Can you explain pros-cons if the total loading is 72% and cyclic loading in below 40%.
Cyclic Load (Tasks):
Cyclic load displays the percentage of the controller CPU power used for application execution of all tasks. If the cyclic load exceeds 70% in the controller a so-called load balancing is initiated automatically. The intervals for all tasks, except the time-critical task, are then generally increased to limit the cyclic load to 70%.

1 The base load relates mainly to communication. It is important to consider CPU load if communication handling is vital to the application. Running at the maximum cyclic load will result in poor capacity and response times for peer-to-peer and OPC Server communication
