SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
4-233
36979
MD number
$MA_SAFE_STOP_REQUEST_EXT_INPUT
Assignment of input terminals for selecting the "test stop external shutdown"
840D
Default: 0
Min. input value: 0
Max. input value: 0x811E0810
Change becomes effective after RESTART
Protection level (R/W) 7/2
Unit: -
Data type: DWORD
Applies from SW 6.3
Meaning
This MD must be parameterized as soon as the internal pulse cancellation is used (bit 30
in $MA_SAFE_PULSE_ENABLE_OUTPUT=1)
Structure: Refer to coding of input assignment
With each machine data of this kind, a single I/O bit is connected to a terminal or a system
variable. Otherwise, the structure of the machine data is as for 36970 and onwards.
