36979 $MA_SAFE_STOP_REQUEST_EXT_INPUT
MD number Assignment of input terminals for selecting the "test stop external shutdown"
Default: 0
Change becomes effective after RESTART
Data type: DWORD
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.
Special cases, errors
