In our example, we typed 4 in the Input Size and Output Size boxes
because the Operating Mode Switch on the module is set to “Single”
(default) and parameter 22 (MDI I/O Cfg) is set to “Drive 0” (only
one drive being connected). Logic Command/Reference uses 2
words and Logic Status/Feedback uses 2 words. The additional 2
words for the inputs are for ENBT overhead.
Note: For instructions on configuring the I/O for the module
(parameter 22 (MDI I/O Config)) refer to chapter 4, Configuring the
Module.

Step 6.
In the Requested Packet Interval (RPI) field, set the
value to 5.0 milliseconds or greater. This value
determines the maximum interval that a controller should
use to move data to or from the module. To conserve
bandwidth, use higher values for communicating with low
priority devices.
