Name: Label1, It is the name of the component. Every component will have a UNIQUE number
in a page. If more than one Label is available in the same page, the number will be
incremented automatically. The user can also change name of this component if
required. Component "Name" property is very useful and it can be used in scripts also.
Example: Task: Change Label1 "back" color to blue during Run time when Tag1 is equal to 1.
if(Tag1 == 1)
{
Screen1.Label1.BackColor=Color. Blue;
}
Screen1: It is the location of Label1
Label1: Object name
BackColor: Property of Label related to background color
Color.Blue: Target Color
If the above script is executed in scheduler once per second, then when Tag1 = 1, the back color for Label1
will change to Blue during Run time.
Properties are case sensitive.
BackColor : OK
Backcolor : Not OK
Security Level: Define security level for the component to be used by the operator. If operator
Locked: True/False: It is to Move or Resize the component.
Layout
Dock: Defines which borders of the control are bound to the container.
Location: The coordinates of the upper-left corner of the component relative to upper-left
Size: Size of the component in pixel. Set height and width of component in pixels.
Position: It is the defined position of Label, Value etc., for some components. Available options
include None, Top Left, Bottom Right, Both and Internal.
Position naming convention for components
For example: Level component, Label Position = Bottom Right
If Orientation is Vertical, the Label will be displayed on the Right side of the component.
If Orientation is Horizontal, the Label will be displayed on the Bottom side of the component.

transmitters like Ear level transmitters (sound detectors in ball mills, etc.).
security level is less than security level defined for component, it will not allow
operator to operate the component.
