Rate of Response
Mark VIe and Mark VIeS controllers can run at a variety of frame rates to meet the application needs of the industrial control solution. Control systems are tuned
accordingly, based on a variety of factors including: complexity of controller application logic, processor type, and number of I/O and other interfaces used. The following
diagram provides an example of typical processes that occur during a single controller frame in sequence.
