Used F useful data
Fig. 3-51 Assignment example: F useful data to the SPL-SGEs
The following machine data:
• MD 10099: $MN_INFO_PROFISAFE_CYCLE_TIME
• MD 10385: $MN_PROFISAFE_MASTER_ADDRESS
• MD 10386: $MN_PROFISAFE_IN_ADDRESS
• MD 10387: $MN_PROFISAFE_OUT_ADDRESS
• MD 10388: $MN_PROFISAFE_IN_ASSIGN
• MD 10389: $MN_PROFISAFE_OUT_ASSIGN
are calculated into axial checksum machine data:
• MD 36889: $MA_SAFE_ACT_CHECKSUM[n] (actual checksum).
Changes only become active after they have been acknowledged on an
axis-for-axis basis:
SINUMERIK HMI Advanced or HMI Embedded:
Operating area changeover > Startup > Drive Configuration > Soft key
"Confirm SI data"
If changes to the machine data are not acknowledged, an alarm is issued the
next time that the NCK runs up:
• Alarm: 27032 "Axis [Name] Checksum error safe monitoring".
Acknowledgement and an acceptance test are required!
Furthermore, the following error states are also detected and the appropriate
alarms displayed:
