# Iso11783IL\_TIMConnectSysVarToSynchronizationPoint

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

## Function Syntax

* `long Iso11783IL_TIMConnectSysVarToSynchronizationPoint(dbNode counterpart, char[] sysVarNameWithPath);` // form 1
* `long Iso11783IL_TIMConnectSysVarToSynchronizationPoint(byte counterpartAddress, char[] sysVarNameWithPath);` // form 2
* `long Iso11783IL_TIMConnectSysVarToSynchronizationPoint(dbNode participant, dbNode counterpart, char[] sysVarNameWithPath);` // form 3
* `long Iso11783IL_TIMConnectSysVarToSynchronizationPoint(dbNode participant, byte counterpartAddress, char[] sysVarNameWithPath);` // form 4

## Description

Connects the synchronization point of a TIM client/server connection to a system variable. Possible values of the system variables are:

* 0: Authentication not started
* 1: Authentication started
* 2: Authenticated

To release connection between the system variable, just call the same method again, but with the empty string instead of the name of system variable.

## Parameters

* **counterpart**: TIM counterpart of the client/server connection.
* **counterpartAddress**: Address of the TIM counterpart of the client/server connection. Value range: 0..253
* **sysVarNameWithPath**: Name of the system variable, all namespaces inclusive.
* **participant**: Simulation node (TIM server or TIM client) to apply the function.

## Return Values

* **0**: Property has been set successfully
* **\< 0**: An error has occurred, see [error codes](../../../CAPLfunctionsISOj1939ErrorCodes.md)

## Example

```plaintext theme={null}
Iso11783IL_TIMConnectSysVarToSynchronizationPoint (TIMClient, "Server::SynchPoint");
```
