. Groups contain Items. Items are dragged from an OPC browsing tree or manually created. Each item represents a fully qualified OPC path along with a column name in the SQL database. Items also contain scaling options, OPC information, and other modes of operation.
