4 Data Descriptions
4.1 Machine data
36990 $MA_SAFE_ ACT_STOP_OUTPUT[n]: 0...3
MD number Output assignment active STOP
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning This data defines the assignment of the states
"STOP A/B is active", "STOP C is active" and "STOP D is active" to an output terminal or
system variable.
Structure: Refer to coding of output assignment

Corresponds with ... MD 36980: $MA_SAFE_ SVSS_STATUS_OUTPUT
Further references Refer to Chapter 3, "External STOPs"
36992 $MA_SAFE_CROSSCHECK_CYCLE
MD number Displays axial crosswise comparison clock cycle
Default: 0
Change becomes effective after POWER ON:
Data type: DWORD
Meaning Indicates effective axial comparison clock cycle in seconds.
Obtained from INFO_SAFETY_CYCLE_TIME and the number of data to be compared
crosswise.
The axial value displayed depends on the associated drive module, since the length of the
crosswise data comparison lists between Performance-1/Standard-2 and Performance-2
modules is different.
36993 $MA_SAFE_CONFIG_CHANGE_DATE[n]; n=0...4
MD number Date/time of last configuration change of safety-relevant NCK machine data
Default: "Blank"
Change becomes effective after POWER ON:
Data type: STRING
Meaning Display data which logs when safety-relevant NCK machine data are activated. The last
change is logged in the MD with
field index 0. Previous times in fields 1...4.
Special cases, errors
36994 $MA_SAFE_PREV_CONFIG[n]; n=0...4
MD number Save data to verify safety configuration changes
Default: "Blank"
Change becomes effective after POWER ON:
Data type: STRING
Meaning If the safety configuration is changed, safety-relevant configuration data is stored in this
field.
Special cases, errors

SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Min. input value: 0
Protection level (R/W) 7/2
Applies from SW 4.4.18
associated status (on "1" level)
"STOP A/B is active "
"STOP C is active "
"STOP D is active "
"STOP E is active"
Test stop can be detected using SGA "Pulse enable".
"STOP A/B is active" can only be used for "leading brake control" because after the
time specified in MD36956: $MA_SAFE_PULSE_DISABLE_DELAY changeover is
made from STOP B to STOP A.
"STOP A/B is active", "STOP C is active" and "STOP D is active" can be used for the
forced checking procedure of external STOPs.
