Orange 241

The 241^st color in the VTS palette is a special shade of orange that has been designed to react to the Image Change drawing method for tags. This specialized shade of orange is indicated by the mouse pointer in the image below.

The RGB values that combine to create this specialized orange shade are R=255, G=160, and B=0. This shade of orange has been specially configured to be combined with the Image Change tag drawing method (available to digital input, digital output, alarm, function and modem tags) to display in color the state of the related tag. When the Image Change drawing method is employed without the use of a bitmap for one or more states, the resulting color indicator will react when placed over any image or portion of an image drawn using the orange 241 color.

The following image illustrates this action:

In this example, four simple squares have been drawn (using the rectangle tool), each in a different shade of orange chosen from the VTS palette. The square on the lower left has been drawn using the orange 241 shade. The Image Change drawing method was then used to draw a digital input tag. The Image Change object was positioned in such a way that it intersects all of the orange squares.

As shown, only the square drawn using orange 241 reacts with the Image Change object to change as the value of the tag changes. (In this example: red.)

This feature can be employed in a variety of different ways. For example, you might wish to use an area map, plant map, or other background image that has been drawn using patches of the orange 241 color in specific areas. Having selected the image as the background for a page in your VTS application, you may then overlay its orange 241 sections using Image Change objects. The result is that these areas will change in color according to the value of the tags related to the Image Change objects.

Another use is to create your own equipment bitmaps that have areas highlighted using the orange 241 color. You can then add these equipment bitmaps to your VTS application directory, place them on your application's pages, and layer them with Image Change objects. The result is that the delineated portions of the equipment bitmaps will change color when the related tags change color. An example follows:

These images demonstrate the reaction of a bitmap that includes the orange 241 when combined with the Image Change drawing method for a digital input tag.

 1.   A valve bitmap whose base has been drawn using the orange 241 color from the VTS palette.

 2.  An Image Change object (red) has been placed over the orange 241 shaded area of the valve bitmap.

 3. and 4.   The area of the bitmap, drawn using the orange 241 shade, now changes color according to the value of the tag.
