Summary: | The subject invention provides reliable messaging with and within a control environment. The systems and methods utilize a message broker (350) that facilitates message exchange. The message broker can be located within an industrial controller (340), as a dedicated entity within a control environment (310) and/or an entity external to the control environment. Messages transmitted from an industrial controller and/or the external entity can be routed through the message broker prior to reaching a destination, wherein the message can be stored in the message broker and subsequently obtained by a recipient. The message broker decouples the message sender ( e.g ., an industrial controller, an external entity...) from the message recipient ( e.g. , an industrial controller, an external entity...) such that messages can be successfully transmitted (to the message broker) regardless of a state of the recipient, and messages can be retrieved (from the message broker) regardless of a state of the sender. |
