Property

Description

Array expression

Enter the expression which is to return one or more integers. For each returned integer, a different symbol will be displayed.

If the return value is:

  • Less than 0 (zero), it will be set to 0 (zero), and a runtime hardware alarm will be triggered.
  • Greater than 255, it will be set to 255, and a runtime hardware alarm will be triggered.
  • A real (non-integer) number, it will be rounded off to the nearest integer.

To insert a tag or a function, click the Wizard button to the right of this field. This button displays two options; Insert tag, and Insert Function.

Array symbol

The symbol that is to display for each integer returned by the Array expression entered above (symbol 0 will be used when the expression returns integer 0, symbol 1 will be used when integer 1 is returned etc.).

Click the Set button to select a symbol, or Clear to clear the current selection.

For example, to display different symbols illustrating the various states of a motor, you could fill out the Array expression and Array symbol fields as follows:

In this example, MOTOR_STATUS is an analog variable tag representing the status of a motor. Each time the motor changes state, an integer is returned (0 = Running, 1 = Starting etc.), and the appropriate symbol displays.
