9. In the ‘Requested Packet Interval (RPI)’ box, set the value to 5.0
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 option module. 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 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.
10. Click OK.
The new node (‘My_PowerFlex_755_Drive’ in this example) now appears
under the bridge (‘My_ControlNet_Bridge’ in this example) in the I/O
Configuration folder. If you double-click the Input and Output Controller
Tags (
Figure 8 and Figure 9 ), 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.
