The SCADA 3000 includes a 4-line by 20-character liquid crystal display (LCD) and a

4-button keypad on its front panel. The display is used for viewing the values of data points,

checking system information, and acknowledging alarms. It has two modes of operation:

scrolling and manual. In scrolling mode the display will scroll through a programmable list

of data points, showing 4 at a time. Every 5 seconds it will change to display the next set of

points. You can customize the display to show only the points pertinent to your application.

The keypad is used to manually view specific information, acknowledge alarms and program

the data points that appear when the display is scrolling. You can also program the scrolling

data points from the SCADA 3000 software.

Display Backlight

An LED backlight is integrated into the display to allow viewing in dark environments. To

turn on the backlight, simply press one of the keypad buttons. The backlight will come on for

a few minutes, then shut off automatically to save energy.

DATA POINTS

Programming Data Points for Scroll mode

Click on the LCD button from the toolbar on the main programming form or select

Programming then LCD from the main menu. The following form should appear:

Figure 1: LCD Programming Form

This programming form is used to select the data points which will scroll on the LCD display.

The box on the left provides a list of all the data points that can be chosen for display. The

box on the right shows the data points that have been selected to appear on the display. In this

process you will be choosing items from the list on the left and copying them to the list on

the right. In the drop-down box next to the heading “Available UAFs,” choose the data point

category by clicking on the down arrow. The choices are: Inputs, Outputs, Timers, Counters,

Bits, Ladder Variables, C Variables, Alarms, and Diagnostics. When you pick a category a list of

all possible points in that category will appear. Click on the item you wish to add to the scroll-

ing display and then click on the Add to List button identified by the arrow pointing to the

right between the boxes. This will copy the highlighted item to the list of Selected Data Points

(“Selected UAFs”) on the right (i.e., those to appear on the LCD). Continue this process by

highlighting each data point on the left and copying it to the list of Selected Data Points on

the right. When you have finished making your list, click on the Commit button. This will

upload the list to the SCADA 3000 and it will immediately start displaying the programmed

data points on the display. Note that the unit defaults to having all of the main unit inputs and

outputs selected for display.
