Number Systems
There are four numbering systems used with programmable controllers.
They are:
Decimal
Octal
Binary
Hexadecimal
These numbering systems differ by their number sets and place values.
The decimal numbering system uses a number set made up of ten digits:
the numbers 0 through 9. All decimal numbers are composed of these
digits. The value of a decimal number depends on the digits used and the
place value of each digit.
Each place value in a decimal number represents a power of ten
(Figure B.1), starting with 100. The value of a decimal number is
determined by multiplying each digit by its corresponding place value and
adding these numbers together.
