Title: OverflowException in 3.98f - AllenBradleySLCMicro
Post by: calimero100582 on April 22, 2015, 12:03:47 PM

When I try to write to a big array[200], I have an OverflowException in WriteRawData

Code: [Select]

TNS = ProtectedTypeLogicalWrite(Convert.ToByte(DataW.Length), Convert.ToByte(PAddress.FileNumber), _
                                              Convert.ToByte(PAddress.FileType), Convert.ToByte(PAddress.Element), Convert.ToByte(PAddress.SubElement), _
                                             DataW)

in my case, PAddress.SubElement = 328

This will be fixed in the next release of 3.98g or higher. The current work around is to break the reads up into 100 or less elements.

Thanks

Another quick question, SLC aren't supposed to support address like N59:11/7 to read single bit?

They should support that addressing scheme. I will test it later to make sure AdvancedHMI can still read that format with the new SLC driver.
