Siemens programmable controllers from the SIMATIC S7 series

Siemens programmable logic controllers of the SIMATIC series are the world market leaders for programmable control systems. More than a million SIMATIC PLCs are already working reliably in automation systems around the world, because with the help of these controllers you can automate everything that can be automated in one way or another, be it automatic lines, mountain railways, power plants, industrial enterprises of any complexity, water treatment plants and many others. …

Controllers from the SIMATIC family are robust, reliable and can be optimally adapted to any industry. Structured programming combined with standard function blocks to build software libraries or extend the existing spectrum with more powerful CPU-compatible products. With all this, the system base is preserved.

For 15 years now, systems have certainly been expanding.SIMATIC S7 is a completely renewed innovative platform capable of integrating the latest technologies and creating a future-oriented automation system. This essentially redefines the functionality of PLC technology.

Today, the SIMATIC series is represented by four models:

• SIMATIC S7-1200

• SIMATIC S7-300

• SIMATIC S7-400

• SIMATIC S7-1500

SIMATIC S7-1200

These are basic controllers designed to automate tasks with medium and low levels of complexity. The controllers are modular and completely universal. They are applicable for the construction of simple nodes of local automation or nodes of automated control systems connected with an intensive exchange of communication data via the industrial Ethernet / PROFINET network and via PtP (Point-to-Point) connections. Controllers can work in real time.

Structurally, all controllers of the series are made in plastic boxes, suitable for mounting on a DIN rail or directly on a mounting plate and have a degree of protection IP20. Compared to the previous S7-200 model, the S7-1200 controller is 35% more compact, and the pin configuration is the same as that of the S7-200. It can work in the temperature range from 0 to +50 degrees.

The device can serve from 10 to 284 discrete and from 2 to 51 analog I / O channels. Communication modules (CM), signal modules (SM), signal I / O boards of digital and analog signals (SB), as well as technology modules can be connected to the central processor of the controller. Together with them, a power supply module (PM 1207) and a four-channel Industrial Ethernet switch (CSM 1277) are used.

SIMATIC S7-300

It is a universal programmable controller and is successfully used for the automation of special purpose equipment such as: textile and packaging machinery, electrical equipment, mechanical engineering equipment, technical control manufacturing equipment, as well as in automation systems for water supply systems and ship installations .

SIMATIC S7-400

Positioned as top-of-the-line controllers. Suitable for machine building automation, in the warehouse, in the automotive industry, for technological installations, in systems for measuring various parameters, data collection, as well as in the textile and chemical industries.

SIMATIC S7-1500

It is an innovative programmable controller that can be used where the S-300 and S-400 are used, but provides additional features such as standard control and homogeneous system diagnostics.

TIA PortalV12 software allows you to convert programs from S7-300 / 400, and S7-1200 programs can be transferred directly to S7-1500 without conversion. The first S7-1500 models do not have support for continuous process automation, but can easily be transferred to S7-400 applications for cyclic process automation.
