RTUs are effectively basic connections between a device and the SCADA system with no internal logic providing the system with I/O capabilities. A single Advanced Computer can represent multiple RTUs as instead I am modeling an RTU as the wired modems connected to that computer rather than the computer itself. Each RTU is referenced separately with an identifier in the modbus communications (see Communications section), so a single computer can distribute instructions to multiple devices. This should save on having a pile of computers everywhere (but if you want to have that, no one's stopping you).
The RTU control code is relatively unique, as instead of having instructions be decoded simply, due to using modbus, I implemented a generalized RTU interface. To fulfill this, each type of I/O operation is linked to a function rather than implementing the logic itself. For example, to connect an input register to a turbine getFlowRate call, the function reference itself is passed to the `connect_input_reg()` function. A call to `read_input_reg()` on that register address will call the `turbine.getFlowRate()` function and return the result.
