Question about writing a STRING to Beckhoff using the ADS driver

[Patrick Boisclair]

Hi all,

I need to write a STRING to a Beckhoff. What would be the way to do it ?
NOTE: Reading works.

I tried this and it fails:

    public static void main( String[] args ) throws PlcConnectionException, 
InterruptedException, ExecutionException
    {
        PlcDriverManager driver = new PlcDriverManager();
        //PlcConnection connection = 
driver.getConnection("eip://10.127.17.10?backplane=1&slot=0");
        PlcConnection connection = 
driver.getConnection("ads:tcp://10.10.11.77?sourceAmsNetId=172.29.48.1.1.1&sourceAmsPort=27&targetAmsNetId=5.62.206.200.1.1&targetAmsPort=851");

        PlcWriteRequest writeRequest = connection.writeRequestBuilder()
                                                 
.addItem("MAIN.Patrick:STRING", "MAIN.Patrick:STRING", "Patrick")
                                                 .build();

         writeRequest.execute().get();
         System.out.println("WRITE DONE" );
    }

Exception in thread "main" java.util.concurrent.ExecutionException:
