In this chapter, we further investigated the project organizational units we have been using throughout this book. We detailed the way that a Logix controller executes tasks and how the CPU divides its time based on priority. We introduced the overhead time slice feature and emphasized its importance when optimizing a Logix application. Finally, we investigated methods within the Logix platform to monitor and troubleshoot performance issues. We can now troubleshoot and optimize Logix project performance on larger solutions.
In the next chapter, we will dig deeper into troubleshooting controller issues and faults.
