Word Allocations
Allocating First Words to Slots (Single CPU Systems Only)
Note The first words for slots cannot be set at the same time as the first words for

With a Single CPU System, the first word allocated to a slot on any Rack can
be set with the CX-Programmer’s I/O table edit operation regardless of the
position of the slot. This feature can be used whenever it’s necessary to con-
trol allocations to specific Units, e.g., to group allocated I/O words by device or
circuit.
The first word can be set for up to 64 slots.
Racks.
When setting first words for slots, the first word must be set for slot 00 on the
CPU Rack. The first word can then be set for any slot on any Rack for up to 63
other slots.
Each first word set for a slot creates a group starting with that slot. Words are
allocated starting from the specified word to the first slot in the group and con-
tinuing left to right allocating consecutive words to each Unit until the next
group (i.e., until the next Unit for which a first slot word is set). The next group
can start on the same Rack or on a following Rack.
• Be sure to make first word settings so that allocated words do not overlap.
• Always register the I/O table after installing an I/O Unit, after setting a rack
• I/O words will not be allocated to empty slots. If an I/O Unit will be

The first word setting for a rack can be any address from CIO 0000 to

so that the number of words or I/O type does not match the I/O table, an

and the I/O Table Registration Operation will have to be performed again.
