Hello Sie-auto

Yes Kahl is right! there are only Booleans in the DB. If you want to get a decimal "sight" on the Tags then you have to define the HMI Tags manually with absolute Adressing.

But be careful, you do not have compiled your DB yet because of the ??? -> There mus be the Offsets that you can use it.

Bye Murof

Thank Burof and and Kal.A for the answering but I think you were not right. At the DB already had F2START_TIME tag is interger. 

Now I attemp to solve out the problem and seen that the problem as attached file here but I don't know why? if the UDT or the Structure that I insert into the DB has tick (see the capture) then I can pick the tag into WinCC Pro but with the old UDT, I can not. I will look more time to understand what happend with the UDT I already created 

Thanks

Because they're not checked in the PLC Data Type. Check them there then update the tag in your  DB.

 Yes, I found that no check but for some reason, I do not know why the UDT or Structure does not allow to check but when I create another one, it can be check. 

 Hi Sie-auto,

I met the same problem as you did. I have struggled for a while and could not find why. Thank you for your question and the posting diagrams, now I solve the problem!

But still not sure why some UDTs are not allowed to check.

Best regards
