Highly available operation without any weak links

Supplier: Siemens Ltd.

Process automation, with its complex sequences, cannot afford to have any weak links in the chain. Downtime and faults may have devastating effects – for people, plants and the environment. To minimize risks, you need to have reliable safety technology for your processes that meets the most stringent demands: the Safety Instrumented System(SIS) of your choice should be reliable, flexible and easy.


The answer is now within reach – the ability to protect personnel, equipment and environment against potential safety hazards. Siemens automation solutions offer the complete Safety Integrated safety concept, which can be seamlessy integrated in standard automation and offer a one-stop range of Siemens products to cover all requirements.

Maximum system availability

SIMATIC Safety Integrated offers systems with both single and redundant design. Redundant systems provide you with maximum availability for your equipment and plants right from the start. Our safety systems ensure minimum unplanned downtimes during operation and, accordingly, lower life cycle costs. The safety-certified modules are completely redundant internally, feature a diverse design and can diagnose internal and external faults quickly
and effectively.

More flexibility

The modular design of SIMATIC Safety Integrated provides a high degree of flexibility allowing for future modifications and expansions. Depending on your requirements, the distributed I/O modules can be equipped or expanded to include standard and safety I/O modules and can be combined in the same station or separately. The system can be configured for SIL 2, SIL 3 or a combination of SIL 2 and SIL 3. This flexibility provides cost savings for applications with a combination of SIL requirements.

Saves costs, space and installation overhead

With SIMATIC Safety Integrated, you benefit from considerable savings potential – in different ways. Thanks to the coexistence of standard and safety I/O modules in one system, you can cut down the number of hardware omponents, save separate wiring and reduce cabinet space. That saves the amount of spare parts you need to have on hand. Since you can use the proven ROFIBUS standard for safe communication by utilizing the certified PROFIsafe profile, you no longer need a separate safety bus.

Greatly simplified engineering

SIMATIC Safety Integrated makes engineering much easier. You benefit from engineering tools, system diagnostics and operator interfaces. You can configure your safety functions for the SIMATIC S7-400FH using our intuitive function block programming tool Continuous Function Chart (CFC) or the SIMATIC Safety Matrix for even more benefits. This easy-to-use configuration tool automatically generates complex safety programs based on a cause & effects matrix, where the cause and effects are easy to link. That means you can configure your safety logic much faster than before.
