Hi

We have a control system consist of :CPU 315-2DP and MP370 

Already, we have the final Backup program of the system.

We added  some modifications in the final PLC Backup program then downloaded it to CPU

After that we face a  problem in the display values in the HMI 

My friend told me the problem due to the Data Block

and advice me to download the old Data Block values plus to the modifications

Is this right?

How can we execute it?

Good Bye

 Iam using Simatic Manager

Nzett11

do you use TIA Portal for that?
As far as I know, the MP370 is an old product and is not supported by TIA.

Hi Pepsi Cola,

Pay attention at the size of old DB_Block.  The new block must to have the same size.

I suggest you to take the old DB_Block, modify or add elements at the end fo DB_Block.  Don't erase, neither modify, any spare information, because maybe the HMI reads this ítems.

Hi 

Our experts tell me to take the online data block and modify or erase on it according the required modifications.
