Can Someone Explain This Code Please...

[Stuart_Wales]

See photo, I've used the help feature but it's not helping much..... Especially the ">SFLD 3" command?

Code is linked to a 12 character ASCII input from HMI (which I am extending length to 16 characters), and then sent to a laser controller to mark a part.

The C24 module is set to byte processing instead of word.

As for the >SFLD 3 [D9500.D9501............] [H0D] command you will have to consult your laser controller protocol

Hi Gambit, what do you mean by C24 module?

QJ71C24(r2 or R4). This is serial communication right?

Ending the string with CR (hex 0D)

The $MOV moves that specific character string ">SFLD 3 " into the D8050. The next instruction WTOB separates each of the characters into its own register, this is repeated with a second set of registers. the MOV H0D is moving a Hex value for a CR into a register. then the last line combines all of the characters back into 1 string of 51 characters.
