Compact 8Ćpoint Addressing Example

I/O Group 0 I/O Group 1

- 4 Analog modules = 1/4 logical rack = 2 I/O groups

2 module positions = an I/O group

Legal Module Placement in 16Ćpt Compact Addressing

A 16Ćpoint input module and a 16Ćpoint output module

(or an empty slot) in an I/O group

Note: Shaded areas represent unavailable data

I/O groups 4-7 are available for another adapter.

Note: When using block transfer modules in 16Ćpt compact addressing, address module positions

M0, M2, M4 and M6 as module 0" in a block transfer instruction block; address module positions

M1, M3, M5 and M7 as module 1" in a block transfer instruction block.

An empty slot and any module (or another empty slot)

in an I/O grouop.

A block transfer module and another block transfer module

(or an empty slot) in an I/O group.
