Significance of DIR-DIR link direction in DMS object link

[Former Member]

How exactly the DIR-DIR link is controlled by direcetion? (Active/Passive/Two way)

And why the classification object with class 048 is not provided for DIR-DIR link like other objects? Is there any other way to classify this link?

I just need to know how DIR behaves when it is Active or Passive in DIR-DIR link.

I am not able to find out the difference between Active/Passive/ Two way direction in DIR-DIR link.

What functions are Enabled/Disabled when for the DIR when the it is Active/Passive?

points rewarded accordingly.
