An automation system made through a communication network and including: a first and second programmable logic controller respectively executing first and second automation applications to respectively control first and second sets of associated input/output modules; a third programmable logic controller, including a storage storing the first and second automation applications and configured to execute the first automation application to stand in for the first programmable logic controller, or to execute the second automation application to stand in for the second programmable logic controller.

Automation system

A method of managing an electronic microcontroller system, the microcontroller system including: two processors with a first processor configured for execution of a nonsecure application exhibiting a nonguaranteed level of functional security and integrity, and a second processor dedicated to execution of a secure application implementing code and data, and involving a guaranteed level of functional security and integrity, the secure application to implement a security function; and a mechanism to access to a shared memory space. The first processor includes a unit for managing the memory configured to implement a write access control, to manage write access to the shared memory space, that is not modifiable when the secure application implements its security function.

Method of secure management of a memory space for microcontroller

The invention relates to an input module () for a programmable logic controller able to be connected to a plurality of elements of an automated chain, the module () comprising:

Input module for programmable logic controller

An overvoltage protection device that can be adapted to a programmable automaton power supply, including: a first detection and protection device configured to detect a possible overvoltage at a first point of a primary or secondary circuit, and including a mechanism triggering a short-circuit if an overvoltage is detected at the first point such as to stop all energy transfer toward the output of said power supply; and a second detection and protection device configured to detect a possible overvoltage at a second point of the primary or secondary circuit, and including a mechanism triggering a short-circuit if an overvoltage is detected at the second point such as to stop all energy transfer toward the output of said power supply; and a thyristor having an independent power supply and configured to maintain, by memory effect, the short-circuit that may have occurred.

Device for protecting against overvoltage for automaton power supply

A device for controlling point-to-point communication between a module and a transmission bus, the device including a printed circuit that carries the transmission bus and that includes a connection element to connect the module to the transmission bus. The printed circuit includes a communication control unit disposed between the transmission bus and the connection element, the communication control unit includes unidirectional communication logic gates, and a logic control circuit for the logic gates. Such a device may, as an example, find application to programmable controllers.

Device for controlling point-to-point communication between a module and transmission bus

This invention is a system for remotely loading and remotely maintaining an electronic card () belonging to automation equipment and comprising a minimum of a processing unit (), an internal bus () and a resources controller () which has one or more JTAG interface registers () accessible for reading/writing by a JTAG server () that is external to the automation equipment. The resources controller () contains a status engine () capable of interpreting and carrying out instructions stored in one or more of the JTAG interface registers () and able to use the resources () managed by the resources controller () and shared with the processing unit (), without the intervention of the processing unit ().
