11.9 Control via TM54F
The actuator connected to the F-DO can also be tested under specific conditions as part of
forced checking procedure (test stop). See Chapter "Forced checking procedure or test of the
switch-off signal paths (test stop) for Safety Integrated Basic (Page 640)".

F-DO signal sources
A drive group contains several drives with similar characteristics. The groups are
parameterized at the p10010 and p10011 parameters.
The following signals are available for interconnecting (p10042, ..., p10045) each one of the
four drive groups with the F-DO:
● STO active
● SS2 active
● SLS active
● Safe State
● Active SLS level bit 0
● SDI positive active
● SLP active
● Internal event
The following safe state signals can be requested via p10039[0...3] for each drive group (index
0 corresponds to drive group 1 etc.):
● STO active (power removed/pulse deleted) ● SS1 active
● SS2 active
● SLS active
● SDI positive active
Figure 11-7
The same signals (high-active) of each drive or drive group are logically linked by means of
AND operation. The different signals selected via p10039 are logically OR'ed. Result of these
