Logical Addressing for Report Generation
Chapter 6
6Ć2
Some examples appear below:
Data Table Address Description
$B1:5 This address specifies binary file, 1, word 5.
$D0:1 or $D:1 These addresses specify the same address, decimal file 0
word 1. If you are specifying file 0, you need not enter a zero
after the section specifier.
$TPRE:57 This address specifies the preset of timer 57.
$B1:5/12 This address specifies binary file 1, word 5, bit 12 decimal.
$B1:5/12 or $B1:5/014 Both addresses specify binary file 1, word 5, bit 12 decimal. In
the second example, 014 represents the octal value for 12. To
enter a value in octal, enter a zero before the value.

For report generation, always enter a leading
zero to maintain the octal addressing format
for compatibility with ladder diagram program
addressing and I/O terminal numbering.

(ladder diagram
programming).
Alternately, by not entering leading
zeros, bits can be addressed in a
decimal format for report generation
