For the F-DO, up to 6 signals can be interconnected via indexes (p10042[0...5]); these are
then output AND'ed.
Safe state signal selection
For the CU310-2, the following (Safe State) signals can be requested via p10039[0...3]:
● STO active (power removed/pulses suppressed)
● SS1 active
● SS2 active
● SOS active
● SLS active
● SDI positive active
● SDI negative active
● SLP active
Figure 5-9
The same signals (high-active) are logically AND'ed. The different signals selected via
p10039 are logically OR'ed. Result of these logic operations is the "Safe State". Details can
be found in function block diagram 2876, see SINAMICS S120/S150 List Manual.
