The thing seems to be that the OPC browsing function within the DB folder would require special information provided by STEP 7 Basic but this is not open accessible for SIMATIC NET yet... therefore you need to go another way. What you need to do is specifying your data manually. So for example for the DB 1 DBB 0 you would use: S7[S7-Connection_1]DB1,B0 in if you want to use areas you will need a repetition factor at the end. That's it. Try it yourself. Best regards J_Bell
