Labtech Control is a complete, integrated system that provides a comprehensive set of monitoring and control functions, including process monitoring, process control, real-time operator interface and display, on-line analysis and open architecture networking.
Labtech Control is a comprehensive industrial software package featuring an extensive library of I/O drivers, which allows users to create, simulate, test, and run control strategies on OMEGA's hardware interfaces, including plug-in boards and stand-alone systems. Labtech Control interfaces to a wide variety of process variable types, such as analog voltage and current, discrete I/O, thermocouple, RTD, strain gage, counter, and frequency inputs. Other variable types include time, replay of stored or theoretical data, and calculated variables. Analog and digital outputs, as well as pulse outputs, are also supported.
Process data can be monitored on a continual basis. For more efficient operation, when a very large number of variables are present, you can set up the system to collect data only on those variables being displayed or logged on an active trend line or graphics window.
Labtech Control software also performs alarm and limit monitoring. Alarms can be triggered when a variable reaches or passes a predetermined value, or as a result of a calculated variable or operator action. All systems support multiple alarm states: Hi-Hi, high, normal, low and Lo-Lo, which can be displayed on the computer monitor and logged to disk. The system can be configured so that when an alarm occurs, the operator is notified and must acknowledge the condition.
Labtech Control provides a comprehensive series of control functions. Alarm and bang-bang control features allow for the turning on and off of equipment for closed-loop control or to indicate alarm conditions. PID loops provide closed-loop control for constant or variable setpoints. Setpoints can be entered through the keyboard, automatically through on-line calculations, or as a preset schedule of values stored on disk. Control loops have a block-structured architecture. Each control block implements individual control algorithms for specific variable inputs and control outputs. Cascade control-the ability to have the output of one control loop act as the input to another-provides you with an added degree of freedom when configuring your control strategy.
Realtime Vision software, included with Control, provides the user with an object-based graphic interface, for ease of use. The combination of Control and Vision gives you the power of client-server architecture for your data acquisition and control system. Vision and Control can execute on the same PC, or on different computers across a network. As values in Control change, Vision displays the changes. Vision is completely interactive, so you can change the Vision display on-the-fly. Vision also gives you knobs, switches and sliders that can be used to make adjustments to Control as it is running.
Automatic tuning of PID loops is an advanced control technology that has been bundled into some single-loop controllers and made available as options on high-end distributed control systems. The autotuning algorithm set that has been adopted by many process control features has been incorporated into Control, providing unmatched capabilities in PC-based data acquisition and control.
With the standard Control, operators can elect to retune a loop at any time, without shutting down the control loop. This autotuning method provides excellent noise immunity. Continuous autotuning, standard on Control Pro, operates without operator intervention or process disturbance. The process is continuously monitored, and new, revised PID constants are fed to the controller as necessary. The result is true self-tuning control.
