MEMORY ADDRESS OF DDT VARAIBLE CHANGES AUTOMATICALLY IN M580 CONTROL EXPERT.

[kishore1march]

Dear,

I created a DDT and given a starting memory address, so the variables that are inside the DDT are auto assigned as per given starting address. 

Now i have  noticed many times the memory address inside the DDT changes automatically after download with any man intervention.

Can u help how to stop the autochanges of memory address.

Kindly see the attaches picture with redmarkup.

Hello @kishore1march 

You can change the setting of DTM to be the same as the attached print screens and use the DDT structure to get the data and the status of the communication "Freshness"

The %MW address changes? or the internal adress %UW? How many instances of the DDT do you have? Can you attach a picture of the structure?

Dears, 

Thanks for your time.

Issue was resolved.

My mistake was - real address were started with odd numbers(%mw7) which lead to wrong display of values. 

I corrected the address to even numbers(%mw6) which fixed this problem.
