A method and device for connecting electrical and electronic devices into integrated network. The device includes monofunctional computer, i.e. programmable controller and actuator controller, and two information channels or networks. Via the inner network takes place the exchange of information between the programmable controller and the actuator controller. Inner network can be: alternate current electricity network, separate low voltage cable network, radio communication network. Public internet, via which are changed system parameters of the programmable controller via WEB interface and secured information on the object for the system operator. Via the internet into the programmable controller are downloaded software updates from the software service server of the operator and software modules of the new applications of the controller of the effective device. Updating of the nodes and controlling elements of the device are done in real-time.
