I am trying to simply update on pendant screen the status of a number of digital IO. I have a working solution but the update time on change is in the region >6 secs! This clearly is not workable in real terms. I have invoked the event delegation as recom’d in the sdk docs to sync the threads but even so, i still have very slow updates! Can anyone help / shed some light please…
void ITpsViewActivation.Deactivate()
{
this.do1Sig.Changed -=new SignalChangedEventHandler (do1Sig_Changed);
}
void ITpsViewActivation.Activate()
{
this.do1Sig.Changed +=new SignalChangedEventHandler (do1Sig_Changed);
}
#endregion
private void do1Sig_Changed(object sender, SignalChangedEventArgs e)
{
this.Invoke (new EventHandler(this.ChangedDO1UserInterface),sender, e);
}
private void ChangedDO1UserInterface(object sender, System.EventArgs e)
{
SignalChangedEventArgs args = (SignalChangedEventArgs) e;
SignalState sigState = args.NewSignalState;
Single val = sigState.Value; // or some suitable means of display here
this.textBox1.Text = val.ToString(); // ----------------||------------------
}
