Central nodes and terminal self-configuring instrumentation and secure automation system.

摘要

terminal node instrumentation (2): # - connecting means (30, 31, 35) for coupling with an external device (10) for generating an electrical actuating signal, communication means (28, 29) to receive or send messages, # - means for encrypting messages sending generated and decrypt messages received, # - storage means (33) for storing keys for encryption and decryption of messages and information on the operation of the own node (2) , on states of the network devices (4, 5, 9, 10) and associations between states, # - processing means (34) to update information storage means (33) according to received messages and identify events defined by state changes occurred in devices (4, 5, 9, 10), to generate messages for sending as these events and control the generation of electrical signals in the connection means (30, 31, 35) .
