I have a project developed in PCS7 version 5.0. When I open the project in S7 version 5.3 (CFC v6.0), I can read the function blocks and the hardware configuration. However when I open the CFC charts, I get an error "Could not read hierarchy folder, PCS7 installation imcomplete". Is this error due to the existance of SFC charts in PCS7 that cannot be read in S7/CFC? Do I need to first delete the SFCs in PCS7? I want to use custom function blocks in a non-PCS7 application but would like to make changes to some of the charts. Therefore I would like to view the chart that created the block in addition to the SCL/IL code. Thanks.
