48 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 need to 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 49.

Step: See page:

❑ If You Need to Conserve EtherNet/IP or ControlNet Network

Bandwidth

❑ Add the Scanner to the I/O Configuration Folder 50

❑ Define the Properties of the Scanner 51

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.
