Hello,

I have some trouble to send data as IO controller to a IO device over profinet using the CP343-1.

I managed to do the receiving part without problems.

The FC11 PNIO_SEND give me nothing on ERROR no anormal STATUS word and DONE is switching to 1 regularly as well as CHECK_IOCS.

And it seems i'm not receiving the expected data on the device which should be in the adress range from 344 to 463.

I don't understand so well te IOCS principle but i suppose that the problem should be linked to the fact that I have the CHECK_IOCS to 1.

You'll find a copy of my FC11 block, Send DB and HW config with profinet network adressing.

Thanks in advance

hi LATOR,

how did you check the Error/Status?

the Information on Status is only valid for one cycle. you need to save the value when Error = true.

There´s a FAQ with application sample available:

How do you program communication blocks FC11 and FC12 for the PROFINET IO device?

hope this helps,

regards,

I move the status to a temporary memo when ERROR = 1.

But as I said this never happen.

Otherwhise the status value is either 0000 or 8180 which is normal.

hi LATOR,

do you get the DONE-bit?

regards,

Yes except the check_IOCS which goes to 1 everything seems fine.
