In a Zenon setup, I have two standalone gateways that are both connected to a firewall. The firewall ultimately determines which of these gateways will be used for fetching data from the process gateway. The data is being transmitted using the IEC 104 protocol. My goal is to find a way to monitor and determine which gateway is actively providing the data at any given time.

Additionally, I’d like to display this gateway status on the HMI for easy monitoring. Any insights into how to configure this in Zenon, or any best practices for tracking gateway selection, would be greatly appreciated.
