To create the ability to change window security level
1. Create a window(s) that contains a Numeric Input Object. For more information on creating a
Numeric Input Object, see “Representing PLC Data Registers” section in Chapter 6.
2. From the Parts menu, click Numeric Input . The Create Numeric Input Object dialog box
appears.
3. In the Read address frame, select local word LW9040 . LW9040 is a reserved internal data
register of the OIT that is used to change the window security access level.
4. Select BIN (binary) format. Select No. of words: as 2.
5. Click the Numeric tab to display the Numeric form.
6. In the Display attribute box, select Decimal display or, if you wish to prevent others from
seeing the password code, select Mask display.
7. Then create a numeric keypad to allow entering numbers into the Numeric Input Object, (see
Chapter 7 – Using and Creating Keypads).
Two additional local word registers are used to support the Window Security Level feature:
· LW9042 is a 16-bit Read Only register which always shows the current window security level: 0, 1, or 2.
· LW9043 is a 16-bit Read/Write register that quickly ‘forces’ the window security level to a lower level by
entering the level number. For instance, if the current security level is Level 2 (the highest security level),
you can move quickly from this level to Level 1 or Level 0 by entering the number 1 or 0 respectively into
this register- no password is required. This feature enables someone who has the highest security level to
switch the OIT to a lower level without having to memorize all three passwords.
As signing Un der lay Win dows
EasyBuilder allows you to assign up to three underlay windows to any base window that you are creating. First,
create the underlay window; then select it from the pull-down list box when you change the settings of the base
window.
How to Dis play Un der lay Win dows
When you have common objects to display on multiple screens, use the Underlay Window feature to store these on
underlay windows attached to a base window. This decreases the amount of memory required for the project. The
base window “calls” the underlay window. Each full-size base window can display up to three underlay windows,
which are called Underlay #1, Underlay #2, and Underlay #3. Objects on the underlay windows cannot be edited
from the base window on which they are displayed.
A pop-up window cannot display any underlay windows.
To assign underlay windows to a base window, you must first create the underlay windows. Underlay windows are
created the same way base windows are created. Then you can assign the underlay windows to the base window.
