11.4.1
DRAM memory
Free memory
The free DRAM memory is displayed via the following machine data:
●
MD18050 $MN_INFO_FREE_MEM_DYNAMIC (free dynamic memory)
The free DRAM should not be less than 15,000 bytes.
CAUTION
Before you enlarge DRAM areas, you should first check whether the free memory is
sufficient:
•
MD18050 $MN_INFO_FREE_MEM_DYNAMIC (free dynamic memory)
If more dynamic memory is requested than is available, the SRAM and therefore all user
data will be cleared without prior warning on the next NC startup!
To avoid data loss, a series startup file should be created before reconfiguration (see
Section "Creating a Series Startup File" (Page 543)).
