Here you find the sample plant used as SIMIT simulation model.

This module is intended to acquaint readers with the sample plant / multi-product line and multiple stream line / multiple path line used in the subsequent modules.

In this chapter, the students learn how an automation system works. They will be able to configure the selected hardware in the hardware configuration of PCS 7 and check it for consistency. Important settings will be parameterized so that from this data, the process control system PCS 7 automatically sets up in the automation stations all blocks necessary for communication between sensors, actuators and the control level.

The students learn to structure an automation project according to technical aspects. A project structure called Plant Hierarchy (PH) is implemented by setting up hierarchy folders. In the folders of this plant hierarchy, CFCs and SFCs are then stored for the automation systems, graphs and reports for the operator stations as well as supplementary documents (such as subsystem descriptions, process tag sheets, planning documents from other applications such as Word, Excel, etc.). A well-planned plant hierarchy facilitates locating objects and is the prerequisite for the reuse of generic solutions as well as automatic generation mechanisms.

After working through this module, the students will be able to define and classify the term 'individual drive function‘ within the scope of object-oriented software structuring. They understand the concept, the structure as well as the functional method of individual drive functions, they know typical individual drive functions and their implementation in PCS 7.

After working through this module, the students are familiar with the basic requirements for functional safety. They will learn methods to identify potential danger as well as to evaluate the risks resulting from it. They will know methods and design-concepts to safeguard plants with the means of process control engineering. They will learn the basic connections for interlocking controls.

In this chapter, the students are familiarized with the essential components and requirements for a block for the continuous control of process variables. This will enable them to set up and configure temperature control using the blocks PIDConL and PULSEGEN.

The students learn to identify recurrent structures and to design templates. They know the difference between a process tag type and a model. They will be able to create and implement both. This allows the students to implement many similar process tag types or subunits in PCS 7. They become familiarized with the process object view and are able to use it to represent parameters system-wide, and change them if needed.

The students will be able to successfully implement sequential controls by using sequential function charts. They will understand the structure and the operating principle of sequential function charts and will be acquainted with corresponding design methods. Their knowledge regarding operating modes and protective measures will be expanded for sequential control systems. The students understand the interaction between the programs and basic automation and sequential controls. They know how to generate sequential controls in PCS 7.

After working through this module, the students will be able to design and implement a graphic user interface for efficient process monitoring and control. To this end, they will be familiarized with the objective of process management. They understand the basic concepts of representation and are acquainted with different representation techniques. This enables the students to generate a graphic user interface that is useful and efficient.

In this module, the students are familiarized with the fundamentals of an alarm system. They understand the purpose and the areas of application of alarm and signaling systems, and they know the requirements for such systems resulting from this. They are familiarized with the possibilities of representation, and interactions with messages and alarms. This enables the students to design a suitable and useable alarm management in PCS 7.

After working through this module, the students know the basic requirements and objectives of archiving. They are able to apply different types of archiving to process data and messages. The students know how suitable cycles can be determined for time controlled archiving and they also know the criteria according to which event controlled data archiving is executed. They know the options that PCS 7 provides.

After working through this module, the students have additional knowledge regarding the design of the user interface of an operator station. They are able to make additional information available on the detail level. To this end, they use adapted message lists and trend curves. The students are able to combine created composites into a user defined object and redesign existing objects as user defined objects. These objects can then be made available for reuse.

In this chapter, the students learn to integrate automation systems by diverse manufacturers into higher level programs of the plant control level. The required fundamentals for setting up OPCs and the method of functioning as well as the integration possibilities by means of PCS 7 are explained.

In this section, students will learn how to hierarchically model an industrial batch process. They can define recipes for controlling batch process cells and manufacturing batch products, including the necessary process steps, and then implement these in the PCS 7 control system.
