3–17Addressing Modes for Your Remote I/O

• When using double-slot block-transfer modules:
– The left slot of the two corresponding I/O groups must be
empty.
– You can place any single-slot I/O module in the right slot
of the two corresponding I/O groups.
When using single-slot block-transfer modules, the corresponding
I/O group must be empty.
The following rules apply when you assign I/O rack numbers:
When you select 1-slot addressing, set switches of switch assembly
S1 to assign the first I/O rack number of the chassis. The remote I/O
adapter module automatically assigns the next higher I/O rack
number to the remaining I/O groups of the chassis.
For example, if you want a 16-slot chassis that you set for 1-slot
addressing to begin with I/O rack number 0, set switches of switch
assembly S1 for I/O rack number 0. The adapter module
automatically assigns I/O rack number 1 to the remaining I/O groups
of the chassis (Figure 3.15).
