# Flasher Output

 Der SPS-Code stellt einen Taktausgang zur Verfügung, der in einer beliebigen Sequenz verwendet werden kann. Der Timer-Block (fbFlashOn) gibt an, wie lange der Takt eingeschaltet ist, der zweite (fbFlashOff), wie lange der Takt ausgeschaltet ist. Zusammen wirken sie wie eine Flip-Flop-Schaltung, die einen Ein/Aus-Effekt erzeugt.

   (*
   This PLC code is programmed to provide a Flash Output for use within any sequence.
   The Timer block(fbFlashOn) provides the time for which the Flash Output is ON, the second(fbFlashOff) for the time it is OFF.
   Together they have the effect of a ‘flip - flop’ circuit to create an on / off effect.

   fbFlashOff(IN:= NOT fbFlashOn.Q, PT:= T#1S);
   fbFlashOn(IN:= fbFlashOff.Q, PT:= T#1S , Q=>GVL_Global.stGlobalIf.xFlashOutput);

## 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/plant/global/globalutilities/flasher-output.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.
