I/O Allocations

J CompoBus/S and Special I/O

Allocations

When allocating I/O in CPU memory, CompoBus/S is

considered a Special I/O Module. These modules can be

mounted to the CPU Rack and Expansion Racks. Each

CompoBus/S Module is allocated ten words in the Special

I/O Module Area (CIO 2000 to CIO 2959). Refer to the

table provided to the right.

Note: During I/O allocation to Basic I/O Modules, Special

I/O Modules are ignored. (Slots containing Special

I/O Modules are treated as empty slots.)

J Allocations for All Networking and

Communications Modules — Except

CompoBus/S

Each CPU Bus Module is allocated 25 words in the CPU

Bus Module Area (CIO 1500 to CIO 1899).

CPU Bus Modules can be mounted to the CPU Rack or

Expansion Racks.

Each Module is allocated 25 words in the CPU Bus Module

Area according to its unit number, as shown in the table to

the right.

Note: CPU Bus Modules are ignored during I/O allocation

to Basic I/O Modules. The same unit numbers can be

used for Special I/O Modules and CPU Bus Modules.
