Hi,
I have successfully able to transmit hex commands over serial port to my device and receive the replies in hex from it. I was able to confirm this by changing the display format to hex for the control and indicator. Now I want to store portion of the received hex data and use it in my next commands. Example of received data as below:
F00D 0010 1100 0001 E002 2C4D 6C93 4D7E AA66
The blocks in red will be incorporated in next command so that when I sent this command it will look like this:
F00D 0014 2000 0003 E002 2C4D 6C93 4D7E 0000 0020 77AF
In summary, send command and get reply, extract and store data blocks in red, then send different command containing the data that is stored. Everything is in hex format. Question is how can I extract/store the wanted bytes and later reconstruct a hex command containing those bytes? Should I convert to normal string, byte array, or hex array? If the last 2 conversion methods are used, I need to ensure that the zeros are not lost.
I have attached my VI. Please have a look and help to provide solution.
Thanks in advance.
