P ROPERTIES dialog box.
5 In the C ONNECTION tab, the Requested Packet Interval (RPI) value represents
the time interval at which the module will attempt backplane communication
with the processor. This value should not be set to less than 1 millisecond.
Values between 1 and 10 milliseconds should work with most applications. If
the module is installed in a Remote chassis and accessed via ControlNet, the
RPI must not be set to a value lower than the ControlNet Network Update
Time (NUT). Doing so will cause scheduling errors in RSNetworx for
ControlNet.
