Word Addressing
In this configuration example, Input Words are set to 64, Output Words are set to 64 and Addressing is
set to Word Boundaries.
When the OK button is clicked, the following DeviceNet Protocol dialog box will appear. The valid
address ranges are shown for all types of variables.
The number of Input and Output words selected will determine the valid address range limits for each
variable type. The variable type names are fixed and are displayed in a cell corresponding to the
addressing type. For example, in the following dialog box, the number of Input Words is set to 64. The
variable name for Input Words is IW and the range for 64 words is IW0 to IW63. Output Words are
also set to 64, so the variable name is QW and the range is QW0 to QW63.
