14-2-4 Changing the RPI
You can check the usage of capacity offline without multicast filtering against the tag data link’s allow-
able bandwidth by following the procedures in 14-2-1 Checking Bandwidth Usage for Tag Data Links.
The usage of capacity without multicast filtering can be adjusted against the tag data link’s allowable
bandwidth by changing the packet interval (RPI).
If the required communications performance cannot be achieved by changing the settings, re-evaluate
the network starting with the network configuration.
1
Make the required settings in the Network Configurator’s Network Configuration Window.
2
Click the Detail Button in the Usage of Device Bandwidth Area at the bottom of the Network
Configuration Window.
The Usage of Device Bandwidth Dialog Box will be displayed.
The Usage of Capacity (without multicast filter) column will show the percentage of the allowed
tag data link bandwidth being used, and the Mbit/s (without multicast filter) column will show the
network bandwidth being used.
