SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
Mode group not ready
Channel not ready
NC start disable in this channel
Interface signals are set
Alarm display
NC stop for alarm
Correct the MD
Switch control system OFF and ON again.
PROFIsafe: Number of NCK F modules (%1) <> number of S7
modules (%2)
F
%1 = number of parameterized NCK--F modules
%2 = number of parameterized S7--F modules
The number of F modules parameterized using the NCK machine data
MD10386/10387 $MN_PROFISAFE_IN/OUT_ADDRESS is:
-- greater than the number of PROFIBUS slaves in the configured S7
PROFIBUS
-- less than the number of F modules in the configured S7 PROFIBUS
-- greater than the number of F modules in the configured S7
PROFIBUS
If the specified number of S7 F modules = 0, then none of the F
modules, configured in the S7--PROFIBUS configuration were found.
Generally, the cause of this alarm is an error in the parameterization of
the PROFIsafe master address.

Check the F parameterization in MD10386/10387 $MN_PROFI-
SAFE_IN/OUT_ADDRESS.
Check the F configuration in the S7 PROFIBUS configuration.
Check the parameterized PROFIsafe master address in MD10385
$MN_PROFISAFE_MASTER_ADDRESS and S7 PROFIBUS
configuration.
Switch the control OFF -- ON.
PROFIsafe: NCK F module MD %1[%2] unknown
%1 = MD name
%2 = MD field index
The F module parameterized in the specified machine data is unknown
under this PROFIsafe address in the S7 configuration.
