Firmware v2 register mappings

Complete firmware v2 mapping and register reference.

Firmware v2 contains all selectable mapping profiles in one firmware image. Selecting a mapping changes only the exposed register model. It does not change the Modbus device ID, baud rate or serial format.

Global communication settings

The factory defaults are device ID 43, 38400 baud and 8E1. These are global settings and can be changed independently in the Device Manager.

Both FC03 and FC04 read the active mapping. The preferred configuration method is the Device Manager. Firmware v2 also accepts these global FC06 writes:

Address	Setting	Values
0	Device ID	1-254
2	Serial format offset	46-91
4	Baud-rate index	0-4 = 9600, 19200, 38400, 57600, 115200
8	Mapping	Mapping value from the table below

Charge Pro and DRIS are selectable in firmware 2.3.0, but no register recipes are assigned to their profiles. See their pages for details.

Register table conventions

Each mapping page is generated from the active firmware v2 recipe and profile definitions. Addresses are shown in decimal and hexadecimal. A 32-bit value occupies two consecutive 16-bit Modbus registers.
