$MN_INFO_SAFETY_CYCLE_TIME
Display, monitoring clock cycle time
Min. input limit: 0.0
Display data:
Set monitoring clock cycle in seconds. Is obtained from MD10050 $MN_SYSCLOCK_CY‐
CLE_TIME and MD10090 $MN_SAFETY_SYSCLOCK_TIME_RATIO.
The data value is always re-calculated as soon as one of the following data is changed:
MD10090 $MN_SAFETY_SYSCLOCK_TIME_RATIO
MD10060 $MN_POSCTRL_SYSCLOCK_TIME_RATIO
MD10050 $MN_SYSCLOCK_CYCLE_TIME
The new value only becomes effective after POWER ON.
MD10090 $MN_SAFETY_SYSCLOCK_TIME_RATIO
/FBSIsl/ see Chapter "Monitoring cycle (Page 81)", Chapter "Crosswise data comparison
(CDC) (Page 81)"
$MN_INFO_CROSSCHECK_CYCLE_TIME
Displays the clock cycle time for a crosswise data comparison
Min. input limit: -
Display data:
Maximum crosswise data comparison in seconds.
This is obtained from the MD10091 $MN_INFO_SAFETY_CYCLE_TIME and the number of
data to be compared crosswise (depending on the functionality that has been enabled, this
can differ for the individual axes).
The data value is always re-calculated as soon as one of the following data is changed:
MD10090 $MN_SAFETY_SYSCLOCK_TIME_RATIO
MD10060 $MN_POSCTRL_SYSCLOCK_TIME_RATIO
MD10050 $MN_SYSCLOCK_CYCLE_TIME
The new value only becomes effective after POWER ON.
MD10090 $MN_SAFETY_SYSCLOCK_TIME_RATIO
MD36992 $MA_SAFE_CROSSCHECK_CYCLE
/FBSIsl/ see Chapter "Monitoring cycle (Page 81)", Chapter "Crosswise data comparison
(CDC) (Page 81)"
$MN_INFO_NUM_SAFE_FILE_ACCESS
Number of SPL file access operations
Min. input limit: 0
Protection level: 7/0
Protection level: 7/-
Protection level: 0/0
