8. Click the Connection tab.
9. In the ‘Requested Packet Interval (RPI)’ box, set the value to 2.0
milliseconds or greater (default is 20.0 milliseconds).
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 adapter from
communicating with the RSLogix 5000 project. When the ‘Major Fault
On’ box is checked, a major controller fault will occur when the adapter’s
connection fails while the controller is in the Run mode. For this example,
leave the ‘Inhibit Module’ and ‘Major Fault On’ boxes unchecked.
Unicast support has been added to RSLogix 5000 software, version 18.00
(or later). Unicast is recommended whenever possible. For the benefits of
unicast operation, see
Preparing for an Installation on page 17 .
10. Click OK.
The new node (‘My_PowerFlex_755_Drive’ in this example) now appears
under the bridge (‘My_EtherNet_IP_Bridge’ in this example) in the I/O
Configuration folder. If you double-click on the Input and Output
Controller Tags (
Figure 9 and Figure 10 ), 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 via the controller’s ladder logic.
