## Function Syntax

```
long SCC_StartPassive ( )
```

```
long SCC_StartPassive ( dword SLACMode )
```

## Description

This function activates the modeling library, but does not start an SCC simulation (i.e. a state machine). In this state, callbacks can be received, and test functions can be called.

## Parameters

* **SLACMode**: Controls the behavior regarding SLAC, which overrides the parameter `<UseSLAC>` from the XML configuration:
  * 0 = SLAC is skipped (may be done manually)
  * 1 = SLAC is used
  * 2 = EV: use SLAC depending on link status (not recommended due to HomePlug Green PHY chip instabilities)

## Return Values

* **0**: Not successful
* **1**: Successful

## Example
