Siemens SINUMERIK 840D sl Function Manual page 381

● If a single output signal is connected to a system variable, the following applies: If MD bit
31 is set, then the signal is processed inverted.
● If several output signals are connected to the same system variable, the following applies:
If MD bit 31 is set, then the relevant signal is initially inverted. The (in some cases inverted)
output signals are then AND'ed, and the result is entered in the system variable.
Note
The maximum input value for all axis-specific NCK_SGA configuring machine data is
84010620.
An incorrect entry will be detected the next time the system boots and flagged using Alarm
27033.

$MA_SAFE_SVSS_STATUS_OUTPUT
Output assignment, SBH/SG active
Min. input limit: -
Assigns the output to signal the status of the functions safely reduced speed and Safe Oper‐
ating Stop.
Structure: Coding of the output assignment
Signal means:
= 0, SG and SBH are not active
= 1, SG or SBH is active
● Input value of 0 means: there is no assignment, the output remains unaffected.
● Input value of 80 00 00 00 means: There is no assignment, the output remains fixed at 1
● If a single output signal is parameterized to a system variable, the following applies: If MD
bit 31 is set, then the signal is processed inverted.
● If several output signals are connected to the same system variable, the following applies:
If MD bit 31 is set, then the relevant signal is initially inverted. The (in some cases inverted)
output signals are then AND'ed and the result is visible in the system variable.
