| These failsafe controllers are based on timeproven standard
PLCs. The PROFIsafe profile has been added to both PROFIBUS and PROFINET
for safety-related communication. Safety-related and standard
communication are now possible over only one standard bus cable. With
PROFINET, safety-related communication is also ensured in wireless
networks. The engineering for safety functions and standard functions
is carried out with the same engineering tools (STEP 7) - supported by
off-the-shelf FBs with certification from the German Technical
Inspectorate (TÜV).
