Commissioning
6.9 Commissioning TM54F by means of STARTER/SCOUT
Not e
A s signment to drive groups
When controlling Safety Integrated functions via a TM54F, you may only assign each drive to
precisely one drive group of the TM54F.
● F-DI discrepancy time (p10002)
The signal states at the two terminals of an F-DI are monitored in order to determine
whether these have assumed the same logical state within the discrepancy time.
Not e
Dis crepancy t ime
The discrepancy time must be set so that it is always shorter than the smallest expected
switching interval of the signal at the F-DIs.
● TM54F sampling time (p10000[0..5])
The Safety sampling time corresponds to the sampling time of TM54F.
Not e
S et ting of t he Safety cycle
The Safety clock (p10000) of the TM54F must be set equal to the monitoring cycle clock of
the assigned drive object:
• r9780 (if Basic Functions are used)
• p9500 (if Extended Functions are used)
● F-DI input filter (p10017)
Parameterizing the debounce time of the F-DIs and single-channel DIs of the TM54F.
The debounce time is rounded off to whole ms and then accepted. The debounce time
specifies the maximum time an interference pulse can be present at F-DIs before being
interpreted as a switching operation.
● F-DI selection
– The Extended Functions enter safety messages in a special message buffer when
– You can also select the terminals for the retraction logic (p10009) required for SLP.

detecting internal errors or violations of limits. These messages must only be
acknowledged in a safety-relevant fashion. You can assign an F-DI terminal pair for
safe acknowledgment (p10006).
