E-6 Data File Organization and Addressing
You can also address at the bit level using mnemonics for timer, counter, or
control data types. The available mnemonics depend on the type of data.
I/O Addressing for a Fixed I/O Controller
In the following figure, a fixed I/O controller has 24 inputs and 16 outputs.
An expansion chassis has been added. Slot 1 of the chassis contains a module
having 6 inputs and 6 outputs. Slot 2 contains a module having 8 outputs.
The following tables show how these outputs and inputs are arranged in data
files 0 and 1. For these files, the element size is always 1 word.

Some programming devices support short addressing. This allows you to eliminate the file number and file delimiter from addresses.
Consult your programming device’s user manual for information on addressing capabilities. (For example: N7:2 = N2; T4:12.ACC =
T12.ACC; B3:2/12 = B2/12)
