Send the packet

[parksh]

Hi?

I like to send a some packet to modbus/tcp device to control it.

I do success in python as follow:

==============================

sdata = struct.pack('BB',0x00,0x00)

sock.send(sdata)

=============================

and it works well;

but now i don't know how to do like this in Autoit.

if anyone knows, Please let me kown.

i try to do like this:

$szData = Binary("0x00,0x00")

TCPSend($ConnectedSocket, $szData)

but this does not work like above python source.

Liek this:

TCPSend($ConnectedSocket, $szData)

this is my want to send data

$szData = Binary("0x00,0x00,0x00,0x00,0x00,0x09,0x01,0x10,0x00,0x08,0x00,0x01,0x02,0x00,0x01");

but i can't send it.

why should Binary("0x00,0x00") be change like Binary("0xBB0000")?

Because AutoIt is not Python. You're using the AutoIt function, not the Python function.

Hi,

I'd like to creat some scripts to automate a module using Modbus TCP/IP.

So I'm looking for the libary for this fucntion. I knew you worked on this long time ago.

Could you share me your script please? Send to me at kduanvo@yahoo.com

Thanks
