Determine the Address of
DeviceNet Data
When you add the scanner to the I/O configuration of the controller,
RSLogix 5000 software automatically creates a set of tags for the input, output,
and status data of the network:
The tags for your DeviceNet data follow this format:
input data from the scanner
status data from the scanner
output data for the scanner
The scanner memory uses this format: Which is this tag in the controller
