## Selmo System Architecture

Overview of interaction between the Logic Layer (Schaltwerk) and the System Layer (Zonen), centered on the SEQ Engine.

* SEQ Engine
  * Inputs: AR, ¬I, ΣS
  * Output: State\_ID
* State\_ID → Zones
* Feedback → Engine

{% columns %}
{% column %}

### Zones (System Layer)

* IN Zone — Start Button / Sensor
* IN\_OUT Zone — Cylinder / Actuator
* OUT Zone — Lamp / Valve
* MEM Zone — Logic / Parameter
  {% endcolumn %}

{% column %}

### Logic Layer (Schaltwerk)

* SEQ Engine consumes inputs and decides State\_ID
* Logic interprets feedback and updates engine inputs
  {% endcolumn %}
  {% endcolumns %}

## Flow

1. Inputs (AR, ¬I, ΣS) are fed to SEQ Engine
2. SEQ Engine computes State\_ID
3. State\_ID is mapped to one or more Zones (IN, IN\_OUT, OUT, MEM) to perform actions or read state
4. Zones produce Feedback that is returned to the Engine and logic layer, closing the loop

## Compact representation

SEQ Engine (AR, ¬I, ΣS) → State\_ID → Zones (IN / IN\_OUT / OUT / MEM) → Feedback → Engine

## 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://selmotech.gitbook.io/selmo-solution/selmo_architecture_diagram.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.
