I have some function blocks in an application that I'd like to put into a library(compiled or not). These function blocks use some external variables and functions from the application. After creating the library and adding to the original application and compiling, the compiler complains about the external variables/functions of being undefined, not even standard function blocks like TON. Is this behavior normal? Because as I recall this was not a problem in Codesys V2.3. How can I resolve this?...
