IEC 61508 Safety technology components

Overview of Safety technology components  

Scalable and certified software for safe applications

The safe programming and runtime systems from Phoenix Contact enable manufacturers of safe controllers to develop a complete system according to the requirements of IEC 61508.

The certified software components cover the entire range of safe applications according to IEC 61508 for SIL 2 and SIL 3, from small safety controllers to complex safety-relevant systems.

They create and process native machine code, which is specifically created for the CPU architecture used. This enables you to develop extremely fast safety controllers or even to use very cost-effective microcontrollers.

SAFEPROG programming system (SIL 3)

SAFEPROG function block language  

SAFEPROG function block language (FBL)   

With regard to operation and range of functions, the SAFEPROG safe programming system is specially designed for the requirements of SIL 3 safety technology. Safe programming on the PC is ensured by numerous forward-thinking and fault-detecting measures. Clear identification of safe functions and function blocks as well as non-safe variables increases safety.

SAFEPROG enables you to create your safety application in IEC 61131 with function blocks, ladder diagram or text with Structured Text (ST) as the Limited Variability Language (LVL). This reduces development and certification effort thanks to programming within the context of your sector standard.

SAFEGRID – parameterization of pre-defined safety logic

Parameterization tool for devices with pre-defined safety logic

Safe drives, multifunctional safety relays or safe sensors are typical fields of application for parameterization tasks. Safe parameterization must satisfy the requirements of SIL 3 from the user interface through to the processing of parameters.

The right tool for these applications is SAFEGRID, which is integrated into software applications as a component. The safe parameters can be individually specified via device descriptions in any format.

SAFEGRID is an integral part of our SAFEPROG safe programming system. This guarantees compatibility between the safe, parameterizable devices and the programmable safety controllers at all times.

Plug and Play with certified PLCopen blocks

PLCopen-Safety-certified function blocks for safety technology

The use of standardized and certified safety function blocks considerably simplifies the configuration and certification of a machine or system.

In combination with the safe programming system, Phoenix Contact offers a library with 20 certified function blocks according to PLCopen Safety Specification Part 1 with the additions of Part 3. This contains all important safety functions such as emergency stop, safety door, two-hand control, external device monitoring, and mode selector switch. Extended and additional safety functions can be programmed in user-defined function blocks. Further blocks of the Specification Part 4, Extensions for Presses, are also available.

SAFEOS runtime system (SIL 3)

Universal diverse architecture – the safe technology platform from Phoenix Contact

The SAFEOS safe runtime system is based on a two-channel, diverse, and high-performance architecture. Thanks to manufacturer-independent certification, it can be used for SIL 2 and SIL 3 applications on different CPU architectures, with or without operating system. SAFEOS can be used in the core of a configurable safety relay with very low resource consumption as well as in high-performance safety controllers or robot controllers.

  • The scalability of the SAFEOS runtime system makes it easy to integrate a safe controller.
  • Its highly diverse nature means that one- or two-channel hardware can be used.

SAFEOS Software Development Kit (SIL 3)

Simple development of manufacturer-specific, safe controllers

The fast and simple development of safety-related devices and solutions plays an increasingly important role. What is important is the scalability of the technology components. Possible applications range from the user-friendly parameterization of the safety functionality via small-scale controllers or drives to freely programmable safety controllers for machine building and systems manufacturing and robotics.

Both effort and costs are reduced during the development of safety controllers, devices, and systems thanks to certified software components that can be integrated immediately.

Safety Alliance - open platform for safety technology

Leading safety technology from the Safety Alliance

Leading automation manufacturers, technology and solution providers, experts and service providers for functional safety technology have joined forces for the marketing, further development, and support of an open technology platform.

Phoenix Contact Software technology is at the heart of the Safety Alliance platform. Together we provide an open standard, products, and services for leading safety-relevant solutions.

Device manufacturers and solution providers can thus develop individual products based on standardized, manufacturer-independently certified technology components. This further simplifies the application of functional safety technology.

Certified competence and experience

Phoenix Contact Software has been supplying leading software technology for automation for more than 30 years. We have been developing safety-related software since 2000. Our development process for safe software components has been certified by TÜV Rheinland according to IEC 61508:2010. The certificates from TÜV Rheinland and the Institut für Arbeitsschutz (IFA - Institute for Occupational Health and Safety) can be found on the “Datasheets and certificates” page.
