Unsigned tag types are not yet supported, but I will look into getting this implemented in the next beta version.

Unsigned types were added to the 5580/5380 platform only, v32 and above.  Also, Micro800 series.  I'm sure you already know but data types for reference (forgive the extra nonsense):


--- Code: ---0xc6: (1, "USINT", '<B'),
0xc7: (2, "UINT", '<H'),
0xc8: (4, "UDINT", '<I'),
0xc9: (8, "LWORD", '<Q'),
0xcb: (8, "LREAL", '<d'),

--- End code ---

Edit: Maybe you are already supporting those types and you were referring to adding support for read/write UDT specifically.  My bad if that statement is true...

I thought it needed to be implemented for both reading individual tags and parsing when Reading/writing UDTs, but after looking I see support for those new tag types were already implemented when reading them individually. So only parsing the UDT byte steam into equivalent classes needs to be implemented.

After I had posted, I thought I remembered us discussing this when v32 first came out.  I remember borrowing hardware to test this in python.

I need read a Array of UDT with size 10, in C#.
I have a error in command .ReadUDT. See attachments.

 public struct UDT
        {
           
            public Int32 Yr;
            public Int32 Mo;
            public Int32 Da;
            public Int32 Hr;
            public Int32 Min;
            public Int32 Sec;
            public Int32 uSec;
        }

        UDT[] Dates = new UDT[10];
           
           Dates = CLXCom.ReadUDT("Dates",10);

Godra:
Your code should probably be more similar to this:


--- Code: ---        public struct TimeUDT
        {
            public int Yr;
            public int Mo;
            public int Da;
            public int Hr;
            public int Min;
            public int Sec;
            public int uSec;
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            var Dates = CLXCom.ReadUDT<TimeUDT>("Dates[0]", 10);
        }

--- End code ---
