C#_clientAppl and EthServer

hi everybody,

I want to communicate with a dx200 configurated with ethernet server and a c# .net4.8 appl.

I make this test

- client Hercules<>dx200 : ok, the data transfer is correct

-client c# <>serverc#(or server hercules) :ok

-client c#<>dx200 : problem

The socket seems open good, but when i send command i receive null answer from robot.

Also the first command doesnt work

"CONNECT Robot_acces Keep-Alive <CR><LF>"

What can i do??

hi everybody, luckly i solve by my self the topic.

For everybody who wants to use the c# TcpClient class with yaskawa ethernet server i suggest.

....

Command="CONNECT Robot_acces Keep-Alive <CR>\r<LF>\n"

New stream =Tcp.Client.getStream()

Byte[] Byte_data= ... convert the string

command in byte char

Stream.write(byte_data,0,byte_data.length)

....

The <CR>\r<LF>\n was the big enigma to find for the correct exchange😑

Thanks, good luck!
