direct logic 05 and ModbusRTU com driver

Your data is coming back in BCD format which uses 4 bits to represent each digit. Hexadecimal does essentially the same thing, but instead of 0-9 it uses the full 0-F and that is why TreatDataAsHex worked. I removed that feature because it was complicating the debug process.

You can make the DigitalPanelMeter use BCD by making this minor change to DigitalPanelMeter.vb at line 326:

Code: [Select]

    Private Sub PolledDataReturnedValue(ByVal sender As Object, ByVal e As MfgControl.AdvancedHMI.Drivers.Common.PlcComEventArgs)
        Try
            MyBase.Value = String.Format("{0:X}", e.Values(0))
        Catch ex As Exception
            DisplayError("INVALID VALUE RETURNED!" & e.Values(0))
        End Try
    End Sub

Awesome.  Thanks Archie. 

I will give that a try and let you know how it works out.

Hey Archie.

I modified the code, but am still getting the same readings.

I have tried to swap the values to look like  (e.Values(0), "{0:X}").  I've tried replacing the {0:X} with just X.  i've tried replacing the X in all variation with D.

Most iterations have no effect on the value displayed in the meter, the rest cause the program to not run.

I am going to keep looking up solutions, but any other ideas you have would be most appreciated.

There are 2 meters, DigitalPanelMeter and DigitalPanelMeterA. Make sure the one you modified is also the one you are using v

I got it to work.

I replaced

MyBase.Value = String.Format("{0:X}", e.Values(0))

with

MyBase.Value = Hex(e.Values(0))

My initial test worked.  now i'm going to let it run for a while and see if it will keep count properly.

Just a quick update.  I let the program run for 5 hours yesterday and everything worked beautifully.  Thanks Archie.
