PROFINET IO Performance Examples 

Note:

  The configurations and performance numbers shown here are examples; Actual 

performance timings will vary depending on your exact configuration and network setup. 

This section presents various PROFINET IO systems and their measured I/O performance for a 
simple 16 point Discrete I/O Loopback.  As these systems are not identical in their configuration or 
setup, additional details of each system configuration are in a section following the table below. 

The I/O Loopback measurements were done by wiring the outputs of a discrete output module 
directly to the inputs of a discrete input module, and using Ladder Logic to measure the time 
difference between setting the outputs and reading the same data on the corresponding inputs.  
Proficy Machine Edition was attached to the RX3i during testing.  The average, minimum, and 
maximum loopback times were captured from a 4 hour sample period.  In addition, since the CPU 
sweep time is a primary factor in the accuracy and precision of the I/O Loopback times recorded, the 
average and maximum CPU sweep times for each system are given. 

Note:

  CPU Sweep time variations between systems are not completely a function of varying 

PROFINET IO. It was also influenced by variations in logic executed and main rack 
configurations.
