Error Compiling 'OS' PCS 7 OS (Server/Single Station)

Hello!

I created project with help "Integration of S7-1500 Package Units with SIMATIC PCS 7/OPEN OS SIMATIC".(Pic. 1)
[snip]

I assigned graphic symbol name with object 
[snip]

I try "Start compilation", but an error occurred:  Error Compiling 'OS' PCS 7 OS (Server/Single Station)

[snip]

Plase, help. What does this error mean?
Also there may be somewhere there is a more detailed description of the error?
In site pictures were cropped.
Pleas, open full picture.
Thank you!

Hi Olgas,

I think, You have missed the assigning of hierarchy folder of an OS in DBA.

Please assign the OS and recompile the station once again.

Please go through the section 5 (5-Configuring the PC station with the DBA) from the bow doc link

Integration of S7- 1500 Package Units with SIMATIC PCS 7/OPEN OS

Hope it helps you!
