Configure FLEX I/O Digital Modules on a DeviceNet Network
Add the Scanner to the I/O
Configuration of the
Controller Using RSLogix
5000 Software
To access the data of your network, add the scanner to the I/O configuration of
the controller.
To add a scanner:
If You Need to Conserve EtherNet/IP or ControlNet Network
Bandwidth
The default configuration of the scanner gives you the maximum amount of
input, output, and status data.
If the scanner communicates with the controller via an EtherNet/IP or
ControlNet network and you must conserve bandwidth over that network,
consider reducing the input, output, or status sizes.
• Set the input and output sizes = the number of input and output DINTs in
the scanner that actually store device data.
• If you are
not
going to use all the status information, set the status size to
the minimum required. See Set the status size for a scanner on page 51.

Define the Properties of the Scanner
EXAMPLE
Set the status size for a scanner
• If you want to
only
use the ASCII representation of
scanner status/display, then set the Status Size = 10.
• If you also want to read the status code of the scanner, set
the Status Size = 11.
