Hi all, just for a little more assistance, I've found that in the folder C:\Users[user]\AppData\Local\T\A on my machine, there is a file library_index.json. In that file is a complete list of the available libraries and versions that you can use in the PLC IDE sketch library designation. It seems that the PLC IDE uses those links to then download the library you choose. For a given library, i just choose the latest version available in that file and it'll grab it without any worries. This isn't always the latest available in the Arduino IDE. Interested to hear if this works for others too.
