DAPL Process Control Commands
Process control commands are used for system monitoring and regulation.
A special command provides control of processing priority, allowing intensive
number crunching tasks and responsive real-time tasks to coexist.
- Establish the execution priority of all tasks in the group.
Real-time and control commands generate responses to individual events with
minimum time delay.
- PID (Proportional - Integral - Derivative) feedback control, plus several common extensions.
- Pre-computed smoothed input transitions for PID and feedforward controls.
- Perform shutdown overrides to safe output level before shutdown.
- Convert amplitude data to pulse width modulation data for on-off
control of slow analog processes.
- Software based decoding of optical encoder signals for relatively slow
- Post a digital alarm if the signal level exceeds an
adjustable operating range.
