8. On the New Module window, click the Connection tab.
9. 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.
The “Inhibit Module” box, when checked, inhibits the module from
communicating with the RSLogix 5000 or Logix Designer project. When
the “Major Fault On…” box is checked, a major controller fault will occur
when the module’s connection fails while the controller is in the Run
Mode. 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.
10. Click OK on the New Module window.
The new node (“PowerFlex 525-E2P-Multi PowerFlex_52X_Drive-Multi”
in this example) now appears under the
icon in the I/O
Configuration folder. If you double-click on the Input Controller Tag (see
Controller Input Tags on page 97 ) and Output Controller Tag (see
Controller Output Tags on page 98 ), you will see that module-defined
data types and tags have been automatically created. Note that all tag
names are defined for each drive. After you save and download the
configuration, these tags allow you to access the Input and Output data of
the drives using the controller’s ladder logic.
