Hello,

Hello,

I have a problem while sending a command to a lantronix device via tsend. I actually couldn't receive any data. I get status 7002 and busy = true.

Any suggestions please.

Hello,

if i could start with answers. Your situation isn't very clear because no clear info about success connection to server device and correct data send as some request. In this case I recommend for first to do some tests with PC application which can send and receive data over TCP/UDP (your info is also missing important type of protocol used). Typical good application is Hyperterminal over TCP/UDP or Hercules. From these applications you can connect to your device and check connection established and test also data exchange via expected protocol, message system. After this steps and with success of check all is ok, you can then better prepare PLC code. If you can and want next help, pls tell us more expected informations about your situation. ZIP some screenshots from code and of other block used and what kind of structure/memory you have set for send/receive of data. Also one important info is also missing - what PLC type, via what interface you want exchange data and also what SW you have available for programming. Without to know PLC type for sure, it's really not easy and correct to continue with support, waste of time.

Hello,

thank you for refresh of Topic solution. Yes, this is as I recommended previously, simply as:

Your situation isn't very clear because no clear info about success connection to server device and correct data send as some request.

In this case if you've attached format of send message example (from documentation) and your send byte sequence, it can be easy then find your problem quickly. Glad you have solved this.
