Data Subscribe programmatically - Data Change only

[jslate]

Hi

Is it possible to use the DataChanged event of the datasubscriber programmatically?
My code is below.

public MainForm()
        {           
            InitializeComponent();                 
            SubscriptionID = modbusTCPCom1.Subscribe("425000", 1, 500,SubscribedDataChanged);         
        }

        private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
        {
           modbusTCPCom1.Unsubscribe(SubscriptionID);
        }

        private void SubscribedDataChanged(object sender,MfgControl.AdvancedHMI.Drivers.Common.PlcComEventArgs e)
        {
           string mystring = e.Values[0];
         string myaddress = e.PlcAddress;
        }

Thanks

When subscribing with the driver via code, the event is fired every time data is returned, not only when it changes. The DataChanged is only a function of the DataSubscriber component.

Private Sub DataSubscriber21_DataChanged(sender As Object, e As Drivers.Common.PlcComEventArgs) Handles DataSubscriber21.DataChanged

Runs as many time as elements I have in the Datasubscriber PLCAddressValueItems collection, even if their status don't change.
Is that the way it should work?

Found the response in an old post.
