• central (network) - to control the execution units with the exchange of information with the central point of protection and control, management system by the operator on duty;
• universal, including function as autonomous, so and network systems, operating in a network mode under the leadership of central control and turning into an autonomous mode in the event of failures in network equipment or a central device.

Generalized block diagram of all the above SKD is the same and includes the following components:

• device identification;
• controller;
• execution unit.
