Hardware Address (Mac Id); Memory Map - WAGO 750 Series Manual

3.7 Hardware Address (MAC ID)

Each WAGO Linux fieldbus coupler is provided from the factory with a
unique and internationally unambiguous physical address, also referred to as
MAC ID (Media Access Control Identity). This is located on the rear of the
coupler and on a self-adhesive tear-off label on the coupler side. The address
has a fixed length of 6 bytes (48 bits) and contains the address type, the
manufacturer's ID, and the serial number.

3.8 Memory Map

The memory map in the flash memory looks as follows:
Flash memory address
0x003FFFFF
0x003F0000
0x003EFFFF
0x002D0000
0x002CFFFF
0x00040000
0x0003FFFF
0x00010000
0x0000FFFF
0x00000000
Attention
Do not delete the contents of the BSL/FWL memory addresses.
Otherwise the Linux fieldbus coupler will become inoperative!
Hence, 0x00290000 bytes (approx. 2.69 Mbyte) are available to the file
system. After a successful start of the Linux kernel, the memory map in the
RAM looks as follows:
RAM address
0x00400000
0x00040000
0x0003FFFF
0x00000000
Linux kernel manages the entire free RAM memory.
