A method for remotely controlling installations through a data processing network. Comprising appliances such as measuring instruments and actuating devices. The method provides prearranging a server (2) wherein a gateway is resident, the gateway being connected to a first port that has a public static IP address and that can be seen within the network (1), associating peripheral devices (4) to respective appliances (6b) and supervision units (3) to each user of the control. Each terminal, i.e. a peripheral device (4) and/or a supervision unit (3), requires and obtains a dynamic IP address (40) and is granted to access network (1) by a IAP. Then, a request of a connection to the gateway of server (2) is carried out by the terminal through the first port. The connection is accepted by the gateway of server (2), which stores the IP address (40) of the terminal. Afterwards, the gateway asks and obtains from the terminal a proper identification code (44), and stores terminal IP address (40) and identification code (44) in a record of a table of correspondence (15). |
