Post by timvh on Array to String CODESYS Forge talk (Post)
The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.

Post by benediktenger on Access project information of references library by script CODESYS Forge talk (Post)
Hi, I need to accesss to project information of a referenced library in the project. At least I need the "Released" flag from these information to check that no project gets shipped with unreleased libraries. Unfortunally, I do not get this information by script. I archieved to get the library reference object and the managed library object but both won't give me this flag but only basic information like company, name, version, etc. Here is my code: # get the library refernces proj = projects.primary objects = proj.get_children(recursive=True) for object in objects: if object.is_libman: for libref in iter(object): if libref.is_placeholder and isinstance(libref.effective_resolution,str): print(libref) print(libref.name) # get the managed libraries libs = librarymanager.get_all_libraries() for lib in libs: print(lib.displayname) print(lib.version) Does somebody know how do get these information?

Post by bruno-roth on Read "Homed" status from EtherCAT drive CODESYS Forge talk (Post)
Hello, the information if your axis is already homed you could only find out direct from your Slave. In DS402 status there is no Bit defined. But some manufacturer of Drives use some optional bits or status. E.g. if you have Schneider Electric LXM32 Servo you will find this information in Bit 15. You have to check the manual of your used Servo-Drive f this information is provided in any object and then read it out with SDO.
