SIEMENS SIMATIC S7-200

Programmable Controllers SIMATIC S7-200 are designed to build a relatively simple control systems, other than minimal costs for the purchase of equipment and system development.
The controllers can operate in real time and can be used to build the units of local automation and nodes that support intensive data communication exchange through networks of Industrial Ethernet, PROFIBUS-DP, AS-Interface, MPI, PPI,
MODBUS, telemetry systems, and modems.
Features:
• Compact plastic casing with protection degree IP20.
• Easy connection of external circuits via terminal blocks with screw terminals. Protection of live parts opening with plastic caps.
• A full-time or optional removable terminal blocks that perform module replacement without removing their external circuits.
• Mounting on standard 35mm rail or on a flat surface with mounting screws.
• Connect modules with flat cables, mounted in each expansion module.
For programming and configuration of the S7-200 uses the package STEP 7 MicroWin

SIEMENS SIMATIC S7-300

Versatile modular programmable controller to automate the tasks of low and medium level of complexity.
A wide range of modules for maximum adaptation to the demands of the problem being solved.
The use of local and distributed input output structure and the inclusion of a simple network configuration.
Comfortable design and work with natural cooling.
Free building features when upgrading the control system.
High performance due to the large number of built-in functions.
The design features
Programmable Controllers S7-300 can be composed of:
• CPU module (CPU). Depending on the degree of complexity of tasks in the programmable controller solution can be used by more than 20 types of CPUs.
• Power supply (PS) for the controller's power supply by AC or DC.
• Signal modules (SM), designed for input and output of digital and analog signals, including the FailSafe and fashion whether with integrated Ex-barriers. Supports Patriotic nye Standard calibration of resistance thermometers and thermocouples.
• Communications processor (CP) - intelligent fashion is operating stand-alone processing and communication tasks in industrial networks AS-Interface, PROFIBUS, Industrial Ethernet, PROFINET and PtP communication systems. The use of additional software allows you to expand communications capabilities of the controller supports data exchange networks, MODBUS RTU, MODBUS / TCP, BACnet and KNX EIB. To operate in remote control systems S7-300 can be supplemented with the hardware and software SINAUT ST7 and SIPLUS RIC.
• Function modules (FM) - intelligent modules are equipped with built-in microprocessor and capable of performing the task of automatic control, weighing, positive tsionirovaniya, high-speed counting, motion control, etc.
For programming and configuration of the S7-300 uses the package STEP 7

SIEMENS SIMATIC S7-400

Modular programmable controller to solve the complex problems of automatic control.
• Wide range of modules for maximum adaptation to the demands of the problem being solved.
• The use of distributed input-output structures and the inclusion of a simple network configuration.
• "Hot" swappable.
• Comfortable design and work with natural cooling.
• Free building features when upgrading the control system.
• High performance thanks to the large number of built-in functions.
The design features
Programmable Controllers S7-400 can be composed of:
• CPU module (CPU). Depending on the complexity of tasks in the programmable controller can be used by different types of CPUs. If necessary use a multiprocessor configuration,
including up to four CPUs.
• Signal modules (SM), designed for input and output of digital and analog signals.
• Communications processor (CP) for the organization of network data via Industrial Ethernet, PROFINET, PROFIBUS or PtP interface.
• Function modules (FM) - intelligent modules to meet the challenges of high-speed counting, positioning, automatic control, and others.
• Interface Modules (IM) for connecting expansion racks to the base unit controller
• Power supply (PS) for the controller's power supply by AC or DC.
Programmable Controllers S7-400 can be equipped with different types of CPUs, which differ in computing power, memory size, speed, number of built-in interfaces, etc.
For programming and configuration of the S7-400 uses the package STEP 7

* programming is possible with appropriate software and hardware
