When the Detail Button is clicked in the Usage of Device Bandwidth Area, it is apparent that the per-
centage of the allowed tag data link bandwidth being used by each device’s tag data link (Usage of
Capacity) is 33.67%, as shown in the following dialog box.
Method 1: Same Packet Interval Setting for All Connections
The percentage of the allowed tag data link bandwidth being used (Usage of Capacity) was 33.67%
with the RPI set to 10 ms for all of the connections, so the RPI will be set to 4 ms, with a target of
80% or less of the allowable bandwidth.
Click the Set Packet Interval (RPI) Button at the bottom of the Usage of Device Bandwidth Dialog
Box to display the Set Packet Interval (RPI) Dialog Box. Input 4 ms as the new RPI value, then click
the
OK Button.
