Incorporation of C-Functions as CoDeSys Library 139WAGO I/O-SYSTEM 750I/O-IPC-C10E, CANopen Master[EXT_LIB_LIST]1=mytest[mytest]1=MyTestFunction[EXT_LIB_LIST]1=mytest2=CSV-File[mytest]1=MyTestFunction[CSV-File]1=ReadCSVString2=WriteCSVString13.1.2 Creating a Description File for the CoDeSys RuntimeSystemCreate a description file with the fixed name "extlibs.ini" in order to make the C-functions known to the CoDeSys runtime system.1. So that the runtime system can recognize the Linux library and correctlylink to it during startup, you must create an INI file that contains all librarynames to be loaded dynamically and their function names. The INI file forthe example appears as follows:Figure 94: "extlibs.ini" file2. If you would like to add additional libraries under the entryEXT_LIB_LIST, add a continuous index under the corresponding librarytag, followed by library names (e.g. "2 = CSV File"). It is not necessary toprovide the transfer and return parameters of the functions at this point.The correspondingly expanded file would appear as follows:Figure 95: "extlibs.ini" file
