Polling PLC in ASYNC Mode

[Trevor Garvey]

Hi All,

Perhaps someone can help me here. I'm having some issues getting the Ethernet/IP driver to work in ASYNC Mode.

From looking on the topic relating to Subscribe methods here is what I have written…

(My Driver instance is PLC1)
private void timer1_Tick(object sender, EventArgs e)
        {
            PLC1.AsyncMode = true;
            PLC1.ReadAny("N100:0", 50);
            PLC1.AsyncMode = false;

        {

private void PLC1_DataRecieved(object sender, MfgControl.AdvancedHMI.DF1CommEventArgs e)
        {
            s1 = e.Values;
            label2.Text = s1;
        }

For the call back I know this is wrong MfgControl.AdvancedHMI.DF1CommEventArgs but driver has changed since most posts were written on this forum. Does anyone know the correct CommHandler for data_recieved?

You are missing the Handles in your data received event:

    Private Sub PLC1_DataReceived(ByVal sender As System.Object, ByVal e As Driver.PLCCommEventArgs) Handles PLC1.DataReceived
