BCC calculation and 8bit XOR

got_fr

Hi,

is there an SFC SFB block to calculate an 8bits BCC ?
if not is there an 8 bit Xor to do the bcc manually ?

Thank you
Olivier

8 bit bcc is for me an 8bitXOR of the data i want to "checksum"

i don't know the list langage and in contact langage i didn't find the way to do xor with byte var. i'll try your solution

thanks
