Diagnostic Overview Statistics
The Diagnostic Overview web page presents a summary of the current
configuration and overall status of the module.
1. Review the Module Resource Utilization table to monitor your
CPU utilization.
2. Review the CIP Connection Statistics (All Ports) table to monitor CIP
connection usage.
If the CPU
utilization rate is
Then
0...80% No action is required.
Important: This is the optimal rate.
Greater than 80% • Take steps to reduce your CPU utilization. See Internet Group Multicast Protocol on
page 144.
• Adjust your connection’s requested packet interval (RPI).
• Reduce the number of devices connected to your module.
Important: Your EtherNet/IP communication module can function at 100% CPU capacity,
but at or near this rate, you run the risk of CPU saturation and performance problems.
