I have three DBs (Time, Parameter1 and Parameter2), each has 200 lines. Every time an event occurs in my system i write time and a couple parameters on one line. Nex event is later written on next line which is free etc. Now i can viw DB contents online, but i can see only one DB at a time.

I would like to have a table to see all three DBs at the same time. How to do that?

Something like:

Time  | Par1 | Par2

17:30 | 23     | 'xyz'

...       |     ...  | ...

Hello Ashadako,

Unfortunately, with the DB data or declaration view is limited to such customizations. However, there are a couple of closest possible alternatives I've mentioned below:

I understand you will be moving these values to a specific address or a memory bit. Have you tried using the Variable table? ( Under Menu PLC -> Monitor/Modify Variables in the LAD/STL/FBD application window). It is quite easy to monitor specific addresses across different data blocks in a single place with this. It is a pretty useful tool for modifying variables and in testing aspects too but I understood that might not be apt for your requirement.

The other possibility could be to view this data in the WinCC runtime. Adding the value of the DB is possible in an 'I/O Field' in the Graphic Designer (Under smart objects). I/O field supports different data formats like Decimal, String and Date/Time as well.  

Here's a link which could help you understand the I/O field configuration: https://support.industry.siemens.com/cs/ww/en/view/34602491

There are several other possibilities you could explore if you consider viewing this data in Wincc. Sharing the link of the WinCC manual here for further exploration. 

Hope this helps  

Thank you for the answer :)

Variable table idea sounds good.

How can I enter DB cell in this table? Help (F1) didn't help me.

If one DB is 200 lines long, do i need to create 200 VAT?
