12 Communications Performance and Communications Load
The percentage of the allowed tag data link bandwidth being used (Usage of Capacity) increases to
77.83% for devices 192.168.250.1 and 192.168.250.10, which indicates that the RPI is set to a
higher speed for these devices' connections.
The Usage of Capacity values also indicate that the Usage of Capacity has increased (from 33.64%
to 37.83%) for all of the other devices, which connect with devices 192.168.250.1 and
192.168.250.10.

In this case, if there is no multicast filter, the value becomes 104.50%. If there is no multicast filter for
an Ethernet switch, communications errors may occur depending on the communications load of the
EtherNet/IP Unit.
Method 3: Changing the Packet Intervals (RPIs) of Only Specific Connections
In this example, we want a faster tag data links for just a particular connection of device
192.168.250.1. Double-click device 192.168.250.1 in the Network Configuration Window.
