5-17 Conversion Instructions
The Conversion Instructions convert word data that is in one format into another
format and output the converted data to specified result word(s). All of these
instructions change only the content of the words to which converted data is be-
ing moved, i.e., the content of source words is the same before and after execu-
tion of any of the conversion instructions. Refer to 5-26 Time Instructions for
instructions that convert between different time formats.

When the execution condition is OFF, BIN(100) is not executed. When the
execution condition is ON, BIN(100) converts the BCD content of S into the nu-
merically equivalent binary bits, and outputs the binary value to R. Only the con-
tent of R is changed; the content of S is left unchanged.

Binary
BIN(100) can be used to convert BCD to binary so that displays on Programming
Devices will appear in hexadecimal rather than decimal. It can also be used to
convert to binary to perform binary arithmetic operations rather than BCD arith-
metic operations, e.g., when BCD and binary values must be added.
S must be BCD.
Note Refer to page 101 for general precautions on operand data areas.
Flags ER (A50003): S or content of
*
DM word is not BCD when set for BCD.
EQ (A50006): 0 has been placed in R
N (A50008): OFF
Example When CIO 000000 is ON in the following example, the content of D00010 is con-
verted from BCD to binary and stored into D00011. The content of D00010 is left
unchanged.
