Create value displays

Use a value display text object to show the value of a tag. This lets you show things like fill levels, on/off status, or alarm messages.

You can use any one of three types of value display links to show messages at run time.

You can use up to 1023 characters in an expression. If you need a larger expression, create a QuickFunction and call it in your expression.

Messages appear in the location of the original text object using the font, size, color, alignment, and linked attributes set for that object. The original contents of the field have no effect on the message at run time.

Create a discrete value display link

1. Right-click the text object and select Animation Links. The Animation Links dialog box appears.

2. In the Value Display area, select Discrete. The Output -> Discrete Expression dialog box appears.

   

3. In the Expression box, type the name of a discrete tag or an expression that equates to a discrete value. For example:

   Cooling_Pump

4. In the On Message box, type the message to appear when the value of the expression equals 1, true, on, or yes. For example:

   Pump is ON

5. In the Off Message box, type the message to appear when the value of the expression equals 0, false, off, or no. For example:

   Pump is OFF

6. Select OK.

Create an analog value display link

7. Right-click the text object and select Animation Links. The Animation Links dialog box appears.

8. In the Value Display area, select Analog. The Output -> Analog Expression dialog box appears.

   

9. In the Expression box, type an analog (integer or real) tagname or an expression that equates to an analog value. For example:

   Tank_CV*0.06

10. In the Formatting area, in the list, select each data type for which you want to configure run time advanced formatting. The Fixed Width checkbox, Precision box, and Bits From and To boxes become available based on the data type you select. For information on configuring these options, see Advanced formatting for text.

    Note: During run time, the analog value input link field can be resized by selecting and dragging with the pointer and mouse.

11. Select OK.

Create a string value display link

12. Right-click the text object and select Animation Links. The Animation Links dialog box appears.

13. In the Value Display area, select String. The Output -> String Expression dialog box appears.

    

14. In the Expression box, type the name of a message tag or an expression that uses a message tag. For example:

    "The Tank Level is:" + Text(TankLevel,"#")

15. Select OK.

    Note: During run time, the string value input link field can be resized by selecting and dragging with the pointer and mouse.
