Abstract
The invention relates to a method for accessing information and/or services of a distributed automation system comprising a plurality of automation devices, by means of one of the automation devices. According to said method, information concerning an automation device to be serviced constitutes a selection criterion, which can be used to automatically search for information and/or services for servicing the automation device to be served.
Claims7
A method for accessing information and/or services of an automation system comprising:
- providing a plurality of automation devices on a field bus;
- connecting a servicing device to the field bus;
- establishing a communication on the field bus between the servicing device and one of the automation devices;
- retrieving status information from said one of the automation devices into the servicing device via the communication;
- preparing a selection criterion in the servicing device from the retrieved status information:
- and automatically searching by means of the servicing device for information and/or services for servicing said one of the automation devices, using the selection criterion, by searching first in the servicing device, and if not found in the servicing device, searching next among the automation devices on the field bus, and if not found among the automation devices on the field bus, searching next among communications users in a given company network external to the field bus, and if not found in the company network, searching the Internet.
A method for accessing information/or services of an automation system comprising:
- providing a plurality of automation devices interconnected by a field bus;
- connecting a servicing device to the field bus, the servicing device comprising a data storage medium;
- retrieving status information from a given one of the automation devices over the field bus into the servicing device;
- determining a fault or a service requirement of said one of the automation devices from the retrieved status information;
- preparing a search criterion in the servicing device from the retrieved status information and the fault or the service requirement;
- automatically conducting by means of the servicing device, using the search criterion, a first search on the storage device for a software application to resolve the fault or the service requirement;
- if the first search is unsuccessful, next automatically conducting by means of the servicing device a second search via the field bus for the software application among the plurality of automation devices;
- if the second search is unsuccessful, next automatically conducting by means of the servicing device a third search via a communications link for the software application among communication users of a given company on a network external to the automation system;
- and
- if the third search is unsuccessful, next automatically conducting by means of the servicing device a fourth search via the Internet for the software application, the fourth search comprising results prioritized by previously accepted Internet sites, cost, and connection speed.
