# 🧭 Proposal: Content structure for the Selmo Studio user manual

#### **0. Introduction**

* What is the Selmo Studio?
* Purpose of the user manual
* Target groups: modelers, commissioning engineers, planners

***

#### **1. Basics and user interface**

* Structure of the studio (main areas: project structure, layers, zones, HMI)
* Navigation, icons, operating concepts
* Terms: Plant, HWZ, SEQ, Zone, Parameter, Bit-Control

***

#### **2. Create project structure**

* Create new project
* Creation of Plant, HWZ, SEQ
* Naming, structural conventions
* Versioning and metadata

***

#### **3. Zone management**

* Add zone (Input / Output / In-Out / Mem)
* Signal linking (symbol name, IO address, HMI text)
* MXIC assignment (button + condition)
* CMZ assignment (safety monitoring)
* Activate pair-check and bear-check

***

#### **4. Process modeling – Logic Layer**

* Create states: `State`, `Timer`, `Decision`, `Jump`, `Repeater`, `Sequence cross`
* Define transitions
* Label states (for HMI)
* Set start and end state

***

#### **5. Bit-Control – System Layer**

* Set operands: `0`, `S`, `i`
* Validity per state and zone
* Check interlock zones
* Detect dependencies

***

#### **6. Parameter Layer**

* Add parameters: `IN`, `OUT`, `IN/OUT`
* Description, unit, value ranges
* Usage in the model
* Export format / OPC UA mapping

***

#### **7. Safety functions**

* CMZ at SEQ, HWZ, PLANT level
* Configure MXIC matrix
* Restart conditions (reset logic, EOC mode)
* Test paths, fault triggers

***

#### **8. Validation and simulation**

* Model checking: structure & logic
* Test functions: HMI preview, process analysis
* Enter or teach step time
* Simulation vs. real IO

***

#### **9. Export and code generation**

* IEC 61131-3 project structure
* Export: PLC code, GVLs, POUs
* HMI export (visualization)
* CSV files: IO mapping, CMZ, MXIC, parameters
* Change history / revision documentation

***

#### **10. Project maintenance and versioning**

* Duplicate model
* Secure revision
* Change documentation (Model\_ChangeLog)
* Team collaboration (recommendation)

***

#### **11. Application examples (optional)**

* Example: simple tensioning station
* Example: modular machine cell
* Example: OPC UA integration
* Show project structure & export

***

#### **12. Appendix**

* Glossary
* Keyboard shortcuts
* Troubleshooting (common errors)
* Link to Selmo support documentation

# 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/operation-selmo-studio/proposal-content-structure-for-the-selmo-studio-user-manual.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.
