Abstract: A method and a device for exchanging data between a computer and at least one expansion card of an equipment item having a network interface and at least one expansion card is disclosed. The computer and the network interface are connected by a communication network. The network interface and the at least one expansion card are connected to the same industrial bus. After assignment of a virtual network address in the communication network to the at least one expansion card, the network interface is configured with the virtual network address in order to make it possible to identify the network interface in the communication network as representing the at least one expansion card.

Abstract: The invention in particular has as an object a method and a device for exchanging data between a computer and at least one expansion card of an equipment item comprising a network interface and at least one expansion card, the said computer and the said network interface being connected by a communication network, the said network interface and the said at least one expansion card being connected to the same industrial bus. After assignment of a virtual network address in the said communication network to the said at least one expansion card, the said network interface is configured with the said virtual network address in order to make it possible to identify the said network interface in the said communication network as representing the said at least one expansion card.

Abstract: The object of the invention is in particular a method and a device for detecting non-regression of an input/output system from a remote station comprising a test tool adapted for executing a test command of the said input/output system. The said input/output system and remote station are each connected to a communication network. The method comprises transmitting (305), to the said remote station, an instruction to run the said test tool and an instruction to execute the said test command (320), as well as transmitting (315), to a recording device connected to the said communication network, an instruction to record data corresponding to the result of execution of the said command, circulating on the said communication network. After reception, the recorded datum may be analyzed (335) according to a reference datum corresponding to the expected result of execution of the said command.
