Chapter 4 Configuring the I/O

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.
