Using Cicode Expressions

Cicode expressions are the basic elements of the Cicode language. An expression can be a constant, the value of a variable tag, or the result of a complex equation. You can use expressions to display and log data for monitoring and analysis, and to trigger various elements in your system, such as alarms, events, reports, and data logging.

You can enter a Cicode expression in any CitectSCADA editor form or graphic object that contains an expression property. Unlike a command, an expression does not execute a specific task - it is evaluated. The evaluation process returns a value that you can use to display information on the screen (for example, as a bar graph) or to make decisions. The following expression returns a result of 12:

In the above example, the value of the expression is a constant (12) because the elements of the expression are constants (8 and 4).
