206 Conversion Instructions
You should convert BCD values to integer before you manipulate them in
your ladder program. If you do not convert the values, the controller
manipulates them as integers and their value may be lost.

TIP
If the math register (S:13 and S:14) is used as the source
for the FRD instruction and the BCD value does not
exceed four digits, be sure to clear word S:14 before
executing the FRD instruction. If S:14 is not cleared and a
value is contained in this word from another math
instruction located elsewhere in the program, an
incorrect decimal value is placed in the destination word.
