Introduction

This tutorial will take you through the steps to create a simple SCADA or HMI graphic page similar to this:

Example graphic page

The tutorial is structured in 8 parts:

  1. Create the folder to work in
  2. Create the tags
  3. Obtain the graphic symbols
  4. Add and configure the tank symbol
  5. Add and configure the valve symbols
  6. Add and configure the pump symbols
  7. Add dynamic text
  8. Test the graphic page

Part 1: Create the folder to work in

A. Create a new Folder:

  1. In the Tag Window select the root folder (or a suitable destination folder).
  2. Right-click and select Add new folder.
  3. Enter a suitable name, for example: Simple Process.
  4. Press return to complete the rename of the folder from its default name to your chosen name.

Part 2: Create the tags

Add the tank level data source tag:

  1. Select the folder Simple Process you created in part 1.
  2. Right-click and select Add new tag, followed by Random, followed by Random Analog Data Point Tag.
  3. Enter the name Tank Level, and press Return to confirm the change of name.
  4. In the Properties Window, enter these properties:

    PropertyValue
    MaxScale8
    HistoricEnableTrue
    HistoricSignificantChange0.1
    NominalRange4
    NominalValue4
    StepValue0.5

B. Add the pump state tags:

  1. Select the folder Simple Process you created in part 1.
  2. Right-click and select Add new tag, followed by Random, followed by Random Digital Data Point Tag.
  3. Enter the name Pump 1, and press Return to confirm the change of name.
  4. In the Properties Window, enter these properties:

    PropertyValue
    EventSeverity200
    TextState0Stopped
    TextState1Running
    ChangeProbability0.25

    Setting EventSeverity to 200 ensures the digital state changes are recorded in the Event Log.

  5. Repeat steps 1 to 4 to create a second pump state tag called Pump 2.

C. Add a temperature tag:

  1. Select the folder Simple Process you created in part 1.
  2. Right-click and select Add new tag, followed by Random, followed by Random Analog Data Point Tag.

  4. In the Properties Window, enter these properties:

    PropertyValue
    MaxScale100
    MinScale0
    Units°C
    HistoricEnableTrue
    HistoricSignificantChange0.1
    NominalRange5.0
    NominalValue37.0
    StepValue0.2

    Note: To enter the ° (degree) character in the Units field, hold the ALT key down and enter 248 on the numeric keypad. The ° (degree) character will appear when you release the ALT key.

D. Add the graphic page tag:

  1. Select the folder Simple Process you created in part 1.
  2. Right-click and select Add new tag, followed by Core, followed by Graphic.
