In another life, I developed a large project in PCS7 V5.0. I created some custom function blocks and simulation logic that I would like to use. I am now working with Step 7 and Siemens PLCs. I tried opening the charts folder to view some CFCs in my old PCS7 project in Step 7. I get an error PCS7 hierarchy is not complete. I am using Step7 Pro V5.3 with CFC V6.0. I do not have access to the current version of PCS7. I seem to remember being successful by copying the PCS7 chart folder into a new Step7 project and recompiling. It does not work anymore. Thanks
