SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MN_INFO_SAFETY_CYCLE_TIME
Display, monitoring clock cycle time
Min. input limit: –
Protection level: 7/0
Display data: Displays the actually effective monitoring clock cycle. This data cannot be
written to.
The data value is always re–calculated as soon as one of the following data is changed:
SAFETY_SYSCLOCK_TIME_RA TIO
POSCTRL_SYSCLOCK_TIME_RA TIO
SYSCLOCK_CYCLE_TIME
The new value only becomes effective after Power On.
MD 10090: $MN_SAFETY_SYSCLOCK_TIME_RATIO
/FBSI/ see Chapter 5.1, "Monitoring clock cycle", Chapter 5.2 "Crosswise data comparison"
$MN_INFO_CROSSCHECK_CYCLE_TIME
Displays the clock cycle time for a crosswise data comparison
Min. input limit: –
Protection level: 7/0
Display data: Maximum crosswise data comparison in seconds.
This is obtained from the INFO_SAFETY_CYCLE_TIME and the number of data to be
compared crosswise (depending on the drive type being used, this can differ for the individ-
ual axes).
The data value is always re–calculated as soon as one of the following data is changed:
SAFETY_SYSCLOCK_TIME_RA TIO
POSCTRL_SYSCLOCK_TIME_RA TIO
SYSCLOCK_CYCLE_TIME
The new value only becomes effective after power on.
MD 10090: $MN_SAFETY_SYSCLOCK_TIME_RATIO
MD 36992: $MA_SAFE_CROSSCHECK_CYCLE
/FBSI/ see Chapter 5.1, "Monitoring clock cycle", Chapter 5.2 "Crosswise data comparison"
$MN_INFO_NUM_SAFE_FILE_ACCESS
Number of SPL file access operations
Min. input limit: –
Protection level: 0/0
Display data: SPL file /_N_CST_DIR/_N_SAFE_SPF has been accessed n–times in the
protected state. This MD is only used for service purposes. The value of the MD can only
be 0 or 1. The value cannot be changed.
