Simatic S7-200 is a family of programmable logic controllers from Siemens AG from the family of automation devices Simatic S7. Positioned as a micro-PLC for solving simple industrial automation problems [1] . A series of discontinued.
Content
Overview
Simatic S7-200 is a programmable controller designed for building automation systems of low to medium complexity. Key features of the controller:
- ease of installation, programming and maintenance.
- solution of both simple and complex automation tasks.
- possibility of use as autonomous systems or as intelligent slave devices of distributed I / O systems.
- possibility of use in areas where the use of controllers used to be considered economically inexpedient.
- real-time operation and powerful communication capabilities (PPI, MPI ( Multi Point Interface ), Industrial Ethernet , PROFIBUS-DP , AS interface , modem communication).
- compact size, the ability to install in limited quantities.
Scope
Simatic S7-200 microcontrollers are designed to solve control and regulation problems in small automation systems. At the same time, Simatic S7-200 allows you to create both stand-alone control systems and control systems operating in a common information network. The field of application of Simatic S7-200 controllers extends from the simplest automation tasks, for the solution of which simple relays and contactors were used in the past to complex automation tasks [2] . Simatic S7-200 is also used in the creation of such control systems for which in the past, for reasons of economy, it was necessary to develop special electronic modules.
Examples of applications:
- Management of baling presses;
- Cleaning systems;
- Woodworking machine control;
- Automatic gate control;
- Elevator and lift control;
- Conveyor line management;
- Food industry;
- Remote control systems.
- Various dosing systems
Controller Modifications
Controllers are issued in the form of two families:
- Simatic S7-200 : standard programmable controllers for general industrial use.
- Siplus S7-200 : functional analogues of Simatic S7-200 for more severe operating conditions. Operating temperature range from −20 to +70 ° C, higher resistance to vibration and shock loads.
Software for S7-200
The necessary set for performing all the functions of designing control systems (programming, configuring and setting parameters of equipment and communication systems, process control, archiving design data) using SIMATIC S7-200 includes the following software:
- Simatic Step 7-MicroWin ;
- S7-200 PC-Access.
Industrial connection
Simatic S7-200 programmable controllers allow you to use several options for the organization of industrial communications:
- Serial communication via the integrated RS485 port (s) with support for PPI (Point-to-Point Interface), MPI ( Multi Point Interface ) protocols or freely programmable ASCII protocols. In an MPI network, S7-200 controllers are capable of performing only the functions of slave devices. Additional software Instruction Library allows you to use the built-in port (s) of the central processor to support the protocols Modbus RTU and USS .
- Connecting to the AS-Interface network through the CP 243-2 communication processor and performing the functions of a master network device.
- Connecting to the Profibus-DP network via the EM 277 communication module and performing the functions of an intelligent DP slave device.
- Connection to Industrial Ethernet via CP 243-1 communication processor (TCP / IP) or CP 243-1 IT (Web server, e-mail).
- Modem communication using the EM 241 module [3] .
Certificates and approvals
Simatic S7-200 meet the requirements of national and international standards and regulations, including:
- international certificates DIN , UL, CSA, FM, CE.
- maritime certificates LRS, ABS, GL, DNV, BV, NK.
