Parameterizing tool

The parameterization tool has an easy to understand and easy to use Windows user interface. The following functions are available:

• Block diagram:
  With a block diagram, the controller can be easily parameterized. The individual functions can be connected or disconnected by means of software switches.
• Test functions via loop display and trend curves:
  The loop display can be used for operating and monitoring the controller for test purposes. The graphic plotter records up to four signal curves. This is particularly useful for verification of the quality of the process and supports fault diagnosis.
• Wizard for control loop optimization:
  The wizard guides the user step by step through the controller optimization procedure, thus enabling rapid startup without requiring control-specific expertise.
• Variable transient response:
  The transient response of the control loop can be selected such that the control loop responds with an overshoot of approximately 10 % for an enhanced dynamic response. If this is not desired, the controller can be optimized so that no overshoot occurs.
• Context-sensitive, user-friendly Help:
  Appropriate assistance is immediately available at every point in the program if required.

Standard Function Blocks

For the standard function blocks, the controller structure is prefabricated and the data structure is defined. The following functions can be connected and disconnected by software switches:

• Setpoint-value processing with setpoint-value generator, time scheduler, scaling, function call, limiting of setpoint-value slope (acceleration-rate limiter) and limiting of setpoint value
• Actual-value processing with scaling, smoothing, square root, function call, limit-value monitoring and monitoring of the actual-value slope
• System deviation processing with deadband and limit-value monitoring
• PID algorithm, with and without position feedback on the step-action controller
• Control output processing with manual or automated system transfer, manual value generator, FC invocation, limiting of the setpoint value, slope and scaling.
