Attributes

Ethernet Backplane Diagnostics object attributes are associated with each instance, as follows:

Instance ID = 0 (class attributes):

Attribute ID hex	Needed in Implementation	Description	Value	Data Type	GET
01	Required	Revision of this object	The current value assigned to this attribute is 1.	UNIT	X
02	Conditional⁽¹⁾	Maximum instances	The largest number of instances of a created object at this class hierarchy level.	UNIT	X
03	Conditional⁽¹⁾	Number of instances	The number of object instances at this class hierarchy level.	UNIT	X
(1) Required if the number of instances is greater than 1 X = supported

Instance ID = 1 (instance attributes):

Attribute ID hex	Needed in Implementation	Description	Type	NV	GET	Value
