This error message tells you that you create virtual connection name at connector CRT of function block CTV (20.CRT), but this virtual connection does not used in the program. After creating a virtual connection name at CTV/CRV block you should create at least 1 virtual connection at any other function block (at input connector for CRV, and at output connector for CTV). For this right-click at any in/out connector of some function block, then select 'Interconnection to Address', then select 'Virtual connection', then select in drop-down list the name of your virtual connection and type a sequence number. Look at attachment. You may read about how to operate with virtual connections in the manual of Simadyn D. Go to the Start-Simatic-Documentation-English and find the manual 'D7-SYS - SIMADYN D System and communication configuring', find the chapter 'Communications utility process data'.
