Optimized communication between edge applications and control application

A method of controlling communication within an industrial system, the method comprising:

• executing, with an industrial controller of the industrial system, a control application to control performance of an industrial process of the industrial system, wherein the control application is locally stored at the industrial controller;
• retrieving, with the industrial controller, tag data related to performance of the industrial process, wherein the tag data is specific to a tag related to performance of the industrial process;
• routing, with the industrial controller, an electronic message including a portion of the tag data to an edge application subscribed to the tag, wherein the edge application is locally stored at the industrial controller;
• and
• executing, with the industrial controller, the edge application based on the portion of the tag data such that the edge application performs an edge function related to the industrial system using the portion of the tag data.

A system for controlling communication within an industrial system, comprising:

• a programmable logic controller (PLC) of the industrial system, the PLC configured to:
• execute a control application to control performance of an industrial process of the industrial system, wherein the control application is locally stored at the PLC;
• retrieve tag data related to performance of the industrial process, wherein the tag data is specific to a tag related to performance of the industrial process;
• route an electronic message including a portion of the tag data to an edge application subscribed to the tag, wherein the edge application is locally stored at the PLC;
• and
• execute the edge application based on the portion of the tag data such that the edge application performs an edge function related to the industrial system using the portion of the tag data.
