Title: DF1 Error In Version 't'
Post by: AabeckControls on July 07, 2015, 11:37:50 AM

Installed Version 398t, added my existing project, & been working OK but occasionally when debugging it crashes I shows a DF1 error:

This happens on different pages as soon as I click a Pushbutton or click enabled Pilot Light, but not every time , and doesn't replicate on the same button later. Have to Stop debugging then Start again & this time the same object that crashed before works, but later a different object will give the same error, maybe.

When it stops there, hover over WordPos to see it's value, then hover over Result to see how many elements are in the array.

Took a few pages to pop-up, but when the error appeared it showed WordPos = 0 and Result = {Length=0}.

Other results:

BitResult.Length = 1
BitPos = 13
BitResult = {Length=1}
ParsedResult.BitNumber = 13
ParsedResult.NumberOfElements = 1
ExtractData = Nothing
ReturnedData = {Length=0}
ElementSize = 2
ParsedResult.BytesPerElement = 2
StringLength = 0
result.Length = 0
&H8D = 141
&H86 = 134
&H87 = 135
&H88 = 136
ParsedResult = {MfgControl.AdvancedHMI.Drivers.PCCCAddress}

Archie,

This has happened a few more times, always shows WordPos = 0 and Result = {Length=0}.

Here is something to try until I can get deeper into this.

- Open AdvancedHMIDrivers\AllenBradley\AllenBradleySLCMicro.vb
- Go to line 2135, you should see     If e.RawData.Length > 0 Then
- Change that line of code to :

 If (RawResponses(TNSLowerByte).EncapsulatedData IsNot Nothing) AndAlso (RawResponses(TNSLowerByte).EncapsulatedData.Count > 0) Then

Archie,

Did your change & (keeping fingers crossed here) haven't had the error pop-up yet today.

Thanks.
