Description
The following program converts digits 1 to 3 of data from DM 0020 to bit posi-
tions and turns ON the corresponding bits in three consecutive words starting
with HR 10. Digit 0 is not converted.

Ladder Symbols
DMPX(77)
SB
R
Di
The rightmost two digits of Di must each be between 0 and 3.
All source words must be in the same data area.
DM 6144 to DM 6655 cannot be used for SB, R, or Di.
When the execution condition is OFF, DMPX(77) is not executed. When the
execution condition is ON, DMPX(77) determines the position of the highest
ON bit in S, encodes it into single-digit hexadecimal value corresponding to
the bit number of the highest ON bit number, then transfers the hexadecimal
value to the specified digit in R. The digits to receive the results are specified
in Di, which also specifies the number of digits to be encoded.
