Tag Variables
Valid tag variable names and address ranges are shown in the DeviceNet Protocol dialog box when you
configure the protocol.
The number of Input and Output words and the addressing 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.
Byte Addressing Example
Input Words = 127, Output Words = 127, Input start address = 0, Output start address = 0.
