Chapter 4 Configuring the I/O

6. Click the Connection tab.

7. In the “Requested Packet Interval (RPI)” box, set the value to 2.0

milliseconds or greater. This value determines the maximum interval that a

controller should use to move data to and from the adapter. To conserve

bandwidth, use higher values for communicating with low priority devices.

For this example, leave the “Inhibit Module” and Major Fault On…” boxes

unchecked.

The “Use Unicast Connection over EtherNet/IP” box is checked by

default. This is the recommended setting. When this box is unchecked, the

adapter will send multicast messages on the I/O connection. In this case,

the adapter and the EtherNet/IP bridge must be on the same subnet.

8. Click OK. The new node

(“ETHERNET-MODULE_PowerFlex_52X_Drive” in this example)

now appears under the icon in the I/O Configuration folder. If

you double-click on the Input Controller Tag (see Input Image Controller

Ta g s on page 60) and Output Controller Tag (see Output Image

Controller Tags on page 60), you will see that module-defined data types

and tags have been automatically created. After you save and download the

configuration, these tags allow you to access the Input and Output data of

the drive using the controller’s ladder logic.
