ScadaPro features an optional
PID Controller Processor.
The PID (Proportional-Integral-Derivative) algorithm is
used to drive a measured variable to a preset value or setpoint. A
common form of such a closed loop system is temperature control of a
process. More generically, the PID module provides control for analog
outputs and for pulse-width and pulse-modulated digital
outputs.
ScadaPro's simple and intuitive interface allows you to
set up one or multiple windows for configuration and monitoring of
control loop(s). A block diagram, bar graph, and strip chart display for
each control loop let you view parameter change and effect dynamically.
Features include:
- Control for closed loop systems.
- Block diagram, bar graph, and strip chart display for
each control loop.
- Dynamic viewing of change and effect.
- Velocity and position
algorithms supplied.
- Support for user-supplied algorithms (COM
DLL's).
- Bumpless transfer between manual and automatic
modes.
- Anti-windup reset.
- Direct or reverse acting
output.
- Deadzone range of plus(+), minus(-), or
both.
- Synchronous control based on response
time of input channels scanned from DAQ devices.
- Bumpless transfer to prevent integral
wind-up.
- Direct entry of parameter values with a
mouse-click on the displayed value.
