 Converts the data of lower “ n” digits (one digit consists of four bits) of
16-bit data that begins with the device
S
into the ASCII code and
stores the result into four point devices that begin with the device
D
.
 Program Example
HEX D10 K4D20
X0
• 16-bit conversion (M1161 OFF)
(D10) = 0ABC H ‘0’ = 30H ‘ 1’ = 31H ‘ 5’ = 35H
(D11) = 1234 H ‘ A’ = 41H ‘ 2’ = 32H ‘ 6’ = 36H
(D12) = 5678 H ‘B’ = 42H ‘ 3’ = 33H ‘ 7’ = 37H
‘C’ = 43H ‘ 4’ = 34H ‘ 8’ = 38H
