Data Types for Advanced Instructions
When using move, data comparison, binary arithmetic, Boolean computation, bit shift/rotate, data conversion, and coordi-
nate conversion instructions for the OpenNet Controller, data types can be selected from word (W), integer (I), double
word (D), or long (L). For other advanced instructions, the data is processed in units of 16-bit word.
Decimal Values and Hexadecimal Storage
The following table shows hexadecimal equivalents which are stored in the CPU, as the result of addition and subtraction
of the decimal values shown:
Data Type Symbol Bits
Quantity of Data
Registers Used
Range of Decimal Values
Word (Unsigned 16 bits) W 16 bits 1 0 to 65,535
Integer (Signed 15 bits) I 16 bits 1 –32,768 to 32,767
Double Word (Unsigned 32 bits) D 32 bits 2 0 to 4,294,967,295
Long (Signed 31 bits) L 32 bits 2 –2,147,483,648 to 2,147,483,647
