DeviceNet Addressing
The addressing of the Reader DeviceNet I/O requires 2 bytes. The
following tables show the byte and bit address for each of the inputs
and outputs. Use these charts when setting up the DeviceNet
scanner.
I/O data is addressed and sent to other DeviceNet devices through a
DeviceNet scanner (Catalog No. 1771-SDN or 1747-SDN). To
configure the scanner, you will need to provide the size of the I/O
data, the beginning byte and bit number of the data and the
destination of the I/O data.
