Controllers and Segments

Controller Card

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.

To print the relationship between
Superloops and controllers...

Go to LD 97, and print the superloops:

REQ: PRT
TYPE: SUPL
SUPL: (hit return)

All Superloops will print.

Next, print the controllers:

REQ: PRT
TYPE: XPE
XPEC: (hit return)

You will see all controllers and which Superloop(s) are assigned to them.

An IPE 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. Here, it would flash C0 and either 01, 02 or 03 depending on what shelf you are looking at, this is its "controller number". This is related to the XPEC assigned to the controller. In this example:

Note: Superloop 4 is split between two controllers/shelves.
