Hello, I tried to, but could not reproduce your problem. It works fine for me. Can you see mySchema.bfbs inside of your snap, when you unpack it? Could you share some of your code? That may be helpful to find a solution. Here is the registerType method in my try: auto bfbsPath = getenv("SNAP") != nullptr ? strcat(getenv("SNAP"), "/mySchema.bfbs") : "bfbs/mySchema.bfbs"; result = myProvider->registerType("types/mySchema/myValue", bfbsPath); Best regards, Nick

Hello, Yes there is a How to Use Graphical Programming in the developR series on YouTube. It's about a simple Pick and Place application. There our expert does a digital write to a PLC Variable in the Data Layer. Maybe this example can help you. Best regards, Nick

Hello Elleshar, I checked it with our R&D. This problem gets globally fixed for the ctrlX CORE with the release RM22.03 in end of march. Therefore you don't have to set your proposed linker setting manually then. Thank you again for reporting this issue. Best regards, Nick

Hello Elleshar, thank you for reporting this issue. We are clarifying some subjects and will answer you soon. Have you got some more information for us, on what you do in your cyclic event, which triggers the watchdog? Best regards, Nick

Hello Elleshar, Thanks for explaining once again. Your problem has now become clear to me. And I found a solution. You can store the .bfbs file in the Active Configuration of your ctrlX CORE. To copy the .bfbs file into the Active Configuration I used a interface hook. See this tread for further information. Add the folder "snap/hooks" and the executable "connect-plug-active-solution" to the project. Make it executable chmod +x connect-plug-active-solution 3 Changes in "snapcraft.yaml" a) Add part "flatbuffer" to get the .bfbs file into the snap (use organize to make the folder "/bfbs" in the snap) parts: ... flatbuffers: source: ./bfbs plugin: dump organize: '*': ./bfbs/ b) Add plug to the snap to get general access to the active configuration plugs: active-solution: interface: content content: solutions target: $SNAP_COMMON/solutions c) Add plug to the hook so active configuration can be manipulated in there hooks: connect-plug-active-solution: plugs: [active-solution] 4 Add command line code in the executable "connect-plug-active-solution" to create a folder and copy .bfbs file to the active configuration #!/bin/bash mkdir -p /var/snap/rexroth-solutions/common/solutions/activeConfiguration/bfbs/ cp $SNAP/bfbs/sampleSchema.bfbs /var/snap/rexroth-solutions/common/solutions/activeConfiguration/bfbs/ 5 You can change the bfbsPath in your C++ programm now to a path to the activeConfiguration: auto bfbsPath = "/var/snap/rexroth-solutions/common/solutions/activeConfiguration/bfbs/sampleSchema.bfbs"; result = myProvider->registerType("types/sampleSchema/inertialValue", bfbsPath); After installation you should see your bfbs file in the folder "bfbs" in the active configuration and your Schema is registered in the Data Layer at "types". Let me know if this solution can help you. Best regards, Nick
