Configure a basic SA_VariableMonitoringBars symbol using ArchestrA attributes

The basic configuration of a SA_VariableMonitoringBars symbol shows 10 charts bars oriented vertically. Each chart bar shows shows the following attributes of its assigned measured value:

• Alarm HiHi limit

• Alarm Hi limit

• Alarm Lo limit

• Alarm LoLo limit

• Maximum value

• Minimum value

• Setpoint value

  The symbol shows a chart heading and description, descriptions for the horizontal and vertical chart axes, chart bar labels, and numeric measured values.

  

For the sake of simplicity, this procedure shows how to configure a simple chart symbol consisting of only two chart bars. The procedure explains how to set reference values to the symbol's custom properties using substitute references.

Prerequisites

To follow the steps of this procedure, create an ArchestrA object that meet the following requirements:

• Create two ArchestrA user defined objects

  • Create an analog PV field attribute for each object.

  • Enable I/O scaling and clamp the input to the EU range for each PV attribute.

  • Enable limit alarms and set the limits for HiHi, Hi, Lo, and LoLo alarms for each PV attribute.

  • Create an SP analog field attribute for each object.

• Create an InTouch application with a window to verify that the symbol has been configured correctly.

To configure a basic SA_VariableMonitoringBar symbol using ArchestrA attributes

1. Embed the symbol in another symbol in the Industrial Graphic Editor.

2. Select the symbol.

3. In the Wizard options area of the Industrial Graphic Editor, set the NumberOfBars Wizard option to Two.

4. With the symbol selected, press Ctrl + E to show the Substitute Reference dialog box containing a list of the symbol's custom properties.

5. Click Find & Replace.

6. Enter me.Variable1 in the Find What? field.

7. Enter the name of the object you created with the PV attribute in the Replace with field.

   object_name.pv

8. Click Replace All.

9. Find the me.Variable1.SP custom property and remove .pv from the reference value.

   object_name.SP

10. Repeat steps 5-9 for the set of Variable2 custom properties and substitute the name of the second object you created.

11. Save the symbol and check it in.

12. If necessary, deploy the Galaxy containing the object with attributes that are used as reference values of the custom properties.

13. Double-click an instance of InTouch ViewApp to start WindowMaker.

14. Create a new InTouch window and embed the symbol containing the symbol.

15. Run the application in WindowViewer to verify that your basic symbol configuration works correctly.
