"2 state" versus "4 state". Not all tags will have all the states shown in these examples. Alarms have only state 0 and state 1 and therefore must use the "2 state" version of this widget.
Digitals might only use two states, but they can have four and therefore must use the "4 state" version of the widget.
The Color Blink tag widget is used to create a color box that blinks to indicate the state of the underlying tag. Blinking is an extremely eye-catching visual feature and should only be used in situations where it is of utmost importance for an operator to notice the state of a tag. Do not use this widget casually.
You can configure two colors for each state: the status color, and the blink color. The widget will alternate between these colors according to the On Time and Off Time configured for each state.
If one of the colors is left unconfigured, or set to transparent, the object will seem to appear and disappear. If the colors are identical, nobody will notice the blinking. In general, it is best to use either a light and dark shade of the same hue, or to leave one of the colors transparent or unconfigured.
If a page is intended to be viewed on a VTScada Thin Client, it is recommended that Color Blink objects and Animated Bitmap objects not be used. This is due to possible latency and bandwidth issues. If you must use Color Blink objects, please ensure that you set slow blink rates.

The color blink widget is used most effectively with digital tags, or tags that have binary states such as alarms. If used with an analog tag, the tag’s value will be rounded to obtain the closest value of 0, 1, 2 or 3 (repeating).
