Note Rack numbers (0 to 3) are fixed according to the order that the Racks are

physically connected with cable. The CPU Rack is always Rack 0 and the

other Racks are, in order, Racks 1 to 3. These numbers cannot be changed.

The first word allocated on each Rack can be set from the CX-Programmer.

These settings are not possible from a Programming Console.

been set will be displayed on a Programming Console.

First Rack word set to CIO 0100.
