Performance Factors

There are many factors that affect the timing of I/O as it flows through the system. Primary factors include:
•
CPU Sweep Time
•
Configured PROFINET IO Update Rate(s)
•
Number of PROFINET IO Devices
•
Number of IO modules
•
Network latency and loading (for example, switching hardware, additional non-PROFINET network traffic)
•
I/O Module Filter Times
When designing a PROFINET IO system, consider and weigh these factors appropriately to achieve an optimal
IO system for the application.
