You can specify an octal address format for extended addresses by entering
a leading zero in the bit position of the address. Using this format can
make your report generation procedure compatible with ladder diagram
program addressing and I/O terminal numbering. Figure 6.1 shows how the
bit numbering formats in report generation correspond to the bit numbering
format within a PLC–3 memory word.

Some examples appear below:

Extended Address

Description

$E3.1.2.3.0.0

This address translates to the data table (3), context (1), input

image table (2), file (3), structure (0), and word (0).

$E3.1.8.1.0.5 or $B1:5

These addresses specify binary file 1 word 5.

$E0.0.0.17

$E3.1.8.0.0.1/10 or

$E3.1.8.0.0.I/O12

This address specifies system status area hour storage word.
To access the system status area, you must select privilege 0 in

LIST. Refer to chapter 4 for detailed information on selecting

privileges.
These addresses specify to bit 10 of the data table area, binary

file 0, word 1, bit 10. The octal value 12 is 10 decimal.
