Mark with the cursor the block folder and open "Edit > Check Block Consistency...". In the following dialog use the function "Program > Compile All. After then, if you have 0 Error, load the CFC/STEP 7 program in the CPU again. Otherwise, check the installation version of your CFC and if possible make an update. For CFC V7.1 there is the SP2 in the internet. Please see the link: http://support.automation.siemens.com/WW/view/de/44900589 With best regards Cicero
