DLMSDirector

Hello,

I am trying to write an attribute, but whatever the value I enter in the field, DLMSDirector sends value 0 to my device.

See below log, where I wanted to write value of 900 to my Demand Register period attribute (8). I typed 900 in the GUI filed, then press enter (I hear the Windows bell sound).

I then click on the Write icon, and see the data being sent to my meter but value is 0 instead of 900.

On thing important is that my meter does not implement attribute 2 of Association LN object, so I created objects manually in the xml config file :

Kind Regards,

angmokio
