Custom Libraries - Cascaded / Sub-libraries

Hello Community!

I am in the process of creating a custom library and wondering if there a way we can create “sub-libraries” within a released library. For example, PLCnext’s CANbus library and its sub libraries as seen in the image below:

I did find something regarding cascaded libraries (https://engineer.plcnext.help/latest/\_index.htm?iframe=https://engineer.plcnext.help/latest/LibraryManagement_ReleaseLibrary.htm) but I am not sure how to approach that if that is the solution.

Any guidance would be greatly appreciated!

Thank you!

Hi chret27,

you can create cascaded libraries by releasing a project as a library which contain references to other libraries.

Taking the screenshot as an example:

You start with a project, reference the PLCnext Controller lib and release the project as AsynCom_9.pcwlx

After that you start with a project, reference your freshly released AsynCom_9.pcwlx and release this project as CANbus_11.pcwlx

Now you’ve created the structure in your example.
