Quick Access
Addressing

The module provides you with a shorthand method of data file
addressing for default files 3 through 7. Type the file identifier:

%

7 & 5

or

1

then [

(17(5

]. The module displays the first address

within that file.

1. For example, to display the first address in the Integer file:

Press

>6+,)7@ >1@ >(17(5@

The module displays:

2. You can now use the [

1(;7

] and [

35(9

] keys to step through all

the addresses contained in that file. This is explained later in this
chapter.

You may also access a specific element within a data file.

1. To display the Input Image Table word for slot 2:

Press

>6+,)7@ >,@ >@ >(17(5@

2. The module displays the logical address on the top and the on/off

status of each of the bits associated with that word on the bottom
line:

N7:0

123

I1:2.0

0000111100110101

Important:

Input and Output Image Table words can only be
monitored. The Input Image data file represents
external input conditions and cannot be modified by the
module. The Output Image data file is controlled by the
user program and cannot be modified by the module.
