# Fault Reset

**Fault Reset Push Button pressed** Pressing any fault reset button within the zone activates the output Fault Reset Button pressed.

Copy

```
// Fault Reset
   {region "Description Fault Reset"}
   (*
   Pressing any reset p/b within the zone activates the reset p/b pressed flag.
   *)
   {endregion}
   aFaultResetMatrix[0] := GVL_<HwZone_name>_IOs.xFaultReset;

   FOR  iIndex := 0 TO 0 DO 
      IF aFaultResetMatrix[iIndex] THEN
         GVL_<HwZone_name>.stHwzIf.xFaultResetPbPressed := TRUE;
         EXIT;
      ELSE
         GVL_<HwZone_name>.stHwzIf.xFaultResetPbPressed := FALSE;
      END_IF
   END_FOR    
```

**Global Fault Reset** The global fault reset output activates the fault reset output for all hardware zones when the fault reset button (Global Utilities) is pressed. By using the global fault reset flag, the fault reset from any zone can be used to reset faults in all zones.

Copy

```
// Global Fault Reset Zone
   {region "Description Global Fault Reset"}
   (*
   The global fault reset sums together all zone reset p/b pressed flags (Global Utilities) and energises the reset output.
   By using the global fault reset flag in this manner, the fault reset from any zone can be used to reset faults in all zones.
   *)

   GVL_<HwZone_name>_IOs.xGlobalFaultReset := GVL_Global.stGlobalIf.xFaultReset;

# 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/fault-reset.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.
