2.2 Connecting the signals in the algorithm
The input and output signals of the driver must be interconnected with the individual tasks (.mdl files). The individual tasks (QTASK or TASK blocks) are connected to the QTask, Level0,…, Level3 outputs of the main EXEC block.
The inputs and outputs of the OwsDrv driver can be accessed as shown in Fig. 2.2.
The From block allowing the user to read one input signal has the Goto tag set to OWS__temperature. The Goto block allowing the user to set one output signal would have the Goto tag set to OWS__name. The blocks always have the OWS prefix right at the beginning of the tag followed by two _ characters (underscore).
