Abstract: A method and related system of message prioritization in a control system. At least some of the illustrative embodiments are methods comprising receiving a first packet-based message from a first software package across a high bandwidth channel (the first packet-based message directed to a first software port), receiving a second packet-based message from a second software package across the high bandwidth channel (the second packet-based message directed to a second software port), selecting the first packet-based message based on the first packet-based message being directed to the first software port, forwarding the first packet-based message across a low bandwidth channel (the bandwidth channel of the high bandwidth channel higher than the bandwidth of the low bandwidth channel), and then forwarding the second packet-based message across the low bandwidth channel.

Abstract: A method and related system of a method and system of field device protocol masking. At least some of the illustrative embodiments are methods comprising receiving a message in a first protocol format from a field device of a control system, modifying the message to create a modified message (the modified message in a second protocol format), and forwarding the modified message to an upstream device that communicates using the second protocol.
