# Summary

### Summary – Selmo: Model-based machine logic with clarity, safety and documentation

Welcome to the Selmo Knowledge Base. **Selmo** (Sequence Logic Modelling) is an end-to-end standard for modeling, describing and controlling machine processes – not as pure program code, but as **formal behavior model**. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))

#### What is Selmo?

* Machines are described with a fixed structure:\
  Hardware zones (HWZ) → Sequences (SEQ) → Zones (Input, Output, Mem). ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))
* Each Sequence represents a clearly defined logical process step with states, signals, parameters and safety behavior. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))
* From this model the following can be generated automatically:\
  • PLC code (control-relevant code)\
  • HMI display\
  • Diagnostic information\
  • Technical documentation (signal directories, flow diagrams, safety matrices etc.) ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))

#### Why use Selmo?

| Scope of benefits                            | Description                                                                                                                                                                                                                                                                |
| -------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **documentation**                            | Documents such as signal directories, flow charts and safety matrices are **generated automatically** and remain synchronized with the model. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))                                                       |
| **Functional safety & standards compliance** | States, operating modes, reset logic and safety reactions are modeled deterministically and are verifiable. The model meets requirements from standards such as ISO 12100, IEC 62061 and ISO 13849. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/)) |
| **Project structure & transparency**         | Each Sequence forms a validatable, self-contained process step – which facilitates traceability, modularity and clearly defined handovers. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))                                                          |
| **Integration & tools**                      | Selmo provides checklists, templates, export formats (e.g. CSV, IEC code, HMI data), change logs and a knowledge base with standards references. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))                                                    |

#### Conclusion

Selmo is more than technology – it is an **integrated, formal system model**, which connects control logic with documentation and regulatory requirements. It creates clarity, increases safety and enables trust – for developers, operators and auditors alike. ([selmotech.gitbook.io](https://selmotech.gitbook.io/selmo-solution/))

# 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://infosys.selmotech.com/selmo-solution/selmo-solution-en/summary.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.
