Vasya Posts: 19 Rating: (1)	Hello. There are problem in Step7 v5.5 when I try to view some networks in LAD or FBD view mode. But in Step7 v5.4 same networks in LAD or FBD view modes are looked OK. In the attached screenshots listing the command "BLD 102" points to origin of creation language. Is there BUG in editor or something else? Thank you. Attachment Step5.5_question.gif (363 Downloads)

To fix it, open any block, go to the Options menu, select Customize and untick "Type check of addresses" in the LAD/FBD tab. I hope this helps

Testermax Posts: 159 Rating: (3)	Hello! Whats is the drawback of unchecking the "Type check of addresses" in the LAD\FBD editor? I have the same problem, a quite big network, which will only appear in stl (when "Type check.." is enabled). To me it is very comfortable to just uncheck this "Type check..", but will the compiler still notify me as usual if I make some programming error, or Im I in any risk diabeling this funcyion?

I suggest that you leave it on and only if you are sure your logic is righ or want to read the code in FBD to turn it off. Regards, Marcjan

Now im unabe to enable it again?.. /Kasper Hallo, I'm in the same situation....I found out that this option become gray after the installation of Hotfix 8 OR Hotfix 11. As you can see in attachment, the option "type check of addresses" (in italian "Controllo tipo di operandi") in STEP7 5.5 with SP4 can be enabled/disabled. I keep it enabled and after Hotfix 11 installation it became disabled and unchangeable. The same with hotfix8. (i'm working in Win7 64) Some Solutions?
