plc - Twincat Serial communication function - Stack Overflow.Example 2 - Application of virtual Com ports
Twenty years from now, I want to be able to compile and build the exact same executable binary that is running on that nice expensive machine right now. I have two developer machines, one running Despite making sure that I always selected the correct version of the target in the TwinCAT remote manager , and even making sure I had the exact same source code on my two different developer machines, I always got this screen when logging in to the PLC after making a build:.
So, even despite I made sure I had the exact same software on both computers running the same TAG from version control in GIT and despite selecting I also made sure to follow Beckhoffs recommendations for source control , so that should not have an impact either.

Select the correct version for all the libraries. This is how the library references now look like after selection of the latest library version for TwinCAT Now, when building and compiling your TwinCAT software on different developer machines, you can always be safe and know that all dependencies are fixed and that the compiled binary will always look the same as long as you have the version of the TwinCAT XAE installed which corresponds to the version of the target runtime XAR.
