the network configuration,considering the following points. (Refer to 12-2-3 Adjusting Device
Bandwidth Usage on page
12-10.)
• Reduce the number of nodes and connections
• Split the network
5 Check the bandwidth usage rate again.
After you change the connection settings, click the Detail Button in the Usage of Device
Bandwidth Area at the bottom of the Network Configuration Window to check the bandwidth
usage as described in 12-2-1 Checking Bandwidth Usage for Tag Data Links on page 12-

It is important to check the bandwidth usage particularly after you change the RPI values for
individual connections, instead of setting the same RPI for all the connections.
6 Run user tests to verify that there are no problems with the new values.
