5.2 wM-Bus Configuration

In the Customer tab (see the following figure), the ATA8510 configuration tool reserves some bytes for the M-field and A-field that are transmitted in the first block of the RF telegram according to the EN13757-4:2005 standard. For more details, refer to the EN13757-4:2005 Standard.

Figure 5-4. Customer Tab – Customer Settings

As the A-field must be unique for each device, these two values can be set via EEPROM write.

Table 5-2. wM-Bus Configuration
Field	EEPROM Address	Register Name
M-field	0x0280	wmbus_man_id_0 (low byte)
M-field	0x0281	wmbus_man_id_1 (high byte)
A-field	0x0282	wmbus_addr_0 (low byte)
	0x0283	wmbus_addr_1
	0x0284	wmbus_addr_2
	0x0285	wmbus_addr_3
	0x0286	wmbus_addr_4
	0x0287	wmbus_addr_5 (high byte)
