An industrial controller that can be utilized in an environment that
supports message queuing comprises a receiver component that receives a
message from a queue, wherein the message conforms to a message queuing
protocol. A message queuing component communicatively coupled to the
receiver component interprets the message and alters control logics
within the controller based at least in part upon contents of the
message. Furthermore, for example, the message queuing engine can be
configured to generated messages that conform to the message queuing
protocol.
