Processing received data of the TP
Often there is a situation where the input data obtained from the data source is "raw", that is unprepared or inconvenient for the visual representation, therefore it is necessary to carry out this preparing. In our example, we got the data that comes in code from the scale inside the controller and our task is to make calculation of real values from the obtained data. Data processing in OpenSCADA can be done either directly in the visualisation or in the DAQ-Subsystem. However, mixing the process of the visualisation and processing of the input data confuses the configurations, prevents the history of real data, makes the resulting visualisation shapes less suitable for reuse and increases the load on the visualisation thread, thereby reducing its overall reaction. Accordingly, we will prepare the data in the DAQ-Subsystem.
