ABSTRACT:
The invention concerns a controlling and/or monitoring device, comprising a plurality of peripherals (Pa, Pb, Pc, Pn), a central control unit (4) and a communication network (5) connecting the central unit (4) to the various peripherals (Pa, Pb, Pc, Pn). The central control unit (4) comprises one or two transmission controllers (41, 42) connected to the various peripherals through a transmission channel (50), each transmission controller (41, 42) comparing context codes (Ka, Kb, Kc, Kn) received from the peripherals with stored reference codes (Ra, Rb, Rc, Rn) to set a security circuit (6) in a security configuration or in a fault configuration, depending on whether or not the compared codes show identical one-to-one correspondence.
