SIMATIC ET 200SP and ET 200pro Fail-safe CPUs

Controller solution for series machines with limited space and machines with distributed architecture offering safety functions.

Thanks to their compact design, Distributed Controllers are particularly suitable for series machine manufacturing. The integrated safety function makes the system particularly compact, since the absence of the safety controller that would otherwise be required saves space in the control cabinet. They can be accommodated in small control boxes directly on the machine.


In networked plants, connection to a production line’s central control cabinet is realized via PROFINET.

Fail-safe CPUs - CPU 1510SP F-1 PN and CPU 1512SP F-1 PN


The fail-safe ET 200SP CPUs enable standard and safety program processing. They are certified to EN 61508 (2nd Edition) for Functional Safety and are suitable for use in safety-related applications up to SIL 3 according to IEC 62061 and PL e according to ISO 13849.

The 151xSP F CPUs can be expanded with ET 200SP standard and fail-safe modules as well as decentrally via PROFINET / PROFIsafe with any ET 200 systems.

For IT security, additional password protection has been set up for F configuration and F program. The CPUs can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device) in discrete manufacturing technology. The integrated PROFINET IO IRT interface is designed as a 3-port switch so that a line structure can be established in the plant via ports 1 and 2 and also a PG / PC or HMI device can be connected via port 3. 

Fail-safe CPUs - CPU 1513pro F-2 PN and CPU 1516pro F-2 PN

The fail-safe CPUs are the right choice for safety related applications that also contain distributed automation structures alongside central I/O and require protection level IP 65/67.

They can be used as a PROFINET IO Controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 3-port switch so that a linear topology can be set up in the system.

The additional integrated PROFINET IO RT interface with separate IP address can be used, for example, for network separation to operate additional PROFINET IO devices.

In addition, the fail-safe CPUs offers comprehensive control functionalities as well as the ability to connect drives via standardized PLC-open blocks.

The ET 200pro system can be used for controlling autonomous technological functional units, e.g.:

  • Conveyor systems, switches
  • Lifting stations
  • Positioning tasks
  • Workstations in the powertrain segment of the automotive industry

The fail-safe CPU's potential applications are therefore extended manufacturing cells with preprocessing, whereby stand-alone operation is also an option. Cabinet-free installations are possible due to the high IP67 degree of protection.

PC-based distributed controller solution for fail-safe applications.

The SIMATIC ET 200SP Open Controller with fail-safe functionality is a PC-based controller in the design of the ET 200SP I/O system. Here, the pre-installed S7-1500 software controller is used as fail-safe version with Safety Integrated. The integrated safety function makes the system very compact and saves space in the control cabinet because the additional safety controller that is usually required is not necessary here. Its compact design and modular expansion option make this controller particularly well suited for series production of machinery.

 

The ET 200SP Open Controller is also available as a fail-safe Technology CPU using the S7-1500 T/F Software Controller.

Open Controller solution for standard automation tasks with safety-related functions

The fail-safe ET 200SP Open Controller is supplied with a pre-installed fail-safe S7-1500 Software Controller (F-CPU) or as a complete system with software controller and HMI software. The operating system is Windows 10 IoT Enterprise 64 bit.

Open Controller solution for Motion Control tasks with safety-related functions

Traditional motion control functions, such as absolute gearing and camming, are  joined by kinematics control with up to four interpolating axes as required, for example, for pick-and-place tasks. The system offers predefined kinematics, such as cartesian portals, roller pickers, SCARA robots, and delta pickers. A free transformation interface allows seamless integration into the user’s kinematics.
Users parameterize the kinematics with a graphically supported and intuitively operable configuration editor, and program the movements in space in the usual SIMATIC STEP 7 programming environment via standardized function modules in accordance with PLCopen.

The Software Controller with Safety Integrated for machines that benefit from the advantages of a PC-based solution

The CPU1507S F, a software controller with Safety Integrated, enables PC-based automation solutions to run on a SIMATIC IPC with a Windows operating system.

The software controller shows its particular strengths when special automation functions have to be integrated using the programming languages C or C++ or when a close connection of Windows software to the software controller is required.

Because the CPU1507S F can also perform safety-related tasks, there is no need for a second system to take care of these.

Failsafe Software Controller

SIMATIC S7-1500 software controllers as failsafe CPU implement PC-based automation tasks also for safety-oriented control tasks on SIMATIC IPC. The S7-1500 software controller shows its strength, especially when you want to integrate high-level languages into the automation function or when a direct connection to operating-system-based software is required.

Sophisticated fail-safe motion and drive control

The SIMATIC Drive Controller combines what demanding machine concepts need: Motion Control functions of the fail-safe technology CPUs with the versatile SINAMICS S120 drive system – all in one compact controller.

Integrating the fail-safe Technology CPU and the SINAMICS control unit (CU) within the chassis of a SINAMICS CU saves a lot of space in the control cabinet. The strengths of the SIMATIC Drive Controller combined with the SINAMICS S120 multi-axis system come to the fore in systems with three, four, or more axes. The package also includes integrated safety functions, so no separate safety CPU is needed. Like all other SIMATIC products, the engineering takes place in the TIA Portal, saving time on parameterization, which is completed easily in a single environment. The many interfaces and the new “cross-PLC synchronous operation” enable the efficient creation of modular machine designs.
