Predict System Performance

This chapter describes how to predict the performance of your EtherNet/IP

network-based control system and how to enhance that performance

Topic Page

System Prediction Goals 80

Performance Calculations 83

Example: Predict System Performance 90

IMPORTANT

This chapter explains how to calculate system performance with data from

your system in specific equations. However, you can also use the EtherNet/IP

Capacity Tool, an online tool, to predict system performance.

The EtherNet/IP Capacity Tool and the IAB Tool are intended to help you in the

initial layout of your EtherNet/IP network by calculating resources, for

example, connections, packet rate capacity, used by a proposed network.

Download the EtherNet/IP Capacity Tool at the Integrated Architecture Tools

website: http://www.rockwellautomation.com/solutions/

integratedarchitecture/resources3.html#enetpredict.

The EtherNet/IP Capacity Tool calculates a rough estimate of the packet rate

capacity. Packet rate capacity varies depending on the specific conditions of

each application.

For a more detailed analysis of a proposed network, use RSNetWorx for

EtherNet/IP software.
