1. A system for updating a set of multiple items of information displayable on a client display in order to monitor and control a manufacturing production process, the system comprising:
- a server connected to receive the multiple items of information from a programmable controller or from a diagnostic device in a manufacturing plant and configured to provide the items of information to the client for viewing all of the set of multiple items at one time on the client display;
first mechanisms for defining an information unit for each of the multiple items in the set, assigning to each unit an identifier, managing the identifiers to identify the information units and assigning an update stamp to each identifier;
a data transmission device for receiving new items of information or transmitting the new items of information between the server and the client to provide updated information units on the client display;
second mechanisms for assigning the new items of information, each corresponding to an updated item, to the identifiers and for each new item also assigning a new update stamp indicating that the new item is a more current information unit than an information unit previously assigned to the same identifier; and
third mechanisms for sending an updated information unit to the client to replace an information unit having the same identifier and already used in the display based on whether a new update stamp has been assigned.

Abstract
The invention relates to a system and a method for updating information displayed on a client in a process data-driven environment. An updating stamp is provided along with information units used for displaying process data of automation devices in a browser during collection thereof. The updating stamp is compared with an updating stamp which is managed in a system and is updated whenever new information is added for the respective information unit, the information being updated in the browser if the updating stamps are not identical.

8. A method for displaying and updating multiple items of information relating to control of a manufacturing production process in an industrial plant system for display on at least one client, the method comprising:
-
providing the items of information from a programmable controller or diagnostic device in the plant to make data relevant to control of the manufacturing production process available on a server; displaying the multiple items of information together in a screen view on a client display wherein the individual items of information are separately identifiable and provided in the form of information units such that information units corresponding to different items of information are separately assigned time stamps and are separately updatable; providing identifiers to identify individual ones of the information units; transmitting multiple new items of information from the programmable controller or diagnostic device in the plant, each new item corresponding to an update to an information unit previously assigned a time stamp, to the server or to the at least one client; assigning each of the new items of information to one of the identifiers and assigning to each said new item a updated time stamp which indicates that said new item is an update relative to a previously received and displayed item of information assigned to the same identifier; and determining by comparing values of an updated stamp with a previously assigned time stamp whether any of the items of information has been modified relative to a previously received item. - View Dependent Claims (9, 10, 11, 12, 13, 14)
