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, once the outside temperature of your facility is 0°C (32°F) or below.

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 Create a new message rule by clicking on the plus-button and/or choose a message rule and click on the puzzle-button.

Example 1: simple message rules without conditions

For this example, we create a message rule that generates a new message whenever the outdoor temperature of your facility is 0°C (32°F) or below. 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.

   

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 reaches 0°C and decreases further on.

You can change these settings anytime. 

Example 2: message rules with conditions

Now, we create similar message rules for the same example. However, this time we'll be using more parameters and a condintion brick. The new parameters are "true" and "false" for rule 1 and "1" and "2" for rule 2. We use them to define even more accurately if a certain situation occured. "1" and "true" always confirm such an occurence and trigger the creation of a fitting message. "0" and "false" confirm, that nothing predefined occured and therefore won't trigger a message.

 You'll need six bricksfor both rules: two result bricks, one brick for conitions with exceptions, 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.

   

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. Add further parameters and connect them
   • You need two "true"-bricks for rule 1. Connect them to the result bricks. Select "false" for the brick, that is connectted to "else".
     
   • You need two bricks for variables for rule 2. Connect them to the result bricks. Select "1" for the brick, that is connectted to "do".

Select "Save" in the lower right corner to save your changes. 

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

You can change these settings anytime.
