Index 1 = Size of the volatile Siemens cycle program memory; the data may be written,
but will overwritten during the runup by the value requested by the Siemens cycles.
Index 2 = Size of the non-volatile memory for system files in the SRAM. E.g. storage
location of the NRK fault file.

Description: A FIFO buffer is needed on the NCK for each program level (main program or subprogram)
that is processed externally (reload mode).
The size of the FIFO buffer is defined in kbyte by MD18360 $MN_MM_EXT_PROG_BUFFER_SIZE.
MD18360 $MN_MM_EXT_PROG_NUM sets the number of FIFO buffers which are simultaneously
available.
During startup, the memory size determined by multiplying MD18360
$MN_MM_EXT_PROG_BUFFER_SIZE by MD18362 $MN_MM_EXT_PROG_NUM is reserved in the DRAM.
If the stated value exceeds the available memory space, alarm 4077 is output when
writing the machine data.

Description: Number of program levels that can simultaneously be in "Processing from external
source" mode NCK-wide.
System resources are reserved for the HMI <-> NCK communication during "Processing
from external source". Machine data MD18362$MN_EXT_PROG_NUM defines the number of
possible program levels.
The memory space is reserved during power on by MD18360 $MN_MM_EXT_PROG_BUFFER_SIZE *
MD18362 $MN_MM_EXT_PROG_NUM. If it is found during program execution that all system
resources are occupied, this is reported by alarm 14600.
