# Iso11783AppRxIndication (Callback)

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

## Function Syntax

```
dword Iso11783AppRxIndication( long ecuHandle, long srcAddr, long dstAddr, long length, long pgnum );
```

## Description

The callback function indicates to the user that a parameter group has been received. It is not possible in CAPL to receive PG data through a callback function. For this reason, the data must be explicitly requested within the callback function with [Iso11783GetRxData()](CAPLfunctionIso11783GetRxData.md).

It should be noted that this function is only called once for each logical ECU within a node when global PGs are received.

## Parameters

* **ecuHandle**: ECU handle
* **srcAddr**: Source address
* **dstAddr**: Destination address
* **length**: Number of received data
* **pgnum**: PGN of the received parameter group

## Return Values

—

## Example

```c theme={null}
dword Iso11783AppRxIndication( LONG ecuHdl, LONG srcAddr, LONG dstAddr, LONG len, LONG pgNumber)
{
  char data[50];
  Iso11783GetRxData( elCount(data), data );
  /* user code */
  return 0;
}
```
