With the PROFIsafe profile, safety communication is seamlessly integrated into PROFIBUS and PROFINET. You do not need to configure a separate safety bus for your safety-related applications. The PROFIsafe profile is implemented as an additional software layer within the devices/ systems, without modifying the standard PROFIBUS communication mechanisms. Thus the standard components (e.g. communications modules, connectors or cables) involved in the communication between the PROFIsafe stations can be used without modification.

PROFIBUS PA and PROFINETĀ is also incorporated with the PROFIsafe profile into "Safety Integrated for Process Automation". This comprehensive range of products and services from Siemens for safe, fault-tolerant applications in the process industry offers you attractive and cost-effective alternatives to separate safety systems.
