The following list shows the possible ways you form memory addresses:
$ wordaddr
$ wordaddr/bit
$ wordaddr,size
$ fileaddr:wordaddr
$ fileaddr:wordaddr/bit
$ fileaddr:wordaddr,size
$ extaddr
& imblock
Important: The numbers you enter into the fields when addressing
memory are interrupted as decimal (base 10) unless you indicate that they
are octal (base 8). You can specify an octal number by starting it with a
zero. For example, 17 is interpreted as decimal 17, but 017 is interpreted
as octal 17 (or decimal 15). In all of the examples that follow, we will use
a leading zero to indicate octal addresses. Some addresses, however, are
always interrupted as octal.
Addressing a Word
This section provides examples of addressing a word in each PLC–2,
PLC–3, and PLC–5 memory.
To address a
single word in:
Use this format: Examples:
PLC-2 memory $wordaddr $010 (specifies the word at address 010)
PLC-3 memory $fileaddr:wordaddr
or
$extaddr
$B11 1:1 (specifies word 1 of binary file 1 11)
$E3.1.8.11
1.0.1 (extended addressing)
PLC-5 memory $extaddr $E0.10.2.0 (specifies word 2 or integer file 10)
