ibaQDR generates a product file at the last measuring location. A node in the tree is already prepared for it in the ibaQDR data store configuration.

However, you can also right-click on a measuring location and select Add product file to generate a product file for that measuring location.

ibaQDR supports multiple product files. One or more product files can be added to a measuring location. This can be any measuring location, it does not have to be the last one. However, the last measuring location should contain at least one product file. Only measuring locations in front of the tracking start cannot contain product files.

There is a preconfigured default path for the base directory of the product files: c:\iba\QDR\Product.

If you use multiple QDR data stores then a new sub-folder will be created automatically for each additional QDR data store: c:\iba\QDR2\Product, c:\iba\QDR3\Product etc.

Practical example: Hot rolling mill roughing line

You can set a product file to active or inactive and you can give it a name. This name is used in the data store status window, in validation, and in the log file. This product file name is not the actual name that it will subsequently have in the file system.

You then have to configure the trigger signal that is used to create a product file. The trigger must be a digital signal (digital input signal, digital virtual signal or digital result of an expression). In this case, the product file contains the data between two rising edges of the trigger signal.

The trigger can also be the special signal “Trigger when a tracked part is finished”. In this case, the product file contains the data from the beginning of the entry product to its end.

You can protect the product file by entering a password in the File password field.

The product file node has the same sub-nodes as the normal, time-based ibaPDA data store.

You can use the File node to configure the file name and storage location.

You can use the Info fields node to configure the info fields.

The Cleanup strategy node allows you to configure cleaning up of the product files created.

The last product files are displayed in a separate node in the data store status window. The files can be opened in ibaAnalyzer by double-clicking or using the pop-up menu. The pop-up menu can also be used to open the file storage location in Windows Explorer.

Note on the trigger

Depending on the ibaQDR synchronization status, the trigger results in the following behaviors.

If a trigger occurs while ibaQDR is not fully synchronized, data will be missing at some measuring locations (at the start of the line). If data is missing, these measuring locations have no data in the product file.

The product file then contains the info field $QDR_DataMissing with the value 1.

If ibaQDR is not synchronized, the info field $QDR_NotSynchronized will be written to the product file with the value 1.

In the basic settings for the ibaQDR data store, you can set an option that ibaQDR will only generate product files when it is completely synchronized. See Basic settings for the data store for details.

In this case, all data at all measuring locations should be available (if the length signals are correct). ibaQDR is synchronized when a change of tracking ID (e.g. from ID 1 to ID 2) has been tracked from the tracking start measuring location to the last measuring location (e.g. exit shear).
