Distributed Configuration of S7 Distributed Safety and PROFINET IO
The following are required to set up PROFINET IO:
•
One CPU 31xF-2 PN/DP or CPU 416F-2 (as of firmware version V 4.1) with CP 443-1
Advanced
•
One PROFINET IO line
•
Fail-safe I/O for PROFINET IO, for example:
–
One ET 200pro with:
IM 154-4 PN HIGH FEATURE
Fail-safe modules and ET 200pro standard modules, if necessary
–
One ET 200S with:
IM 151-3 PN HIGH FEATURE
Fail-safe modules and ET 200S standard modules, if necessary
•
Fail-safe I/O standard devices
•
Components for configuring PROFINET
–
Passive network components (cables, plugs)
–
Active network components (switches, routers, etc.) if necessary
