Open Discussion / Re: combining different registers of a modbus device

« on: April 23, 2014, 03:26:52 PM »

Try this to see if it works for you:

Code: [Select]

    Private Sub DataSubscriber1_DataChanged(sender As System.Object, e As MfgControl.AdvancedHMI.Drivers.Common.PlcComEventArgs) Handles DataSubscriber1.DataChanged, DataSubscriber2.DataChanged
        DigitalPanelMeter1.Value = CInt(DataSubscriber1.Value) + CInt(DataSubscriber2.Value)
    End Sub


Thanks, it seems to work, but I have two new questions:
1) in the property windows of DigitalPanel I have to set up the PLCAddressValue and the CommComponent. Is it possible to set a dummy values for these fields? Sometimes the program launches an exception if I leave the PLCAddress empty.
2) The DigitalPanel shows only integer value but I'm interested to display also the fractionary part
Thanks, again, Vittorio

Open Discussion / combining different registers of a modbus device

hi,
Is it possible to display in a DigitalDispaly control the result of sum of 2 different registers in a modbus device?
I've created two data subscribers (one for registry n. 40022 and one for registry n. 40023) but I don't know how combine it in a single source for the digital panel.
The digital panel only accepts one source and one registry.
thanks, Vittorio
