1.1 Introduction
Overview
PROFIsafe enables safe communication by detecting and reporting all communication
errors. Data security is continuously monitored on the PROFIBUS in the process.
1.2 Technical advantages of PROFIsafe
The main advantage of PROFIsafe is that the PROFIBUS communication channel becomes
secured by a protocol in a transparent way. Thus incorrect values cannot be transferred to
the master without being discovered. The user does not need any special network
components. All the user needs is the standard network components of PROFIBUS.
However, the CPU must be suitable for safety applications.
In the following example, you see that PROFIsafe and PROFIBUS devices can be operated
simultaneously on a PROFIBUS network.
