# All step sequences Ready2Start

**All Step Sequence Ready2Start** The following PLC code checks whether all sequences associated with the zone are free of errors and therefore ready to start. A reusable output is assigned for this function and will be used later for the automatic status lamp display.

```
// --------------------------------All Step Sequences Ready2Start--------------------------------

   (*
   The plc code below are used to check if all sequences associated with the zone have no faults and hence are ready to start. 
   A reusable output is allocated for this function. This is used later for the automatic status lamp indicator.

# 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/selmo-structure-and-standard/selmo-technical-standard-and-structure/description-selmo-plc-code/hardware-zone-control/less-than-hwzone_name-greater-than/less-than-hwzone_name-greater-than_control/all-step-sequences-ready2start.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.
