WARNING
You may only access the addresses occupied by useful data. The other address ranges
occupied by the F-modules are assigned for functions including safety-related
communication between the F-modules and F-CPU in accordance with PROFIsafe.
With the 1oo2 evaluation of sensors, only the less significant channel of the channels that
are grouped as a result of the 1oo2 sensor evaluation can be accessed in the safety
program.
Additional Information
Detailed information about fail-safe I/O access can be found in the
S7 Distributed Safety,
Configuring and Programming
manual or the
S7 F/FH Systems, Configuring and
Programming
manual.
