Hi @ernie.sparks,
There may be a missing library in your project. Could you navigate to your library manager and see if any are missing? Below are some instructions if needed.
- Double click to open the “Library Manager”:
- Within the following menu, select “Download missing libraries”:
- Follow the prompts to download any missing libraries:
Note: A library developed by Weintek cannot be retrieved using this method. Instead, please install our Codesys package on this PC. We highly recommend using Codesys version 3.5.15.50.*
