Attention!

If the value of an element falls into several intervals at once, the indicator accepts a value according to the rule with the smallest number among the suitable ones.

To save the changes, click the Apply button.

Indicator and its value are displayed on the map (see Working with OPC-server elements of Data Access standard on the map).

Let's consider the work of this rule on an example.

There are three intervals of element values depending on which the indicator takes a certain proportional value and color. To calculate the exact value of the indicator, use the following formula:

  

where V is the exact value of the element.

For example, if V=1300, then the indicator value

 

the indicator color is red.

If V=2200, then the indicator value

 (approximated),

the indicator color is blue.

Configuration of the rule of changing the indicator state is complete.
