8. On the New Module screen, click the Connection tab.
9. In the ‘Requested Packet Interval (RPI)’ box, set the value to 5.0
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. We
recommend keeping the default value of 20.0 milliseconds.
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, but
keep the ‘Use Scheduled Connections over ControlNet’ box checked.
10. On the New Module screen, click the Drive tab.
