LED controls display an image file based on the value found in a LANServer Data Array.
These controls are configured with the name of a Data Array in the LANServer and an
offset into that array. If the value found at that location is zero then the so called ‘off’
image file is displayed. If t he value is non-zero then the so called ‘on’ image file is
displayed.
The web project designer can also specify the following properties
• Size: Limit the width of the control to a specific pixel count or allow the control to
use as much space as is required to display the image files.
If the control display’s in grey then this means that there is no valid live data for the
control and its state should not be trusted.
This is an image file
which was created to
say ‘
Alarm’.
The on and of f image files do not
have to bee the same size.
The image f ile specified cannot be
found so it cannot be displayed.
The ‘X’ in an empty frame is how
you tell that the image file cannot
be found.
