In the editor view, all project variables can<br />

be seen and changed if necessary.<br />

Variables can also be inserted here.<br />

All variables from this view always appear<br />

in the variable selection dialog box list.<br />

If a variable is changed or deleted in this view, it is also changed or deleted in the corresponding application<br />

objects!<br />

4.3.7.1.1 Insert variable<br />

A variable is inserted by pressing the 'INS' key. The variable dialog box is opened and a variable can be<br />

selected from the existing application program resources. It should be noted that some PLC variables are only<br />

available after compilation. Variables from IEC languages are immediately available (also see Variable Selection<br />

Dialog Box).<br />

The inserted variable is displayed in the overview. From this point on, it is available in the 'Data Point' combo<br />

boxes for individual objects.<br />

4.3.7.1.2 Delete variable<br />

A variable is deleted by selecting it and by pressing the 'DEL' key. If the variable is still in use, then a warning<br />

message is displayed. Once deleted, a variable is also removed from corresponding objects. This can also<br />

cause errors during compilation.<br />

4.3.7.1.3 Modify variable<br />

If a variable is used several times in a project, it can be changed to another variable in the variable dialog box.<br />

This can replace editing individual objects on different pages.<br />

Double−clicking on the variable name opens the variable dialog box with the current variable. Another variable<br />

can be selected from this window.<br />

Warning:<br />

It should be noted that not every variable data type can be connected to every field. Incorrect data type<br />

assignment causes an error when the project is compiled.<br />

4.3.7.2 Variable View by Picture<br />

Arranging variables according to picture allows for quick orientation within a project. This list can also be saved<br />

in an ASCII file and further edited. This list can be used for coupling an INA2000 client FBK to other B&R<br />

systems.<br />

The list view can be displayed for all or individual pictures.<br />

In the example above, the view has only been selected for the INIT_PIC. Selection is made by name in the<br />

combo box.<br />

The following information is displayed in the columns from left to right:<br />
