Simatic PCS 7
Simatic PCS 7 is a process control system from Siemens , which is based on modular Simatic hardware and software components from the Totally Integrated Automation (TIA) system spectrum, which are coordinated in terms of functionality . It is the successor system to Teleperm M and was gradually introduced and further developed in the 1990s. Version 9.0 was introduced in 2017. The standard components include PC, controller, communication and decentralized peripherals. It is used in process industries such as the chemical industry, pharmaceutical industry and food industry for the management of the main production process , but also for secondary, upstream and downstream processes such as B. wastewater treatment and energy distribution are used. It also supplies data to higher-level ERP systems .
Product features
As a homogeneous and integrated overall system ( Distributed Control System , DCS) with central engineering and a common database, Simatic PCS 7 enables end-to-end automation of both manufacturing and process engineering processes and is used in the process, manufacturing and hybrid industries. Not only the documentation, but also the quality assurance is provided for the overall system. In contrast to this, there are SCADA solutions ( Supervisory Control and Data Acquisition ) that are based on combined individual components (sometimes from different manufacturers) and the scope of functions is not coordinated with one another, which means more extensive data management, more complicated function additions, the use of individual programming tools and communication tools as well as separate Makes quality assurance necessary for each individual component. With the integrated DCS approach, all functions are contained in the function and system-tested individual components with which an overall system can be built.
Basic functions
The Simatic PCS 7 process control system is operated using graphical interfaces, e. Sometimes with context-dependent, user-specific views. All measured values , messages and alarms that are to be available over a longer period of time are stored and managed in a central archive server.
Due to the modularity of hardware and software components, the process control system can be used flexibly in different plant sizes and adapted to changing requirements. This allows the expansion and expansion of plants. The capacities range from small individual systems (approx. 160 measuring points ) to multi-user systems ( client-server architecture ) consisting of several operator stations and servers in a system network (over 100,000 measuring points).
In addition, the system can be combined with components from other manufacturers and integrated into existing infrastructures, as the system architecture and communication are open. There are also programming and data exchange interfaces for user programs and for importing and exporting data, texts and graphics. Process data are accessible and company-wide thanks to standardized interfaces. Communication within the system takes place via the industrial standards Ethernet and PROFIBUS , but in some cases at the field level still via the AS-Interface .
To configure the plant processes, Simatic PCS 7 has a central engineering system that is equipped with coordinated tools. These are called up via the central project manager (Simatic Manager). It can be used to create the application software and set up and parameterize the hardware components and communication. It is the basic application for the entire engineering of the process control system in terms of creating, managing, archiving and documenting a project.
The operator system is used for process management. The operator stations provide terminals with a visualized and predefined user interface, which the operating staff can use to track and control the process operations. Windows- based PCS 7 web servers enable remote monitoring and operation as well as remote diagnosis and maintenance of the system via the Internet or intranet.
Intelligent field devices ( sensors and actuators ) are controlled via the Simatic PDM (Process Device Manager) device manager. This is used for project planning, parameterization, commissioning, diagnosis and service. The core functions of the device manager include a. setting and changing device parameters, comparing project and device data and managing networks and PCs. The use of intrinsically safe and fault- tolerant controllers enables safety-related controls that react to errors and failures of the system and also have a self-monitoring function. In this way, they identify errors in the process as well as their own internal errors and, if necessary, bring the system into a safe state immediately. These controllers are mainly used in manufacturing technology.
The system has supplied libraries with prefabricated function blocks for graphic configuration, measurement, control and regulation of continuous automation functions ( Continuous Function Chart , CFC), for sequence control ( Sequential Function Chart , SFC) and for operation and visualization ( WinCC ). There is also the option of creating your own function blocks.
