Abstract
A cell controlling computer is interfaced to a group of station-level computers through an access machine which stores a database of data that is continually being updated from the station-level computers in response to conditions on machines and industrial process equipment. The access machine communicates with the station-level computers using messages addressed to each respective station. The access machine communicates with the cell controlling computer through database operations messages that allow data to be communicated for many stations at once. During on-line reconfiguration, new data items in the station-level computers can be added to the database in the access machine using other database operations messages.
