Process Control Software

The HMI is responsible for displaying process sensor and controller data to the user, and for historical logging of data. These actions allow the user to make decisions so new process set points can be entered. The data displays are achieved through numerical displays and other visual indicators, e.g., a valve colored green would be open. The HMI design must carefully consider the appropriate display methods and the organization of the data. With over 200 process variables in the AIMS, it would have been easy to overwhelm the operator with data. Thus, most control actions are done pictorially by clicking on a valve or another object. In this way, the data is displayed in close proximity to where the user can enter new process set points.

Data handling and process control software program for wastewater treatment plants. Requires Apple II. 

All reaction parameters including volume rates of the hydrogen, organic and aqueous phase as well as the partial pressure of hydrogen and the reaction temperature are recorded on a PC and can be controlled by process control software, which was developed in the working group. 

The chamber was designed by D. Natusch, University Leipzig (Figs. 7.2 and 7.3) and the process control software was written by H. Hochmuth... 

The reader is referred to the NCCLS standard AUT03-A, which is described in the following and in particular to the Functional Control Model (Section 4.2), which describes the relationships between the LIS, LAS, and various devices. In this model, and throughout the series of NCCLS automation standards, the term LAS represents the computer system that controls the automation system, not the actual automation hardware. Most often, it is the LAS that has the requisite process control software to support automation. The functional control model, which is depicted in Figure 11-19, supports analytical instruments that may be physically attached to the automation system and analyzers that may not be attached but are still interfaced to the LIS. The model does not give dominance to either the LIS or the LAS, but rather allows for essential information flows in either direction to make the most efficient use of the strengths of each system. 

This list of tasks is not necessarily complete but demonstrates the complexity of the software engineering task of integrating automation in a laboratory. Although the functions of the LIS and LAS are often provided on separate computers, they may also be integrated on a single computer. Several manufacturers (e.g., MDS AutoLab, Odysis, and Zymark) have process control software that can manage many functions in an automated laboratory. However, the... 

The detection and diagnosis tasks can be carried out on the process measurements to obtain critical insights into the performance of not only the process itself but also the automatic control system that is deployed to assure normal operation. Today, the integration of such tasks into the process control software associated with Distributed Control Systems (D-CS) is in progress. The technologies continue to advance, especially in the incorporation of multivariate statistics as well as recent developments in signal processing methods such as wavelets and hidden Markov models. 

This section provides an overview of the system hardware, the design principles associated with the process control software, and a summary of the various process control human-machine interfaces. 

This requirement is facilitated by specifically designed process control software which has the following features ... 

The online process control software provides a simple interface between the analyzer, the user, and the control room. 

The core element is a frequency-controlled motor and a holder for the rotating substrates (e.g., disks). Depending on the application, liquid, optical, and possibly electrical interfacing between rotating onboard components and stationary lab-frame components such as dispensers or detection units have to be incorporated. A process control software has to synchronize events such as liquid handling or optical readout to the periodic motion of the substrate. Figure 14 shows device concept of the LabCD platform.

For a DCS to function properly, a concerted effort of many software tasks is required (Miklovic, 1993 Liptak, 2005). The core of each network node must be a rehable real-time multitasking operating system that is divided functionally into different tasks—that is, communication between DCS nodes, data acquisition and control, operator interface, process control software, system utihty hbraries, and report generation. All these tasks are interdependent and share process data stored in a database. Because all network nodes must possess communication capabihty while maintaining a local database, these tasks may be distributed in different nodes. 

Section 9.4 introduces K-RAMP from its process perspective. It is explained how the approach determines reusable elements of forerunner products or of existing process plans for the creation of forerunner products. Based on this process view on K-RAMP, the requirements to be satisfied are introduced in Sect. 9.5. In Sect. 9.6, the underlying ontology models and the software architecmre of the knowledge base are described. Section 9.7 is completing the description of the approach by addressing the reuse and adaptation of semps of the process control software (further described as production-IT). This part is particularly essential as process control is cmcial in order to meet the quality targets at the end of the ramp-up phase.
