Abstract
A message management facility is described herein that is hosted by a networked node, in a process control network environment, that is separate from a control processor. The message management facility routes a stream of messages received from the control processor to a set of destinations on a supervisory network. By interposing the message management facility on a node that is interposed, in a message steam, between alarm message sources (control processors) and alarm message sinks (workstations, printers, historians), a number of additional functions can be implemented to carry out a number of advanced functions. Examples of such functions include: table-based routing of a single alarm to a number of destinations on an application network, suppressing alarm showers by applying a criterion to received messages when shower conditions have been sensed, invoking commands based upon a configured category assigned to particular identified messages prior to delivery of the message to its final destination, and invoking actions in response to event/mode status changes (including re-prioritizing alarms).
