Configure Information Categories

The purpose of this instruction is to present how to configure calculation of Information Categories on the basis of specific rules.

To accomplish this task, we have to take some basic steps, including

1. create an entry point set, which groups the rules by which information categories are determined;
2. assign this entry point set to a controller;
3. create calculation rules, which will be contained in the entry point set.

The calculation rules define into which information category a wind turbine may fall at the certain time period based on the currently active status code.

Information categories are used to define the turbine state, e.g. full performance, partial performance, forced outage. There are 4 levels of information categories, which are standard and cannot be changed. Only on level 5 a user can add specific information categories of lower level to make calculation of information category more detail..

Availability Configurator plug-in is required for performing the following configuration. For more detail information, refer to Configuring Plug-ins.

Let's start the process of configuring the calculation with creating an entry point set. To do this, please, follow the steps below:

• in the Configuration section of the Availability Configurator toolbar click ;
• in the New section of the Availability Configurator toolbar click ;
• let's name it Entry Point Set 01;

• apply the changes by clicking in the upper left corner.

Now we need to assign a recently created entry point set Entry Point Set 01 to the controller Unit 01 in the following way:

• select Controller Configuration window in the main presentation area and select Unit 01 in the Controller View window;
• expand the nodes Model -> FWProject -> FWRevision -> Information Categories and in the EntryPointSet drop-down list select Entry Point Set 01;
• click OK to proceed.

The next step is to create the calculation rules, which Entry Point Set 01 will contain. Let's create rule named Electrical Error, which will be defined by status code 41 in the following way:

• select Information Category Configuration window in the main presentation area and click Entry Point Set 01 in the Entry Point Set window to the right;
• right click in the Entry Point Rules area at the bottom and select Entry Point Rule;
• in the Entry Point Rule Configuration window type Electrical Error in the Name field;
• click the Information Category drop-down arrow, expand node Level:4 and select OUT OF ELECTRICAL SPECIFICATION;
• click OK to proceed;

• click the Rule drop-down arrow and enter status code 41in the empty field. This means, that if status code 41 is activated, the turbine state will be determined by the OUT OF ELECTRICAL SPECIFICATION information category;
• click OK to proceed.

After creating the rule, it appears in the Entry Point Rules area with the information on name, status code and assigned information category.

You can also calculate the Information Categories automatically by following the steps described in Calculate Information Categories Automatically.

The next manual section Configure Availability will provide you with the instructions on how to configure calculation of the Availability.
