Packet Interval (RPI) Setting Examples

Example Conditions
• Split the network.
5. Check the bandwidth usage again.
If the connection settings have been changed, click the Detail Button in the
Usage of Device Bandwidth Area at the bottom of the Network Configura-
tion Window. Verify that the allowed tag data link bandwidth used (Usage
of Capacity) is less than 100%.
It is particularly important to check the Usage of Capacity when an individ-
ual connection's packet interval (RPI) setting was changed without using
the Set Packet Interval (RPI) Button at the bottom of the Usage of Device
Bandwidth Dialog Box.
6. Run user tests to verify that there are no problems with the new settings.
The following examples explain how to calculate the packet intervals (RPI) in
the following network configuration.
Connections
In this example, there are 10 CS1W-EIP21 Units and 10 CJ1W-EIP21 Units
for a total of 20 devices connected in the network. Each device has one 100-
word tag for transmission and nineteen 100-word tags for reception, so that
the Units exchange data mutually.
