Message rules define, if and when messages are generated. 

You can describe those rules with the help of QUDE (QBRX universal data point editor) QUDE is a versatile tool for the creation of various evaluation rules. There are almost no restriction for the creation of new rules.

In this article, we'll be talking about the creation of a new message rule in QUDE. As an example, we define a rule that warns us, when once the outside temperature of your facility is below reaches 0°C (32°F).

Opening QUDE

Before working with QUDE, you have to open the tool. Go to the message board of your designated facility and select the gear wheel-button on the right side. You are send to the message rule board. Choose a message rule and click on the puzzle-button.

Example: Outdoor temperature

reaches 0°C

For this example, we create a message rule that generates a new message whenever the outdoor temperature of your facility is below reaches 0°C (32°F). The freezing point is relevant for various situations and the evaluation rule only consists of a few bricks. 

 You'll need four bricks: one evaluation, one for comparisons, one for numeric data points and a constant.

1. Drag bricks into the editing field 
   • Drag all of the mentioned bricks to the editing field in QUDE. 
2. Combine bricks
   • Combine the bricks until they look like the picture below.
   • Connect the result brick to the brick for comparisons. There are two empty areas inside the comparison brick. Link the brick for numeric data points to the left area and the constant brick to the right area.

   

3. Search, choose and select a numeric data point
   • Next to the editing field, you can search data points in the upper search bar. For our example, we'll be looking for "outdoor temperature". You can only find data points that belong to your chosen facility and its sub-facilities. 
   • Select the right data point. It's now displayed below the search bar and can be used in bricks. 
   • In the brick for numeric data points, you can now choose "outdoor temperature" instead of "undefined".
4. Choose the constant
   • In this case, the constant stands for the temperature. That's why we define it as "0" for "0°C (or 32 for 32°F).
5. Choose a comparison
   • Change the sign for "=" to "≤" simply be clicking on it and selecting the right symbol.
6. Save your settings
   • Select "Save" in the lower right corner to save your changes. 

From now on, a message is generated whenever the outdoor temperature is below reaches 0°C.

You can change these settings anytime.
