Address range
M0 to M9999
M0 to M999 free; are deleted only after entry of the code number 531210, not
by a reset (non-volatile range). The range can be reduced or enlarged in the
*.CFG file of the PLC compiler.
M1000 to M3999 are free; they are deleted during reset.
M4000 to M5999 reserved for NC/PLC interface
(M4800 to M4999 are deleted before the first run of the PLC program, e.g. after
compilation or restarting).
M6000 to M9999 are free. They are deleted during reset.

B0 to B9999 (8 bits)
B0 to B255 are free; depending on the definition in the *.CFG file of the PLC
compiler, the defined range is deleted only after entering the code number
531210, not during reset (nonvolatile range). If no range is defined in the *.CFG
file, B0 to B127 is the nonvolatile range.
B256 to B2047 reserved for NC/PLC interface.
B2048 to B9999 are free; they are deleted during reset.

Note
1 byte = 8 bits
1 word = 2 bytes = 16 bits
1 double word = 2 words = 4 bytes = 32 bits
