Functional capabilities
System has following funсtional capabilities::
- Concerted configuration strategy of all technical tools.
- Unifying bavigation concepts and service of alarm messages.
- Access protection/control with limited operation list, which are permitted to different categories of operating personnel.
- Unifying diagnostic and monitoring system.
- Timing.
- Integation of emergency control systems.
- Complete redundancy of all elements: from devices of field level to the level of operator’s interface.
- Full range of libraries with ready-to-use functional blocks, screen forms and characters.
- Functions of process data import/export from/into CAD/CAE systems.
- Software for package management of manufacturing processs (SIMATIC BATCH, соответствует ISAS88.01).
System is based not only on appliance of the full range of industrial software, but also on appliance of standard components SIMATIC. This allows:
- To carry out selection of automation systems od different productivity depending on the requirements.
- To carry out the step-by-step development of the systems of local and distributed I/O.
- To carry out simple expanding of control and monitoring functions, from simple single-place system to distributed multi-user system with architecture client/server.
- To fulfill expanding of functional capabilities of workstations through the installation of different optional software and hardware components
These special features allow to scale easily the system, to develop optimal decisions, which are maximally adapted to the requirements to control systems of specific industrial enterprises.
Openness of PCS 7 expands on all levels of enterprise management. It is achieved due to standard software interfaces and standard communication interfaces for organization of data exchange with application programs, and tool of export/import of graphics, texts and data.
Control systems
For building of SIMATIC PCS7 V7.1 are used the following models of controllers SIMATIC S7-400:
- AS 414 with data storage capacity of the user’s programs 2,8МB and CPU 414-3/414-3IE.
- AS 416 with data storage capacity 5,6МB with CPU 416-2/11,2MB with CPU 416-3/3IE.
- AS 417 with data storage capacity 30МB.
Besides, to PCS7 can also belong controlers of enhanced reliability (H-systems) and controllers of enhanced security (F-systems or emergency shutdown systems) based on central processing units 412/414/417HF). All the systems include mounting rack, central processing unit, electrical power unit and interface of system bus. They are delivered assembled and before delivery they pass pretesting.
Periphery
Stations of distributed I/OЕТ 200М/S/iSP/pro. Stations are connected to the systems through the bus PROFIBUS-DP. Stations allow to connect and disconnect modules without shut-down of the whole control system and plant. In stations can also used modules with intrinsically safe inputs and outputs (Ex-modules), which meet the requirements of norms EN 50014 and for direct placement in such zone are applied stations iSP and operator panels of guarded construction.
Designing
SIMATIC PCS 7 is equipped with design system ES, which allows to solve many tasks of development of human-computer interface, control systems based on programmable logic controllers, systems of distributed I/O. Design system includes ready technical libraries – standard and APL, equipped with functional testing blocks, powerful edition and replication tools, which greatly raise effectiveness of develoment of the process control systems. Unifying organisation system of data storage and processing allows to use in SIMATIC PCS7 a lot of design tools: STEP 7, SCL, CFC, DocPro, options I&C, technological hierarchy and import/export assistant, WinCC.
Visualization
Workstations of the system SIMATIC PCS7 are developed according to the special requirements to the process control systems. Basic software of working stations is WinCC (Windows Control Center). Main package WinCC is supported by control system options. Control system options assure security of access to the system due to plastic card reader units, timing, displaying of displaying process from videocamera, data archiving, hierarchical process displaying etc. In the system can also be used industrial and office workstations. They can help by creation of simple (with one workstation), and complicated systems “Client-Server” with distributed client structure, up to Web-clients.
OpenPCS 7
Communication station OpenPCS 7 serves for assurance of unified access points from foreign computers to the archival data, current parameters and reports of distribution control systems PCS7. Receiving datas can be analyzed and processed due to standard tools or be used by information system of more high hierarchical level (MIS, MES, ERP). Also is assured both team-work and individual work with PCS7 ОS (CAS, Server, Client, Single Station). Access to the system data (reports, technological parameter values, user data), which are stored on the OS-servers (incl. redundand) or on central archive server PCS7 AS, is carried out through OLE DB, OPC-DA, HDA, AE, HAE.
Networks
Industrial network of the family SIMATIC NET Industrial Ethernet are used for communication providing between engineering systems, control systems and human-computer interface devices. Components of DP/PA connection allow to connect devices of the field level with PROFIBUS-PA interface to PROFIBUS-DP. PROFIBUS-PA is the enhanced version of PROFIBUS-DP, which expands the technology of data transfer to the “smart” equipment. Components of DP/Ffconnecton allow to connect field devices with FOUNDATION Fieldbus H1 interface to PROFIBUS DP. Interface of the sensors and actuators (Actuator Sensor Interface – AS-i) also can be connected to PROFIBUS-DP.
SIMATIC BATCH
SIMATIC PCS7 can also include software package SIMATIC BATCH, which allows to carry out package process control very easy and with minimum costs. SIMATIC PCS7 allows to carry out adaptive management of every processe – both continuos and package-oriented processes. In all ways of programm presentation user have got additional support in creation of recipe control of package processes.
SIMATIC Route Control
Package SIMATIC Route Control provides configuration, control, management and diagnistics tools for SIMATIC PCS7 in order to fulfill tasks in material transport through the pipelines with complex and branched structure. This package fits for every branch with the similar tasks.
PCS7 Asset Management
PCS7 Asset Management equipes SIMATIC PCS7 with tools, which allow to reduce total costs for enterprise maintanance. In the control system Asset Management fulfils functions of control of enterprise equipment, and also all effects concerning diagnistics, support and maintanance of the automation tools.
PCS7 APC
PCS7 is equipped with an integrated library APC, which allows to carry out the upgraded control of technical process. It contains tools for planning of regulation settings, regulation quality control, multidemensional predictive control etc. Interference with external and embedded APC-systems, which realise the whole variety of control optimization methods, is also possible.
