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.
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.
Important: Unicast support has been added to RSLogix 5000 software,
version 18.00 or later. However, to also support unicast, the
controller firmware must be version 18.00 or later. Unicast
is recommended whenever possible. For the benefits of
unicast operation, see
