DNP3 Device Attribute
Object
The Device Attribute object can be used to identify DNP3 Slave devices.
With the controller, some of the variations are written so that you can read or write your own
strings in your application.
The R/W property shows if the object is Read Only, Read, or Write. If the R/W property is
writable, the value which was written by DNP3 master device is stored to non-volatile memory.
The object group of the Device Attribute is 0. The supported range of the variation is 209…255.
