Marc,
Blocks are always internal. ?Blocks derive their occupancy state from assigned sensors.

Phil,? I see you posted you attachement as a Photo in Photos
IB are internal blocks, and I believe? not physical blocks on the layout or test track.? So you must trip these manually unless the IB1, IB3 have sensors attached to them.
Usually those physical to layout blocks would have LB (if Loconet)? or NB (If NCE).
