Introduction of PROFIsafe into plant automation means a threefold quantum leap:
- From safety-related relay logic to safe programmable logic
- From multi-wire to functional safe serial communication
- From isolated to cooperating safety-related devices
Internationally established technology
PROFIsafe is an integrated safety technology for discrete manufacturing and process automation. The IEC 61508-compliant technology enjoys widespread international acceptance and has been evaluated positively by IFA and TÜV. PROFIsafe has also become an international standard (IEC 61784-3-3).
Efficient use of technology and product
The wide range of products from different manufacturers enables easy, cost-effective system configuration. Training, documentation, and maintenance are required for only a single bus technology, thus saving time and money for system operation.
Simple engineering and installation
Standard and safety-related applications can be programmed for PROFIsafe by means of a single tool and certified function blocks. In addition, the technology enables a high degree of flexibility when replacing existing relay technology and when retrofitting existing installations. The use of certified devices simplifies system acceptance.
Cost savings
Same cost savings as with the introduction of standard PROFI-BUS: reduced wiring, flexible configurations, parameterization, and diagnosis. Easy and cost-efficient system design with a broad product spectrum from all types of manufacturers. Cost saving system acceptance due to certified devices.
Easy implementation of a PROFIsafe solution
A PROFIsafe solution can be easily implemented and inexpensively replicated using TÜV-certified software.
Flexibility based on different architectures
The different architectures of safety-relevant control systems can adapt PROFIsafe communication without difficulty. PROFIsafe thus opens the door to new and innovative device functions.
PROFIsafe is an established technology with significant future potential. PROFIBUS &
PROFINET International (PI) functions as a global network of experts who work cooperatively on further technology development. Investments are protected as a result of this longterm development strategy. All existing and future PROFIBUS standards are used, and will continue to be used, for safety-relevant applications, as well. A simple migration to PROFINET is possible based on the black channel principle (PROFIBUS DP/PROFINET IO).
