SIMATIC Controllers

Siemens offers the right controller for a wide range of automation requirements. The SIMATIC range of controllers comprises of Basic, Advanced, Distributed, Software and Motion Controllers offering impressive scalability and integration of their functions. The engineering in the Totally Integrated Automation Portal (TIA Portal) enables optimum automation solutions to be found for every application.

Software Controllers

Basic Controllers are the intelligent choice for compact automation solutions with integrated communication and technology functions. They are available in both standard and safety versions.

 SIMATIC S7-1200

Advanced Controllers automate not just complete production plants but also applications that demand the greatest performance, flexibility, and networking capability. SIMATIC S7-1500 is the latest controller generation and therefore the most future-proof controller with optimal system performance.

 SIMATIC S7-1500

Distributed Controllers are used for machines with a distributed architecture and for series machines with limited space available. They combine the advantages of a SIMATIC S7-1500 with the design of a SIMATIC ET 200SP. With SIMATIC ET 200pro, a CPU module with S7-1500 technology is available as a modular space-saving solution for tough environmental conditions near the machine.

 Distributed Controllers

The Software Controllers are used wherever maximum precision and speed are required as well as PC-based automation. The PC-based controllers operate independently of the operating system.

Failsafe CPUs for standard and safety applications

Failsafe CPUs are designed to meet the requirements for both standard and failsafe applications in stand-alone machines and plant wide automation. This basic automation controller leverages Integrated Safety applications with local Failsafe IO as well as connectivity to safety rated field devices via PROFIsafe over PROFINET. STEP 7 Safety Basic permits users to create their functional safety programs in the same engineering environment as their standard programs.  This allows users to develop applications much faster because of the interoperability of the software components in the TIA Portal architecture.

Why SIMATIC Controllers?

  • Cost-effective controllers for all performance levels ranging from simple to complex applications

  • Scalable offering ensures portability of programs throughout the full range of controllers

  • Integrated Safety: Cat 4, SIL 3, PLe safety levels available in each size of the Siemens automation controllers

  • Integrated Security: Protection against unauthorized access and intellectual properties

  • Integrated Diagnostics: “No programming” diagnostics automatically displayed on all system devices: HMI, controller web server, engineering software and S7-1500 series display

  • Commissioning features: Integrated Trace within the controller for fault analysis

  • Built-in Communications: Ethernet TCP/IP (onboard all S7-1200/1500 series) for PROFINET IO communications, programming and third-party fieldbus protocols. PROFIBUS is included (either onboard or added module).

  • Connections to existing controllers: Options including native PROFINET, PROFIBUS, Modbus, Modbus TCP, TCP/IP and Open Ethernet protocols. Ability to share data via EtherNet/IP without any code modifications to current installed controllers.
