```
 abstract RegisterBlock getRegisters(Address firstRegister, Integer count)
```
    Retrieve a block of 16 bit registers (Input Registers and Holding Registers).
    
    Parameters:
    
    firstRegister - The first modbus register that is desired in the output.
    
    count - The maximum number of registers to retrieve ( >= 1 ).
    
    Returns:
    
    A RegisterBlock with of all the retrieved values
  - getDiscretes
```
 DiscreteBlock getDiscretes(Address firstDiscrete, Integer count)
```
    Retrieve a block of 1 bit values (Coils and Discrete Inputs).
    
    Parameters:
    
    firstDiscrete - The first modbus discrete value that is desired in the output.
    
    count - The maximum number of values to retrieve ( >= 1 ).
    
    Returns:
    
    A DiscreteBlock with of all the retrieved values
