Abstract:

A method is provided for managing information on a plant floor, and includes recording a definition file, such as an extended markup language (XML) schema, in a source device, and generating a plant floor event (PFE) message as a bit array or string array. The PFE message transfers from the source device to a host device or other appliance. The method then includes executing at least one action in response to the PFE message. A system is also provided for managing information on a plant floor, and includes a PLC that generates a PFE message as a bit or string array. The system includes an alarm database, and automatically propagates the PFE message upward from the PLC to a host device, such as a server, a database, or a display device, and automatically executes an action in response to the PFE message.
