# Standaard - FLOAT

De bronnamen geven de natuurlijke eenheid van de waarde aan. De `scale` bepaalt hoe deze waarde naar het register wordt omgerekend. Bijvoorbeeld:

* `power_delivered_kw` met `scale 1000` wordt als `W` weggeschreven
* `voltage_l1_v` met `scale 1` blijft `V`
* `gas_delivered_m3` met `scale 1` blijft `m3`

Let op:

* `signed_current_l1_a`, `signed_current_l2_a` en `signed_current_l3_a` kunnen negatief zijn bij teruglevering
* `net_power_total_kw` en `net_power_l1_kw` t/m `net_power_l3_kw` kunnen positief of negatief zijn
* `MBUS_VAL_UNAVAILABLE` is `0xFFFFFFFF`

Onderstaande kan benaderd worden via FC03 en FC04.

52\* P1 Status is offline als:

* er geen p1 data is ingelezen
* er drie opeenvolgende berichten een error geven
* er langer dan 3 seconden (smr5) of 30 seconden(smr2 en 4) geen data is ontvangen

Overige notes

* p1\_device\_id is een vaste uint32 identificatie -> ascii value 0x5031444F = P1DO
* firmware\_version\_packed is technisch bedoeld voor softwarematige interpretatie, niet als leesbare float -> MMmmpp ⇒ 4.15.9 = 0x00040F09

## Geen waarde aanwezig

Float: NAN

UINT32: 0xFFFFFFFF

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.smart-stuff.nl/dsmr-api/koppelingen/modbus-rtu-tcp/standaard-float.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
