You

assign logical addresses to instructions from the highest level (element) to the

lowest level (bit). Addressing examples are shown in the table below

To specify the

address of a:

Use these parameters:

Bit files are bit stream continuous files, and therefore you can

address them in two ways: by word and bit, or by bit alone.

Bit within a structure file

➀

Some

programming devices support short addressing. This allows you to eliminate the file number and file

delimiter from addresses. (For example: N7:2=N2, T4:12.ACC=T12.ACC, B3:2/12=B2/12

)

Consult

your

programming device’s user manual for information on addressing capabilities.
