Hi Mikko

When reading extended register using short-code referencing.

GXDLMSExtendedRegister max_demand = new GXDLMSExtendedRegister("1.1.9.6.1.255", 54000);
Object Demand = comm.Read(max_demand, 2);

I am getting error (Input string was not in a correct format)

When i check the GXDLMSExtendedRegister object its in the correct format.
/// <summary>
/// Constructor.
/// </summary>
/// <param name="ln">Logical Name of the object.</param>
/// <param name="sn">Short Name of the object.</param>
public GXDLMSExtendedRegister(string ln, ushort sn)
: base(ObjectType.ExtendedRegister, ln, 0)
{
}

Can you point me in the right direction please.

Hi Keenan George,

You have found an issue from our code. :-)
Most of meters are using Logical Name referencing at the moment.
For some reason short name is given as zero.

We have fixed this. Get latest version.

BR,

Mikko
