Rory,
In the ind block you can have RI0001 connected to your MAIN block
analog out (ie. PNT_1) where you are representing character pair 'AB'
as 0x4142.
RI0001 will be 16706.
Divide RI01 by 256 and truncate to get left hand character value of 65
(decimal representation of 0x41).
RI0001 MOD 256 will give you right hand character value of 66 (decimal
representation of 0x42).
A subroutine for mapping these decimal equivalents to ascii text should
be simple, ie.
IF (char = 65) THEN
char_out := "A";
ELSEIF (char = 66) THEN
char_out := "B";
ELSEIF (char = 67) THEN
char_out := "C";
etc...
