36980 $MA_SAFE_SVSS_STATUS_OUTPUT
MD number Output assignment, SBH/SG active
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning Assignment of the output for signaling the status of the safely-reduced speed or safe
operating stop function.
Signal means
= 0
(only if STOP C, D or E has not been activated by other functions)
= 1

36981 $MA_SAFE_SS_STATUS_OUTPUT
MD number Output assignment, SBH active
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning This data determines the output or system variable for the "SBH active" signal.
Structure: Refer to coding of output assignment

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Local outputs on the NCU
I/Os on the 611 digital bus
System variable assignment, internal image in the
system memory
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 3.4
SG and SBH are not active
SG or SBH is active
Input value of 0 means:
There is no assignment, the output remains unaffected by status changes
Input value of 80 00 00 00 means:
There is no assignment, the output remains at 1
If a single output signal is connected to a terminal, the following applies:
If MD bit 31 is set, then the signal is processed inverted (ss = 81)
If several output signals are connected to the same terminal, the following applies:
If MD bit 31 is set (ss = 81), the relevant signal is initially inverted. The (in some
cases inverted) output signals are then ANDed and the result output at the terminal.
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 4.2
