# Default - TeltoCharge

## Mapping behaviour

* Device Manager mapping value: `0`
* Profile: `P1M`
* Read function codes: `FC03` and `FC04`
* Register widths: 32-bit entries unless a text/fill range is shown
* 32-bit word order: high word first (MSW-LSW)
* Unmapped register handling: Modbus exception

{% hint style="info" %}
Device ID, baud rate and serial format are global firmware v2 settings. They are not changed when this mapping is selected.
{% endhint %}

## 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.
