# InOut Zone

Die Zone-InOut vereint eine Input- und Output-Zone. Um den Ausgang anzusteuern, ist es notwendig, den Operanden „S” einzutragen. Dadurch wird der Output der Zone so lange angesteuert, bis der Input der Zone den logischen Wert 1 meldet. Damit ist die Bedingung erfüllt und es kann in den nächsten Schritt weitergeschaltet werden. Soll der Input der Zone überwacht werden, ist dies durch Eintragen des Operanden „I” möglich. Ein Beispiel für die Anwendung der Zone-InOut ist die Steuerung eines Ventils eines Pneumatikzylinders durch den Output der Zone und die Überwachung der Endlage des Zylinders durch den dazugehörigen Input der Zone.

# 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-struktur-und-standard/selmo-technischer-standard-und-struktur/beschreibung-selmo-plc-code/sequence-logic/less-than-sequence_name-greater-than/struktur-less-than-sequence_name-greater-than/sequence-logic-control/zone-call/zonen-methoden-call/inout-zone.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.
