Description

Note: This option is only available while

editing UDFB C/C++ source (*.c) and header (*.h) ﬁles.

Also, note that the Undo buffer is only one level deep: it only contains the last keystroke . Selecting Undo twice will perform a ‘double-undo’, or redo.

Restores what you are working on to the way it was before your very last action. For example if you overwrite a line of code, this command will remove your edits and restore the line as it was before you began.

Removes the selected objects and places them in a temporary ﬁle. This material remains in the temporary ﬁle until overwritten by subsequent Cut or Copy actions, or until you close LogicPro.

The Cut feature works the same way when working with UDFBs, except that the data is stored on the Windows Clipboard, not the LogicPro temporary ﬁle.

Creates a duplicate of the selected object without removing it (see note below), and places it in a temporary ﬁle. This material remains in the temporary ﬁle until overwritten by subsequent Cut or Copy actions, or until you close

LogicPro.

The Copy feature works the same way when working with UDFBs, except that the data is stored on the Windows Clipboard, not the LogicPro temporary ﬁle.

Places the content of the temporary ﬁle into the active window at the insertion point. If you are pasting in a UBFB, it is the content of the clipboard that is placed in the active window.

Pasting does not clear the temporary ﬁle. The last item placed into it stays there until subsequent Copy or Cut actions, or until you close LogicPro.

Searches the active window for a speciﬁc variable.

Searches the active window for every instance of a speciﬁc value and replaces it with a new, user-deﬁned value.

Description

Deletes the selected area from the active window. This operation cannot be undone.

Opens a dialog box and allows you to manage the different kinds of variables. Select the variable type from the following list:

Project… Resource… Program…

Changes the attributes of an object within an existing project.

Modiﬁes the different conﬁgurations dependent on your selection from the following submenu:

Resource… Driver… Program… Action… User Defined Function Block…

NOTE! Changes to variables within LogicPro (such as

Add, Edit, or Delete) take place immediately and do not depend on a Program save.

Cut, Copy and Paste functions are available primarily with text and cannot be used with most graphical program objects. To test if an object can be cut, copied or pasted, select it then select the Edit menu item to see if the Cut and Copy selections are available.

You can only paste cut or copied elements or text into a window of the same type. For example, if you copy a rung from a ladder diagram you can only paste it into a ladder diagram. LogicPro disables the paste function if you are in a different language type window.

Ladder Diagram language for the active window.

FBD - This option selects the Function Block Diagram language for the active window.

The selected language determines the options for the rest of this menu. The options displayed correspond directly with the tools available from the different Language Toolbars. For more information, please refer to the appropriate section concerning the language you wish information on.

NOTE: Once you select a language and start to build a program, LogicPro prevents you from changing the language as long as any element exists in the window.

UDFB (User Defined Function Block) Menu

This menu gives you control over the various tools available when you’re creating or editing a UDFB. There are compile and build options available for both execution and simulation purposes because each creates its own variant of the UDFB and saves it in the corresponding library. See Table 2.5 on page 13 for a detailed list and explanation of the items on the UDFB menu.
