4 If the bandwidth usage rate is not set as desired even after the above operation, re-evaluate
the network configuration,considering the following points. (Refer to 15-2-3
Adjusting Device
Bandwidth Usage on page 15-10.)
• 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 15-2-1 Checking Bandwidth Usage for T
ag Data Links on page 15-8.
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.
