Process control communication architecture
First Claim
1. A platform-to-platform method of communication between industrial computing devices in a process control system comprising:
- enrolling a requesting industrial computing device platform in a process control messaging service in response to a request for enrollment from the requesting industrial computing device platform, the requesting industrial computing device platform and the process control messaging service each having a framework of a communication protocol of a destination industrial computing device platform layered above a communication protocol of the process control messaging service, and the protocol of the process control messaging service layered above a network communications protocol;
receiving a wrapped message from the requesting industrial computing device platform via a communication transport type associated with the networking communications protocol, wherein the message is generated by the requesting industrial computing device platform in the communication protocol of the destination industrial computing device platform and wrapped in the communication protocol of the process control messaging service having a header comprising the identification of a destination industrial computing device platform and the communication protocol of the destination industrial computing device platform;
decoding the wrapped message into the communication protocol of the destination industrial computing device platform; and
forwarding the decoded wrapped message to the destination industrial computing device platform.

Abstract
A platform-to-platform communication architecture for a process control messaging service in a process control system or other industrial setting allows stationary and portable industrial computing units to communicate with each other, in one-to-one and one-to-many communications, and across networks, including isolated networks inside the process control system or industrial setting and external networks. A requesting industrial computing device platform generates a message for a destination, or responding, industrial computing device in the communication protocol of the destination platform, and wraps the message in a communication protocol of the process control messaging service. The communication architecture decodes the wrapped message into the communication protocol of the destination industrial computing device and forwards the decoded wrapped message to the destination. The communication architecture allows for a variety of communication services, including, but not limited to, instant/real-time peer-to-peer messaging, time synchronization, automatic data transfer with an asset management system, communication with field devices via an asset management system and large data transfers.
