Adjusting the Communications Load
Section 10-2
Example Conditions
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.
By default, the packet intervals (RPI) are set to 10 ms for all of the connec-
tions. The devices’ IP addresses range from 192.168.250.1 to
192.168.250.20.
Checking the Device
Bandwidth Usage
When the Detail Button is clicked in the Usage of Device Bandwidth Area, it is
apparent that the percentage of the allowed tag data link bandwidth being
used by each device’s tag data link (Usage of Capacity) is 39.67%, as shown
in the following dialog box.
IP address:
192.168. 250.1

10 CS1W-EIP21 Units + 10 CJ1W-EIP21 Units = 20 Units total
The RPI is 10 ms (ethernet default) for all connections.
