# CAPLfunctionIso11783EnableNameManagement

# Iso11783EnableNameManagement

[Valid for](../../../../Shared/FeatureAvailability.md): CANoe DE • CANoe4SW DE

## Function Syntax

```plaintext theme={null}
dword Iso11783EnableNameManagement( dword ecuHandle, dword enable );
dword Iso11783EnableNameManagement( dword ecuHandle, dword enable, dword bitMask );
```

## Description

This function activates the name management of a node. Not until the name management is activated another node can change the device name of this node by sending a name management message.

## Parameters

* **ecuHandle**: ECU handle
* **enable**:
  * 1: activate the name management
  * 0: deactivates the name management
* **bitMask**: Parts of the device name that are allowed to be changed
  * bit 0 (LSB): Arbitrary Address Capable
  * bit 1: Industry Group
  * bit 2: System Instance
  * bit 3: System
  * bit 4: Function
  * bit 5: Function Instance
  * bit 6: ECU Instance
  * bit 7 (MSB): Manufacturer Code

## Return Values

0 or [error code](../CAPLfunctionsISONLErrorCodes.md)

## Example

```plaintext theme={null}
LONG busHandle;
LONG ecuAddress;
LONG ecuHandle;
char deviceName[8]; // device name of the node

busHandle  = Iso11783GetBus( "ISO11783" );
ecuAddress = dbNode.NmStationAddress; // dbNode must be configured in database

Iso11783MakeName(
  deviceName, dbNode.NmIso11783AAC,
  dbNode.NmIso11783IndustryGroup,
  dbNode.NmIso11783SystemInstance,
  dbNode.NmIso11783System,
  dbNode.NmIso11783Function,
  dbNode.NmIso11783FunctionInstance,
  dbNode.NmIso11783ECUInstance,
  dbNode.NmIso11783ManufacturerCode,
  dbNode.NmIso11783IdentityNumber );
ecuHandle = Iso11783CreateECU( busHandle, deviceName );

if (ecuHandle != 0)
{
  /* allow every component to be changed except arbitrary address capable flag */
  Iso11783EnableNameManagement(ecuHandle, 1, 0xFE);
  Iso11783ECUGoOnline( ecuHandle, ecuAddress );
}
