Configuring Lines¶

User interface¶

In “Machines and Lines”, you can perform the following actions:

① Navigates to the “Configuration” tab
② Adds a new “Line”
③ Edits the existing “Line”
④ Deletes the existing “Line”
⑤ Displays the current step
⑥ Navigates to the previous step

Procedure¶

To add a new line and the corresponding machines, proceed as follows:

1. From the navigation tab, click “Configuration” and select “Machines & Lines”.
2. In “Manage Lines”, click “Add Line”.
   The following window appears:
3. Click “Select Asset”.
   The following window appears:
4. Select the desired “Asset” from the list and click “Select” to auto-fill the asset parameters.
   The following window appears:
5. Using the “Calendar” dropdown option, select the calendar that you have instantiated earlier. Every created calendar will appear here. If the dropdown list is empty, create a calendar before it can be assigned to the line.
6. Click the “OEE Setup” tab to configure and enable the OEE calculation for the line.
   The following window appears:
7. In the “KPI Targets” area, you can modify the bandwidth for Error, Warning and Success displayed through the colors Red, Yellow, and Green in the gauges. It helps you to identify if you are currently reaching your targets or not. For this, fill in the table in the following way:
   In the example above, two limits for Warning and Error are defined. The bandwidth for Success follows accordingly. In this example it works following in the following way:
   
   • OEE Warning: 70%
     
   • OEE Error: 60%
     The two values given in the configuration always describe the upper levels. Therefore, in the OEE gauge it will display the following colors for the following bandwidths:
     
   • Red: 0 - 60
     
   • Yellow: 61 - 70
     
   • Green: 71-100
     The gauges for Availability, Performance, and Quality follow the same approach.
8. Perform variable mapping. It has two steps, Operand Mapping and Source Mapping. Each step is described in detail later in this chapter.

If OEE needs to be calculated on a line level, five out of the following six variables must be specified for the line:

The following logic applies to the three Quality KPI relevant variables - good parts, rejected parts, and total parts. You need to map two out of three variables, two data points from the asset model and the third one can be calculated through the auxiliary expression which you need to select in that step.

Refer to Section Configuring KPIs to learn about the auxiliary expressions for the Good Parts, Rejected Parts, and Total Parts.

Operand Mapping¶

In the Operand Mapping, you map the counter variables for the quality KPI calculation - Good Parts, Rejected Parts, and Total Parts.

For each of them, a type needs to be selected. Following are the three different types available:

• Difference Counter: The machine sends a counter value of the pieces, that were produced since the last time a counter value was sent to Insights Hub. In the picture below you can see that the value for the counter ranges between 20 and 24, this means that each time a counter value was sent to Insights Hub, 20 to 24 pieces were produced".
  

• Absolute Counter: An absolute counter continuously counts up and is reset to 0 from time to time, for example, after a shift. In the picture below, you can see a typical absolute counter.
  

• Calculated - This variable will be calculated through the defined auxiliary KPI e.g. total parts = good parts + rejected parts

In the following scenario, good parts and rejected parts are measured through variables as difference counters, while the total parts are calculated through the auxiliary expression. To map these variables, proceed as follows:

1. Select the Type “Difference counter” using the radio button for the Good Parts.
2. Click the Pen icon on the right side to open the Asset / Aspect selector.
   The following window appears:
   By default, “Filling Line” asset is selected as shown in the above image and the selection is also highlighted. The selected assets affects the variables and aspects listed under "Available aspects and variables".
3. Click the icon next to the variable of your choice.
   "Your selection" section displays the selected asset, aspect, and variable.
   In this example, the selected asset is “Filling Line”, the aspect is “Machine Values” and the selected variable is “GoodProducts”. Additionally, you can also select a default quality code definition or a custom quality code definition, which was created before. By default, the “OPC UA and S7” option will be selected. If the datapoint has no quality code attached, this selection does not have an influence on the datapoint collection. Only if the selected variable also uses quality codes, these will be evaluated by Insights Hub OEE. To learn more about quality codes, for more information, refer to Configuring Quality Codes.
4. Once the selection is done, click “Select”.
5. For Rejected Parts, follow steps 1 to 4 again.

6. For measuring the "Total Parts", proceed as follows:

   a. Select the Type “Calculated” using the radio button.
   This action populates a dropdown field “Select Auxiliary Expression”:
   
   b. Select “Total Parts” from the dropdown.

The following screen shows the completed Operand Mapping:

Next step in the configuration is Source Mapping.

Source Mapping¶

The Source Mapping follows a similar approach compared to Operand Mapping.

In this step, you define under which variables the order, product, and status information can be found. To achieve this, proceed as follows:

1. Click the Pen icon on the right side to map the Order information.
   The following Asset / Aspect selector window appears: By default, “Filling Line” asset is selected as shown in the above image and the selection is also highlighted. The selected assets affects the variables and aspects listed under "Available aspects and variables".
2. Click the icon next to the variable of your choice.
   "Your selection" section displays the selected asset , aspect, and variable.
   In this example, the selected asset is “Filling Line”, the aspect is “Machine Values” and the selected variable is “GoodProducts”. Additionally, you can also select a default quality code definition or a custom qualtiy code definition, which was created before. By default, the “OPC UA and S7” option will be selected. If the datapoint has no quality code attached, this selection does not have an influence on the datapoint collection. Only if the selected variable also uses quality codes, these will be evaluated by Insights Hub OEE. To learn more about quality codes, for more information, refer to Configuring Quality Codes.
3. Once the selection is done, click “Select” and the window will get closed.
4. For Products, follow steps 1 to 4 again and select the proper variable for the product information.
5. For Status Mapping, select the applicable Status Mapping from the dropdown “Select Status Mapping”.
   It is recommended to create a Status Mapping in advance. For more information on this topic, refer to Section Configuring Status Mapping.
6. Once the applicable status mapping selection for the line asset is done, select the variable where to find the status information. This follows the same process as the order and product information.

The following screen shows the completed Source Mapping:
