Modifying Identification and Maintenance info with TIA portal

Hello Siemens experts.
Trying to figure out how to change the I&M data of a Profinet device with TIA Portal, and I can appreciate advice from the experts as so many times in the past. I have tried to change the I&M data in the TIA portal project, then building the program with no errors. But, when trying to download the modified program, which must be different because the I&M data has changed, the TIA portal says:

"The configuration will not be loaded, because the online status is up-to-date. The configuration will not be loaded to module <<PLC NAME>>, because the online status is up-to-date."
As a result the I&M data in the device does not change.

It seems the TIA does not regard the change to the I&M data as a change to the PLC program. If I try using the online diagnosis for this Profinet device, I can see the actual I&M info but cannot change it. Is it possible that TIA portal does not allow the modification of I&M data, or more likely, my TIA Portal skills are insufficient?

By the way I am able to change the I&M data using PRONETA software and the licensed version of Profinet Commander, but I need to know if it is possible to change the I&M with TIA Portal.

Thanks very much for your words of advice.

Maybe obvious but you are downloading the hardware confige and not only the software ?

Hi, yes I tried downloding the hardware, but result was the same.

I don:t have specific knowledge nor experience using I&M data but a quick search indicates that the data is exchanged using RDREC and WRREC instructions.

Hello kalabdel. I&M0, I&M1, IMM2 and I&M3 are indexes 0xAFF0, 0xAFF1, 0xAFF2 and 0xAFF3, respectively. So yes, it is possible to write a program with RDREC and WRREC instructions to change these values. But what I need to confirm is whether TIA Portal has the functionality to accomplish this without writing a program, like for instance PRONETA does. I was not able to figure out how to do this, so it may not be possible, reason why I am trying to get such confirmation from some forum member with deeper TIA portal expertise.

Execuse my ignorance, have you looked at this page 73?
And this is V16.

Thanks very much for this manual. it seems to be supported. Need to look into this a bit further. Will try this later.

kaladbel, thanks very much for reminding me the golden rule of "read the manual"

That's a good rule, but which manual? The got like a couple of hundred of them.


Glad you got it figured out.


Cheers

The one you pointed out in your post # 6 above and which I showed in post #7.
