Description

Table

This table represents the mapping of the memory area selected with the Memory Area selection buttons.

The occupied memory addresses are marked by dashes:

  • blue: for module type objects

  • red: for objects entered in the program

  • green: for objects defined in the variable editor

The scroll bars can be used to access the entire memory area.

Modules , Variables , and Language check-boxes

These check-boxes are used to filter the information displayed in the table. If for example, Modules is the only checkbox that is selected, only module-type information is displayed.

Address information

By entering the object and its address in the Address fields and clicking the Go To button, you display directly the address in the table (without using the scroll bars). This zone also has a display function; it displays the object and address of the box selected in the table. For module-type objects, it also gives the topological address of the module concerned.

Memory Area selection buttons

These buttons are used to select the memory area to display in the table:

  • %M (0x) output bits and internal bits

  • %I (1x) input bits

  • %IW (3x) input words

  • %MW (4x) output words and internal words
