MD number
$MN_SAFE_MODE_MASK
Safety Integrated modes
840D
Default: 0
Min. input value: 0
Max. input value: 0x0001
Change becomes effective after POWER ON:
Protection level (R/W) 7/2
Unit: -
Data type: DWORD
Applies from SW 5.3
Meaning
Bit 0=0 $A_INSE[1...64]
Default setting "0"
Bit 0=1 $A_INSE[1...64]
Default setting "1"
(Compatibility mode for older PLC SW versions)
These functions are only supported by the NCK in one channel. This data is not included
in the axial MD checksum SAFE_ACT_CHECKSUM.

MD number
$MN_SAFE_DIAGNOSIS_MASK
Safety Integrated diagnostic functions
840D
Default: 1
Min. input value: 0
Max. input value: 0x0001
Change becomes effective after POWER
ON:
Protection level (R/W) 7/2
Unit: -
Data type: DWORD
Applies from SW 5.3
Meaning
Bit 0=0 SGE differences between NCK and 611D digital monitoring channels are not
displayed
Bit 0=1 SGE differences between NCK and 611D digital monitoring channels are
displayed
Differences between the following SGEs are detected (the listed bit numbers refer to the
axial mapping of the SGEs, these correspond to the following VDI-interface assignment:
Bit
0:
SBH/SG de-selection
= DB3<x>.DBX22.0
Bit
1:
SBH de-selection = DB3<x>.DBX22.1
Bit
3:
SG selection, bit 0 = DB3<x>.DBX22.3
Bit
4:
SG selection, bit 1 = DB3<x>.DBX22.4 (from SW 6)
Bit
12:
SE selection
= DB3<x>.DBX23.4
Bit
28:
SG correction, bit 0 = DB3<x>.DBX33.4
Bit
29:
SG correction, bit 1 = DB3<x>.DBX33.5
Bit
30:
SG correction, bit 2 = DB3<x>.DBX33.6
Bit
31:
SG correction, bit 3 = DB3<x>.DBX33.7
<x> is the axis number
The differences are indicated via Alarm 27004.

MD number
$MN_SAFE_SPL_STOP_MODE
Stop response for SPL errors
840D
Default: 3
Min. input value: 3
Max. input value: 4
Change becomes effective after POWER ON:
Protection level (R/W) 2/7
Unit
Data type: BYTE
Applies from SW 6.3
Meaning
Selects the stop response when errors are detected in the crosswise data comparison of
NCK and PLC-SPL
3: Stop
D
4 Stop
E
When the value 4 is entered in this MD (Stop E) without enabling the external Stop E in all
axes with SI function enable signals ($MA_SAFE_FUNCTION_ENABLE not equal to 0)
results in Alarm 27033, "Axis %1 Invalid parameterization of
MD MN_SAFE_SPL_STOP_MODE".
To remedy this, either parameterize Stop D or set bit 4 and bit 6 in
$MA_SAFE_FUNCTION_ENABLE for all of the axes involved.
This machine data is incorporated in the checksum for safety-relevant machine data
($MA_SAFE_ACT_CHECKSUM, $MA_SAFE_DES_CHECKSUM)
If this MD is set to 4, then DBX36.1 in DB18 must also be set to signal the PLC about this
parameterization. For a different parameter assignment, Alarm 27090 is output, "Error for
crosswise data comparison NCK-PLC".
