The system model has to be split off at the interfaces of the test bench. At the splitting (interface) points the blocks of the I/O hardware must be implemented. SCALE-RT includes libraries for the most common I/O hardware components.
The I/O hardware blocks can be found in the SCALE-RT library. The description of the blocks will be shown by right clicking on the blocks and selecting 'Help'.
In addition to the I/O hardware blocks, IN and OUT blocks can be added for the model control during the real-time simulation.
The following figure shows the controller from the previously illustrated system model.
Model prepared for the RT building process
| • | NI DAQ card is included at the interfaces of the controller. Additional IN and OUT blocks are included to have access to the simulation during real-time operation. |
| • | 'IN' Blocks can be used to write down to the target values from the User Interface. |
| • | 'OUT' Blocks are used for monitoring and data logging. |
| • | Only 'IN' and 'OUT' Blocks located in the top level can be accessed during real-time operation. |
Tip: Use gains to scale the output of the I/O Hardware to your model units.
