Could someone please share reference documentation for interacting with a device's IP settings from a visualization/webvisu? Is what is outlined here still valid? https://forge.codesys.com/forge/talk/Engineering/thread/ad11c199a2/

There still is no solution to this. I am running Modbus version 4.4.0.0 and it still wont let me add more than 10 channels. Does anyone have a solution for this?

Do not filter on Phoenix devices. First add an Ethernet device (from CODESYS). Then add a Profinet Controller (from CODESYS). Then add your Phoenix devices to this CODESYS Profinet Controller.

Hi there, I am having a similar problem like you. I have 3 screens connected to one PLC. I have set 3 different URLs for them. But 3 of them are still dependent to each other. How can I make them independently ? Kind regards, Jin.

I think it is a similar issue, but different. I saw you use AWS IoT Core. AWS limits you in this - search in page here for text "Subscriptions per connection" it is 50, cannot be changed.
