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.

Which RaspberryPi OS - have you installed on the PI? At the moment, there is a problem with latest Bookworm from December. You need to downgrade to October version of the OS - or wait 4.11.0.0. is released ( February) https://downloads.raspberrypi.com/raspios_armhf/images/ 2023-10-10 16:13 Version will work.

Could not find the solution to this issue but I have side stepped this by creating a global variable MAX_SIZE.

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.

Have you cross referenced the variable to see if it is being written some where else? You could try an Execute block instead of a Move.

I put the cross reference at the bottom of the pictures. It is not being written to elsewhere. I have tried the execute block too.
