Dear all

I uploaded a program from S7-300 system and found in the logic, I90.2 and I90.6 existed. But in the Hardware configuration, the maximum address is 27 (I27.7 is the last)

anyone can explain ?

thanks and regards

Hello,

have take a look in the adress overwiew in HWConfig if the Adress 90 is listed here?

Hi

No, It's only 27. Pls see the attached picture

 Dear Friend,

Address i90.2 and i90.6 may be not defined in hardware configuration but used in software.

 Thats only the central placed modules!

In HWConfig go to view -> adress overview

here you get the list of all addresses from the project!

For example, if the adress 90 is configured in the DP interface you see it in the list, an not on the modules!

Oter reason can be that address 90 is assigned to a slave which is configured with a GSD File and you haven't installed this GSD so the device is not displayed.

Thanks 

So, it is just used as an intermediate memory (like M memory) ?

I wonder because it is not generated by any logic (it come with AN,A, O logic only)

How to understand this ?

The address overview do not show, the I90 in GAP address (see the picture)

All modules can be see in the catalog. Any other GSD I missed ?

Thanks 

Hello kietnt81,

Perhaps you can give some information about project?

Are you using Slave's, HMI's. Is there some connection with other CPU's etc.

Best regards,

Wizard

Please see the attached project

Only CPU, IO, IM360, IM361

No HMI, 1 CPU only
