2. Use the Description: box to enter a title for the Function Key part. A description is not necessary but does
help you identify the purpose of the part.
3. In the ASCII/UNICODE mode section, there are four control key options. Control keys are used during data
entry to perform a specific function.
Function Description
[ENTER] Configures the Function Key as an Enter key. When pressed, it will write the alphanumeric
characters entered into a Numeric Input Object or ASCII Input Object to the target PLC register.
[BACK SPACE] Configures the Function Key as a Delete key. When pressed, it will delete the last alphanumeric
character entered.
[CLEAR] Configures the Function Key as a Clear key. When pressed, it will clear the data displayed in the
Numeric Input Object or ASCII Input Object. Note: this key does not clear the actual target PLC
register until the Enter key is pressed.
[ESC] Configures the Function Key as an Escape key. When pressed, it will exit the editing mode.
4. Just below the four control key options, is the ASCII/UNICODE checkbox. Select this when you want to
configure the Function Key to enter an alphanumeric character. When this checkbox is selected, the
character box is activated. Use this box to enter the ASCII character you want to use.
5. Click the Shape tab to select either a shape or bitmap to represent the Function Key.
6. Click the Label tab to display the Label for the Function Key. Click the Use label checkbox to use a label.
7. Click OK. The New Function Key Object dialog closes and the main screen of EasyBuilder appears with the
cursor tied to a rectangular outline of the part you just created at the upper left corner of the screen. Move
the part to the desired location on the window and click the mouse to place it.
8. Once the part is placed onto the window, you can adjust the location of the label inside the part by clicking
once on the label. This will highlight the entire object. Now click on the label again. Now only the label is
highlighted, allowing you to move it without moving the part.
9. Create a Function Key for each number, Enter, Back Space, Clear, and Escape key.
10. Add a display to the keypad by selecting Objects > Numeric/ASCII > ASCII Display. Configure the ASCII
Display with a Read Address of LW9150, and six words (No. of words). Place the ASCII Display above the
Function Keys to complete the keypad.
To create a custom keypad, group all of the keypad objects together on a window. You can then save the keypad to a
group library for later use in other projects. Several predefined keypads are included with EasyBuilder. To use these
keypads, click Library > Group > Call up Library in EasyBuilder-5000 and access the keypad library.
Alternately, you can create a custom keypad in a graphics program such as Paint and import it into the Picture
Library. Place the picture on a window using the Draw > Picture tool, and overlay the Function Keys and ASCII Display
on top of the picture. The computer.flb library has some keypad pictures you can use (picture no. 35 and 36).
Displaying and Using a Keypad
Let’s go through a sample project that uses one of the predefined keypads included in EasyBuilder to enter values in a
Numeric Input Object and an ASCII Input Object. This example will show you how to place these objects on a window
screen, and then use the keypad to edit the data registers.
