Coexistence of standard and safety programs on one controller possible

One distributed I/O configuration with standard and safety I/O modules

Uniform engineering for standard and safety control component

Use of existing PROFIBUS or PROFINET transmitting medium even for safety communication

Simple expansion of existing PROFIBUS archtictures about PROFINET, p.ex. via IE/PB-Link (SIMATIC NET)

More easily modified, expanded and documented

Implementation of complex safety functions

In contrast to the hardware solution, the software solution can be easily reproduced

Approved, certified solutions can often be used as self-contained blocks

Early fault detection thanks to better diagnostic functions

Easy migration from PROFIBUS to PROFINET
