13-1-3 Packet Interval (RPI) Accuracy

The send processing delay occurs in the built-in EtherNet/IP port when data packets are sent once
each packet interval (RPI). This delay varies with the RPI error shown in the following graph, so the
send processing delay time is the maximum value for each RPI.
