Shared Declaration folder in a Step7 project

[PLC]

When does a shared declaration folder show up in a Step7 project?
I will sometimes see this and there are units in the right hand pane

Hello PLC;
I have seen this Shared Declarations folder only in PCS 7 projects.
Have a look at the following Siemens FAQ, see if it corresponds to what you are looking for:

Hope this helps,
