S71200 TCP/IP communication with scanner card

Dear Experts,

Warm Greetings !

By using TCON,TSEND,TRCV,TDISCON block,I am trying to make communication with my scanner card.By using scanner card's IP,I connected to it successfully. But problem is,I could n't able to send and receive commands.

Multi line strings are not possible,for each and every single line command i should get response from my card,so that I can send next command.

For some commands,I am getting some response,for next one I am not getting expected one.More over Response are so lengthy and repeated letters are coming.



I guess the commands i am sending are accumulating in buffers,Give me a suggestions to clear it.

Hello Everyone,



Just an update:



Issues with communication got solved in my program.Instead of sending string as input data,we tried with characters as input data.Its working fine now.



Thanks!
