Dear Forum Users,
I have a problem with TCP communication betwen S7-1200 and SICK Inspector camera.

UDP Communication works great i have clear values in DB block, but with TCP communication, data string in data DB block is putted randomly.
Please find attached print screens for more details. What I'm doind wrong?
Good value in Data 2 should be Rotation:22.99.

With UDP communication all works great. But i don't have protocol builded confirmation.

I can only add 1 attachment, so please find onedrive catalog with more details.

Thank you in advance.

Hello,

you need to set in case of different receive length messages (look to TIA documentation in which cases you need to do this) ADHOC to true. In some cases (it depends to CPU version/firmware) you need set only LEN=0 but with CPU firmw. 4.1 f.ex. you need set also ADHOC true. Without this, you can't have reliable results. Also if you will expect same LEN of receive message everytime, I recommend use ADHOC with true for sure.

Update: you've ask for TIA v14, I don't have still it so therefore I recommend see TIA help about needed instructions. My info is standard.

Hello,
I kindly thank you for your responses.
Now its work fine, but also in UDP i have a problem with cutting first 2 chars in string.
But it's not a problem for me in futher applications. 

So i set LEN := 0 and ADHOC := True and looks fine (please find attachement).

Previously i setting LEN := 0 and my string filling up with lot of values "Rotation:xxxxRotation:xxx" and so on. So my mistake was ADHOC := False ;)

PS for next persons who looks at this topic:
You can download function block generator from SICK website and you can generate FB block for values that you need.
