hi alireza ghasemi,

how do you read data?

Can you describe more in detail, what you are doing and what are you expecting what should happen?

regards,

Hi,

I would use SFC14 to read the Data consistently. This instruction also has an output parameter to get information about an possible error as return value.

Also check this FAQ:

How do you read consistent data from a DP standard slave/PROFINET IO device and write it consistently to a DP standard slave/PROFINET IO device?

Hi,

now I think I see your problem:

you copy PIW272 to DB1.DBW0 but the you copy PIW273 to DB1.DBW2 but next PIW would be PIW274 to DB1.DBW2...

PIW273 contains PIB273 and PIB 274...
