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.
