Ibrahim -

The former has all activities on separate rows whereas the latter will have activities related to similar deliverables, control accounts or other "higher" WBS nodes on the same row.

If you Google for "Time-scaled logic diagram" you will see examples created in Primavera P6.

It's just a different method of visualizing the same content...

Time Scaled Schedule Network is a barchar. Lenght of the bar represent the activity duration. There is no relation between the activities, Just bars that shown the activities duration. Time-Scaled Logic Diagram is a barchar with activity relations into it. For example arrows will link bars to show activity relations.
