AI Technical Summary

Benefits of technology

This technology allows for efficient transmission of comparative values over large amounts of networked storage devices without sending everything up again or having it updated with older versions. It also ensures accurate updates by keeping track of which parts have been changed since last updating them.

Problems solved by technology

Technologies exist today for managing large amounts of data remotely accessible across networks like servers and terminals. However, current methods require complete downloading of full documents containing everything needed, leading to loss of important details due to changing conditions during communication. Additionally, these techniques involve sending requests repeatedly without matching certain aspects of what happened earlier, resulting in losing relevant sections of the downloaded XML pages.

Embodiment Construction

[0033] figure 1 An automation system or a control and control system is shown, for example for controlling and monitoring energy technology installations such as supply networks or electric machines. Furthermore, such control and scheduling systems are used in chemical engineering processes or in automated product manufacturing. in accordance with figure 1 In the control and scheduling system, in the system to be controlled or monitored (in figure 1 (not shown in ) have so-called field devices 2a to 2e; in energy technology installations, these field devices can be, for example, electrical protection devices for monitoring the energy technology installation or electrical dispatching devices for control. The individual field devices 2 a to 2 e are interconnected via a data bus 3 . Furthermore, a server data processing device 4 is also connected to the data bus 3 . The output of the server data processing device 4 is connected to a client data processing device 6 a via a networ

Abstract

The invention relates to a method for matching a data repository of a client data processing device with a source data repository stored in a server data processing device. In order to transfer only a small amount of data, the following steps are carried out: a comparison is sent from the client data processing device (6a) to the server data processing device (4) giving the temporal status of the instantaneous data inventory of the client data processing device (6a) characteristic value (Kv); determine the portion of the source data inventory of the server data processing device (4) that has a higher temporal state than the instantaneous data inventory of the client data processing device (6a) given by the comparison characteristic value (Kv) Later time status; transmit the determined part of the source data inventory to the client computer data processing device (6a); ) is received into the data repository of the client data processing means (6a).
