CPU 313C Integrated I/O porblem

Hi

Iam using CPU313C model 313-5BE00-0AB0 firmware V1.0. I have downloaded the program. There are some digital inputs active in the integrated DI module. But the same is not appearing in the Step7. If I see in the VAT table it is showing as Inactive. Software couldnt able to read the integrated IO status.

There are some additional IO cards available next to integrated IO cards. The IO status (DI) of additional cards are reflecting in Step7. Is there any problem in the HW connection?

Does anyone have an idea about this issue?

Thanks

I guess that the integrated I/O has power.

Check in the HW-configuration what adresses they have. With MMC-cards you can change the adresses of the I/O.
