Method for Configuring Field Devices
First Claim
1. A method for configuring field devices in a process automation system, in which the field devices are connected to other automation components via a fieldbus, which makes use of a configuration tool,whereina copy of the current configuration of each field device is stored in the configuration tool in a once-only step,and the following steps are repeated recursively:
- a. storing the new configuration in the field device and assigning a unique, structured version ID,b. transferring the version ID into the configuration tool,c. using the structure of the version ID to determine the difference between the copy stored in the configuration tool and the new configuration of the same field device, andd. retrieving from the respective field device the determined difference for updating the configuration data and parameter data in the configuration tool.

Abstract
A method is disclosed for configuring field devices in a process automation system in which the field devices are connected to other automation components via a field bus. In order to minimize the load on the field bus, the actual configuration of each field device is stored as a copy in a configuration tool, and each change in the configuration initiated on the field device is stored with an unambiguous, structured version ID. In order to update the configuration data and parameter data in the configuration tool, the version ID is transferred into the configuration tool, and the difference between the copy stored in the configuration tool and the new configuration is determined from the structure of said version ID. The difference is retrieved from the respective field device in order to update the configuration data and parameter data in the configuration tool.

5. A method for configuring at least one field device, each field device having a respective configuration stored in a configuration tool, comprising:
-
a. storing a new configuration in the at least one field device and assigning a unique, version ID, b. transferring the version ID into the configuration tool, c. determine a difference between the respective configuration stored in the configuration tool and the new configuration of the at least one field device based on the version ID, and d. retrieving from the at least one field device the determined difference for updating configuration data and parameter data in the configuration tool.
