Figure 7-7 Safe state selection
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
input for checking the switching state for forced dormant error detection
● Status parameters r10052/r10053
