What is the fastest and efficient way to do a cross reference search?

For instance while programming I want to check usage of %I2.5 or DB10.DBX5.2

I am still too used to using Step7 5.5 and the goto function. 
Even in step 5 you can do a search for a particular address and pull up the info 2-3 seconds starting from the moment you press F2. e.g F2 twice then type address and bingo. 

I find it a little slow and cumbersome to pull up the cross references for the specific DB or IO table. 
e.g click on the DB then press F8 then navigate to the address location and then open up 2 levels to find specific use. if the DB is heavily populated then there is additional processing time each time to generate the table.

There is a nice feature in TIA portal and that is the Cross reference tab under the Info tab which quickly brings up cross references of the addressed logical elements you have selected on the page. this is fast enough for me. Except that you need reference there on the current page to access it. 

If only there was a field to enter the address there and display that cross refference instead of the selected item. 

I am new to TIA portal and am slowly trying to become more efficient in using it as it is the Future of Siemens automation. There is much i dont know about using this software. 

I would like to know how others are programming with it.

Thanks for the list Solutionfinder

A handy list to have certainly. 

But what is your process of checking cross references quickly in TIA portal?

What version of the portal are you using?  V10.5 cross referencing is a little different in V11.

There is a menu option in V11 to do cross references.

For a DB, you can often right-click on the DB from the project tree to get a cross reference.  You can do similar for a plc tag table.

Helpful? Rate it.

I am using V11 SP2 Upd2 (Thanks J_Bell)
And am currently reviewing code in my first 1200.

I have been using the tree. (instead of right click i left click and press F8)
I also use the Info tab -> Cross reference tab

But access to desired cross referecnes of adresses not on the current page is not as fast as I like to work. 

Also I have noticed that when using the tree to get the cross reference for DBs I dont get any cross references for structure elements. 

Am I missing something?

I am happy with the speed of the info tab cross references. Although if I have it open all the time it can slow down other program operations slightly.

For DB xref, the > to the left of the DB means you can expand it.  Click that, then you see all the xref for the structure within the DB.  Look at the individual items in the DB and some or all will have >'s.  Expand them all with a window icon (hover over the options to find the one that does it).

The portal getting started section of the help system describes more about the interface and the icons and the cross reference options.

Hi,

In TIA you have possibility as in Step-7 to right click on the variable and choose goto -> read/write access. Only problem is that it does not work as it should. I have opened support case for that and Siemens developement team is working on the issue I think already for several months. I hope at least hot fix will be released soon and we will be able to use goto as it was in Step-7.
By the way, cross reference tab at the bottom was also available in Step-7. Sometimes its very handy, but it can't replace goto which is fast and very optimal way to reach your variables.

Regards,

I worked only on one project using the portal so I have not developed all the tricks yet to be efficient. It does not help that all the shortcuts with the F keys have changed (NC contact, NO contact, box, new network, new branch etc, and Ctrl-Tab does not work)

I too would like to know how to get similar operation to the Go to -> Location found in Step7. I use this functionality all the time, litteraly, to find my way through a program.

I hit Ctrl-Alt-Q on any item, the Go To form pops and I put in the any address I need to look out. Often this address comes from an opened VAT I am using for diagnostics of the specific issue I am looking at. In 1 or 2 seconds I have all the information needed. I agree in the Portal it is cumbersome in comparison to go to the specific DB, navigate inside it to find the reference (sometimes buried deep in structures or large DB) and do this multiple times.

I guess the use of the Go To feature is a matter of preference of how to use Step7, but I feel it is a very efficient way of finding what you need, The fact you can also sort by access type by simply clicking the header, and get the writes or reads first is also nice.

I would be interested to hear further comments from other people using Go To extensively, typing addresses directly. What is the best alternative/workaround you ended up using to get a similar result?

Thanks,

Frederik

Ironically I found that the WinCC tag tables were more useful for cross referencing back to the S7 program than using the individual DB cross reference list or the DB itself (which cant be used).

i.e. using the Info/cross reference tab i click on the Wincc tag in a floating table and i get all uses of the tag in step 7 and Wincc.

perhaps its a bug in my system. sad

Is this the same for everyone else or is what Huggy_d1 says is true, that im supposed to see a drill down menu in the cross reference list? 

I dont get cross references for structures in the DB cross reference list or from the DB table. 

See attached image of a S7-1200 program using SP2 Upd2.
