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.

Hello everybody, In an upcoming project we are supposed to control a display board via NTCIP. Unfortunately, I have not yet found out whether this is possible with CODESYS. Are there any libraries for this in CODESYS? Best regards

Hi eschwellinger, Thanks for replying, but I'm not shure if I got it right. Do you mean that I have bad configuration on my CODESYS config file? Or in my project? Thanks in advance!

Hello, what CAA stands for? Since it is a collection of different libraries, does it mean it is created by some specific organization? Thanks!

No that is not possible for function blocks, although it is possible to that with methods and functions as you see in your second pic.

What do you think about having an AI Agent specialized in ST programming in Codesys? I see this saving hours and hours of work for those who program on a daily basis.

Dear Forum, For anyone interested we have solved this problem. Before we were using a KNX TP/IP interface, now we are using a KNX TP/IP router, and it works like a charm now.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
