The manner by which the I/O associated with a polling driver or Data Flow RTU are sorted on a station page (i.e. alphabetically or numerically) is controlled by the configuration of the Site Draw drawing method used to draw station symbols.
To set the order of the I/O associated with a polling driver or Data Flow RTU alphabetically on a station page (sorted alphabetically by each tag's Description property), follow the instructions included below:
Note: The instructions below will guide you through the process of drawing a polling driver or Data Flow RTU driver tag on a page using the Site Draw Drawing Method, as clicking the resulting station symbol is the means by which a station page or custom page is accessed. If you have already drawn the polling driver or Data Flow RTU driver tag using the Site Draw tag drawing method, you may modify its settings by clicking the Configure button, right-clicking the station symbol, and proceeding to step 8 below.
1. Open the page upon which you wish to draw the polling driver or Data Flow RTU driver tag as a station symbol (typically the Overview page).
2. Click the Configure button to open the Configuration Toolbox.
3. Click the Browser button to open the Tag Browser.
4. Select Drivers from the Types drop-down list (the Drivers tag group appears quite far down in the Types drop-down list).
5. Select the polling driver tag or Data Flow RTU driver tag representing the station that you wish to draw, and for which you wish to establish the order of the I/O on the associated station page.
6. Click the Draw button. The polling driver or Data Flow RTU driver tag drawing methods will be displayed.

7. Click the Site Draw button. The Site Draw dialog will open similar to the one displayed below.

8. Select the Alphabetical Sort Order radio button.
9. Click the OK button. The station symbol will be attached to your mouse pointer.
10. Position the station symbol on your page.
11. Click to drop the station symbol. The Tag Browser will reopen.
12. Close the Tag Browser.
13. Close the Configuration Toolbox.
You may now click the station symbol you just drew to view the associated station page. The I/O will be sorted alphabetically in the appropriate portions of their respective columns (i.e. Analog status tags from a-z by Description, and then pulse input tags from a-z by Description in the first column. Digital status tags from a-z by Description, and then pump status tags from a-z by Description in the second column. Finally, digital control tags from a-z by Description in the third and fourth columns).
