CREATING & EDITING MACROS

You can make your macros as simple or complex as you want. For a guide to all macro commands, operators and
expressions, see MACRO SOURCE CODE on pages 94-96.

Creating a New Macro

To create a new macro, open the Macro Editor and select an empty macro entry from the drop-down list. The
programming window will be blank, and you can then enter source code from scratch. If all of your macro entries
are in use, you can either program the macro on a different unit with empty macro positions, or select an existing
macro and replace it with new source code.

In order to be properly identified by the I/O unit, the first line of all macros must consist of the word macro
followed by the name of the macro in quotation marks, All macros must conclude with the end statement “mend”
on the last line (for macro end).

Editing an Existing Macro

To edit a macro that is already saved to the I/O unit, select the desired macro from the drop-down list. The
programming window will open, and you can edit the macro’s source code as needed.

Note: Editing macros requires system or operator privileges.

Entering Source Code

Entering text in the macro editor is straightforward. You will find standard text editing functions in the Edit menu,
and there are toolbar shortcuts for cut, paste, copy, indent/outdent and undo. At any time during the editing
process, you can check the macro syntax by clicking the Check Syntax

icon. The macro editor will verify that

the source code has been entered correctly.

Note: The Macro Editor automatically checks syntax before it saves the macro to the I/O unit. The manual Check
Syntax function is useful if you would like to make corrections as you edit, rather than after writing the entire macro.

Within the body of your macro, you can insert remarks within single-quotation marks separated from the macro
syntax by a colon:

If Status(9) = Low Then : ‘IF NO AC POWER’
Command Me, Me, 14A : ‘TURN BREAKER ON’
Command Me, Me, 11A : ‘DIRECT POWER TO AC’

Remarks can be used to clarify each step of the macro, or to explain to other operators how macro works.

Saving Macros to the I/O Unit

When you are finished creating or modifying macros, save them to the I/O unit by clicking the Save to Unit
icon in the Macro Editor toolbar. A pop-up window confirms a successful save.

Note: Any currently running macros will be stopped when you save new macros the I/O unit. To manually restart
them, open the Macro Status window, select the desired macro, and click Run.

If you wish to save a copy of your macro to disk, use the select all function from the Edit menu and copy the
contents of the programming window into a text file (such as a Notepad document). Then save the text file to
your computer or floppy disk. This method allows you to save a work-in-progress macro for future editing. To
continue working on the macro, open the text file and copy the macro back into the Macro Editor.
