USING VARIABLES
Saving the Initialization File. You must include a carriage return at the end of each line in the
initialization file. In addition, the last line of the file must be blank. If you add comments to the
file, they must be preceded by a backslash (\) and a space. When you have finished modifying the
file, save it as a text file to your strategy directory. You can name the file anything you like. (You
can also save it to any directory you like, but it is good practice to save each initialization file to
the directory of the strategy that references it.)
Downloading the Initialization File
To use the file, you need to download it with your strategy.
1. With the strategy open in Configure or Online mode, click the Configure Controllers button
on the toolbar, choose Configure➞Controllers, or double-click the controller name.
2. Highlight a controller and click the Download Options button.
The Download Options dialog box appears. The initialization file must be downloaded
immediately after your strategy is downloaded.
Download the initialization
file after the strategy.
3. Click the bottom Add button in the Download Options dialog box.
4. Navigate to the initialization file you created. Double-click the file name.
The file appears in the Download Options dialog box.
5. Click OK.
The initialization file sets values for the variables and table elements immediately after
your next full strategy download.
IMPORTANT: When you create each variable, you must check “Initialize on Strategy
Download” in the Add Variable dialog box. See “Adding Numeric, String, and Pointer Tables”
on page 8-7.
Since download options are specific to each controller, make sure you set the initialization
file as a download option for every controller on which the strategy will run.
