Hi @andreal, Were you able to adapt a codesys runtime to your linux based device? I am planning on the same lines. we want to develop a small controller of 64IOs for our application. We want to adapt codesys runtime on our Arm processor based embedded linux boards.

There appears to be a limit to the number of OPC Servers that can be connected simultaenously. 1-10 work but adding an 11th makes one of the previously linked ones unavailable. Is this a soft setting that can be adjusted? Using 3.5.18.30 on Win x64

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.
