Weight based visual communication of items representing process control objects in a process control system
First Claim
1. A method for communicating items representing process control objects in the form of field devices to a user of a wireless terminal with a display screen in a computerized process control system for controlling an industrial process, where each of the items is a data item that is a reference to other data about a corresponding, different process control object, the method being performed in an item communication control unit of an item communication arrangement and comprising:
- continuously determining weights of the items, anddisplaying the items with the highest weights to the user via the wireless terminal that fit in the display screen and in an order defined by the weights of the items,wherein the weight of an item is determined based on an item selection pattern of the user and comprises a position weight factor based on the position of the corresponding process control object and the position of the user, where the position weight factor decreases with increasing distance between the process control object and the user,wherein the weight of said item reflects a predicted use of the item based on the item selection pattern of the user, andwherein the pattern is a pattern of usage over time of the item comprising intervals of frequent use separated by intervals of infrequent use, and the weight comprises a first weight factor, the method further comprising predicting if the use of the item at a current point in time is in the interval of infrequent use or the interval of frequent use and assigning a first value to the first weight factor in case the interval is the interval of infrequent use and a second value in case the interval is the interval of frequent use, where the second value is higher than the first value.

Abstract
A method, item communication arrangement and a computer program product communicate items representing process control objects to a user of a wireless terminal in a process control system. The arrangement includes an item communication control unit providing the items representing process control objects and configured to continuously determine weights of the items and visually communicate items to the user via the wireless terminal in an order defined by the weights of the items. The weight of an item is determined based on an item selection pattern of the user.

7. An item communication system for communicating items representing process control objects in the form of field devices to a user of a wireless terminal with a display screen in a computerized process control system for controlling an industrial process, where each of the items is a data item that is a reference to other data about a corresponding, different process control object, the item communication system comprising:
-
an item communication control unit providing said items representing the process control objects and configured to continuously determine weights of the items, and display the items with the highest weights to the user via the wireless terminal that fit in the display screen and in an order defined by the weights of the items, wherein the weight of an item is determined based on an item selection pattern of the user and comprises a position weight factor based on the position of the corresponding process control object and the position of the user, where the position weight factor decreases with increasing distance between the process control object and the user, wherein the weight of said item reflects a predicted use of the item based on the item selection pattern, and wherein the pattern is a pattern of usage over time of the item comprising intervals of frequent use separated by intervals of infrequent use, and the weight comprises a first weight factor, the an item communication control unit being further configured to predict if the use of the item at a current point in time is in the interval of infrequent use or the interval of frequent use and assigning a first value to the first weight factor in case the interval is the interval of infrequent use and a second value in case the interval is the interval of frequent use, where the second value is higher than the first value. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A computer program product for communicating items representing process control objects in the form of field devices to a user of a wireless terminal with a display screen in a computerized process control system for controlling an industrial process, where each of the items is a data item that is a reference to other data about a corresponding, different process control object, said computer program product being provided on a non-transitory data carrier comprising computer program code configured to cause an item communication system to, when said computer program code is loaded into at least one device providing the item communication system,
continuously determine weights of the items, and display the items with the highest weights to the user via the wireless terminal that fit in the display screen and in an order defined by the weights of the items, wherein the weight of an item is determined based on an item selection pattern of the user and comprises a position weight factor based on the position of the corresponding process control object and the position of the user, where the position weight factor decreases with increasing distance between the process control object and the user, wherein the weight of said item reflects a predicted use of the item based on the item selection pattern of the user, and wherein the pattern is a pattern of usage over time of the item comprising intervals of frequent use separated by intervals of infrequent use, and the weight comprises a first weight factor, the computer program code being further configured to predict if the use of the item at a current point in time is in the interval of infrequent use or the interval of frequent use and assigning a first value to the first weight factor in case the interval is the interval of infrequent use and a second value in case the interval is the interval of frequent use, where the second value is higher than the first value.
