Systems distribution

Control systems are divided by function into three groups. These are the groups:

- logical systems,
- digital systems,
- hybrid systems.

## Logical Systems

Logical systems are systems that interact with their environment using two-valued elements (yes, no, or 1.0, etc.) these systems process information according to the rules of Boolean algebra and are therefore also called Boolean or binary systems. Binary system can be implemented either a contacting or non-contacting switch.

## Digital Systems

Digital systems are systems which work with arithmetic operations and are controled by algebraic rules. In particular, the basic algebraic operations of addition, subtraction, multiplication and division, but it is not excluded or the use of more complex operations or functions. Digital system is based on a microprocessor.

## Hybrid systems

Combining logical and numerical operations in one system is a hybrid system.

Control systems are also divided according to the method of information processing in the two groups. These are the groups:

- combinational control
- sequential control

## Combination control

When the combination reacts driven control system as a combinational logic circuit, i.e. the value of the output depends only on the combination of input values.

## Sequence control

Sequence control unit controls the system depending on the time or the state of the controlled process. Alternatively, it is possible to combine both functions.
