Wallbox - P1MB

Firmware v2 register overview for the Wallbox - P1MB mapping.

Mapping behaviour

• Device Manager mapping value: 12

• Profile: XEMEX

• Read function codes: FC03 and FC04

• Register widths: mixed 16-bit and 32-bit

• 32-bit word order: high word first (MSW-LSW)

• Unmapped register handling: Zero-filled

Device ID, baud rate and serial format are global firmware v2 settings. They are not changed when this mapping is selected.

Reading the table

• Words is the number of consecutive 16-bit Modbus registers occupied by the entry.

• Source names correspond directly to the firmware v2 recipe source.

• Conversion records the exact scale, transform or direction handling configured by the recipe.

• This page is generated from mb_recipe.h and modbus_profiles.h for firmware 2.3.0.
