Teco_Databox is a project designed to demonstrate how to transfer data from/to the Databox memory of the Teco device. Via the Device Manager, the Tecomat1 device of type Teco and its IP address are defined. On the Databox page, the Enable reading/writing Databox option is active and the links to the respective tags defined within the System device are specified. The following tags are defined within the System device: The Control of type Byte tag is used to control the data transfer from/to the databox (0 – ready, 1 – read, 2 – write). The Status tag of type LongInt is connected to the Active Text component placed in the visualization window and indicates the activity that is being performed with the databox (Ready/Reading/Reading completed/Read error/Writing/Writing completed/Write error). The DataLength and DataOffset tags are used to define the range of data to be transferred from/to the databox. The current data range is accessed via the DataBuffer tag of type Array of Byte.

The visualization window contains a Data Grid component (Databox data) that displays the values of the DataBuffer tag and the corresponding index of the data in the databox (the IndexArray tag). The latter tag is automatically updated in the InitIndexArray script every time the databox is accessed (read or written).
