Hello.

The DateTime you pass into this method must be in UTC: Use ToUniversalTime or SpecifyKind method as needed.

The error message is not good enough, and we will fix in the next version.

Best regards

I am trying to write a value to my historian with a DateTime (which I guess makes it HDA, not DA) and it gives an obscure error.

Message: "timestamp"

I guess this means writing a date/time with the value is not supported, as that would be HDA? Do you have a tool that supports HDA?

static DAVtq WriteOPCDAVtq(string MachineName, string ServerName, string ItemID, object value, DateTime dateTime)
{
EasyDAClient easyDAClient1 = new EasyDAClient();

try
{
easyDAClient1.WriteItem(MachineName, ServerName, ItemID, value, dateTime, 192);
}
catch (Exception Ex)
{
Console.WriteLine(Ex.Message);

LogError(Ex);
}

return null;
}
