The following signals can be requested by means of p10039[0...3] for each drive group
(index 0 corresponds with drive group 1 etc.):
● STO active (power removed)
● SS1 active
● SS2 active
● SOS active
● SLS active
Figure 7-7
The same signals (high-active) of each drive or drive group are logically linked by means of
AND operation. The different signals selected through p10039 are logically linked by means
of OR operation. Result of these logic operations is the "Safe State" for each drive group.
Each F-DO supports the interconnection of up to 6 signals by way of indexing (p10042[0...5]
to p10045[0...5]) and their output as logical AND operation.
F-DO features
● Each F-DO with fail-safe configuration consisting of two digital outputs plus one digital
● Status parameters r10052/r10053
Function diagrams
● 2853 TM54F (F-DO 0 ... F-DO 3, DI 20 ... DI 23)
● 2856 TM54F Safe State selection
● 2857 TM54F assignment (F-DO 0 ... F-DO 3)
