Hello,

really hard to give Smart support here. If i can ask you kindly, share screenshots (ZIP them in case of more) to see your blocks parameters what you have set to them and also what is more important, to see your buffer for recv data. In case of receive, here can be problem because within receive there isn't clear info how much data are received. In this case we need to see description of recv block to see what parameters are there and how to best set cfg to have best results.

maybe I expect this, in case your buffer is long 10 bytes and you send from PC 10 bytes, then you can have all inside after send/receive. Sometimes is expected to fill full buffer's elements prior have some output from block about success receive. here check of more parameters like error or status with combinations (documentation) is required inside your code to detect functionality state.

Hello,

as I said in first post, due not full support to Smart HW/SW here on Forum is hard to help. Your prj I can't open due not have SW. From screenshot isn't very clear what is happen inside CPU. Connection settings, parameters, IP and Port values of PLC and PC with Hyperterminal SW are also missing. I recommend use better Hercules SW (find on web) than Hyperterminal because of maybe problems with Country Page defined char tables. Again, I'm not sure if someone can help you here with Smart but if you attach more expected screenshots inside ZIP, maybe we can go further. Pls be kind understand that Connection status is required to see for sure.
