Hi,

Maybe you would like to explain the changes you made to make it work. It would be tremendously helpful for others who might face the same problem.

Hi

I used the sample VIs " S7Com_2009_11_06.zip"(you posted the link) and changed the lenght then it works.

Hi Sir, 

For siemens smart PLC, the same method, right ?

Could you share your PLC side setting(the pic is not able to see) and the "S7Com_2009_11_06.zip" ? 

Thanks very much.

Already find it from that previous link, thanks.
