The TwinCAT 2 Libraries are delivered with the Supplement Installation.
By default, these library files are installed in "C:\TwinCAT\Plc\Lib\". Depending on the library used in your PLC project, you need to copy the corresponding library file to "C:\TwinCAT\3.1\Components\Plc\Converter\Lib\" and then perform the following steps:
