Abstract

Systems and methods are provided for use in communicating with a distributed control system (DCS) associated with a manufacturing plant. One example system includes a virtual machine hosted in a computing device and coupled to the DCS via a network connection, where the virtual machine includes a controller server and a controller client. The controller server includes a controller specific to a process of the plant, and the controller client is configured to host communication between the controller server in the virtual machine and the DCS of the plant. The controller client, then, is further configured to receive a message from the DCS, via the network connection, transform the message into a JSON message, and communicate the JSON message to the controller server.

First claim

What is claimed is:

1. A computer-implemented method for controlling production of products at a manufacturing plant, the method comprising:
receiving, by a controller client included in a virtual machine hosted in a cloud platform, a message from a distributed control system (DCS) of a manufacturing plant associated with a process to produce a product, the manufacturing plant including a component for controlling a set-point of the process, wherein the message is in a first message format specific to the DCS;
transforming, by the controller client, the message received from the DCS from the first message format into a second message format different from the first message format;
communicating, by the controller client, the message in the second message format to a controller server included in the virtual machine;
receiving, by the controller client, a response message from the controller server in the second message format, wherein the response message includes an action to be implemented at the manufacturing plant, as determined by a controller specific to the process at the manufacturing plant, based on an operational state of the process;
transforming, by the controller client, the response message from the second message format to the first message format;
communicating, by the controller client, the response message including the action, in the first message format, to the DCS; and then
in response to the response message in the first message format, adjusting, by the DCS, the component of the manufacturing plant to alter the set-point of the process based on the action included in the response message.

2. The computer-implemented method of claim 1 , wherein the first message format is consistent with an open platform communication (OPC) protocol.

3. The computer-implemented method of claim 2 , wherein the second message format is consistent with a JavaScript Object Notation (JSON) protocol.

4. The computer-implemented method of claim 2 , wherein the virtual machine includes a first operating system; and
wherein the DCS includes a second operating system, different than the first operating system.

5. The computer-implemented method of claim 1 , wherein the set-point includes one of an evaporator pressure set-point and/or a steam pressure set-point; and
wherein the product includes glyphosate.
