 Fast logic scan (approx. 10ms) is required to perform
motor or motion control.
 Control loops require deterministic scan execution.
perform motor or motion control at a speed of 100 to 500 ms
 Redundancy may not be cost justified.
 System redundancy is often required.
 System can be taken offline to make configuration.
 Online configuration changes often required changes.
 Analog Control: Simple PID only.
 Analog Control: Simple to advanced PID control up to
Advanced Process Control.
 Diagnostics to tell you when something is broken.
 Asset Management alerts you to what might break before
it does.
