Controllers and Segments
The image right is a NT8D01 controller card. It's installed in each IPE shelf between slots 7 and 8, and interfaces upto 4 Superloops to an IPE module.
See also Network Loop Configurations and Superloops / Controllers.
An NT8D37 IPE Module is divided into four segments of four card slots, numbered 0-3. Segment 0 consists of slots 0-3, segment 1 consists of slots 4-7, segment 2 consists of slots 8-11, and segment 3 consists of slots 12-15. A superloop can be assigned from one to eight IPE segments.

Superloops and controllers...
Go to LD 97, and print the superloops (SUPL) and the controllers (XPE).
You will see all controllers and which Superloops are assigned to them.
Print the superloops:

An IPE module (shelf) is split into 4 segments. A superloop can service from 1 to 8 segments. The controller is the IPE card between slots 7 and 8. In this example, the controller faceplate display would alternate between C0 and either 01, 02 or 03 depending on which IPE shelf you're looking at: this is its "controller number", and is related to the SUPL assigned to that controller. In this example:
- Loop 4, Shelf 0 = Controller 01, segments 0 to 3 (XPEC 0)
- Loop 4, Shelf 1 = Controller 02, segments 0 to 3 (XPEC 1)
- Loop 24, Shelf 0 = Controller 03, segments 0 to 3 (XPEC 0)
