Repetitive upload in 800xA PLC Connect

Hallo,

if I perform PLC upload in 800xA 5.1, all the objects in OPC server are retrieved, corresponding objects in Control Structure (CS) are created and I can see live data from the PLC. However, if I make the same upload once more, all the objects previously created in Control Strcture get their Variable Connection broken (radio button in Signal Configuration aspect is set to Not Connected). Furthermore, the values in PCA aspect have good quality, though the connection is broken.

Is it possible to make the PLC Uploader work the same way as MB300 Uploader does? It means:

1. Objects existing in OPC server and not existing in CS are created in CS

2. Objects not existing in OPC server and existing in CS are removed from CS

3. Objects existing both in OPC server and in CS are left untouched, including Variable Connection and other settings in Signal Configuration aspect

Thank you for answer
