The free DRAM memory is displayed in machine data
S
MD18050: 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:
S
MD18050: 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 NCK
start-up!
