Hi everyone. I've just found out a nasty issue with TIA Global Libraries and I need some help to understand if I'm missing out something. As you can see in the first image (global_library_1.jpg), each tag in the HMI tag table is connected to a PLC tag. The "PLC Name" column reports my current project PLC name. Having exported my PLC and HMI management into the Global Library, I tested it in another project from one of my colleagues, but I had this issue: when I imported the HMI tag table, every tag wasn't able to properly connect to its relative PLC tag (global_library_2.jpg). After some tests I've found out that, to make everything work properly, I must first change my PLC name to the one from the project from where the HMI tags table was taken and then I can change it back to the original one (global_library_3.jpg). Is this the normal behaviour? A bug? Am I missing out something? You can find all the images in the attachment or here. Attachmentglobal_libraries.zip (64 Downloads) |

When you store tags in a global library, unfortunately, the original PLC connection is stored with them unless you intentionally remove the connection before storing the tags to the library.

Oh, I get it. So even using Types in a Global Library won't solve the issue? |
