Field Device and Method for Parameterizing the Field Device

A method for parameterizing a field device with at least one parameter, the at least one parameter being input into the field device via an operating unit or transferred to the field device via a first logical interface and deposited in a memory of the field device, the field device calculating, based on at least the deposited at least one parameter and a device ID of the field device, a first checking characteristic, the first checking characteristic being also deposited in the memory and transferred via a second logical interface to an engineering system and output on a display, the method comprising:

• transferring, by the field device, the at least one parameter via a third logical interface which is data-diverse with respect to the first interface to the engineering system and outputting said at least one parameter on the display;
• transferring, by the field device, the device ID to the engineering system and outputting said device ID on the display;
• transferring to the field device a first checking characteristic input by a user after visual checking the at least one parameter and the device ID on the engineering system in a predefined format via a fourth interface which is data-diverse with respect to the second interface;
• and
• comparing, by the field device, the received first checking characteristic to the calculated first checking characteristic to validate the at least one parameter.

A field device for parameterizing the field device with at least one parameter, the field device comprising:

• a computing unit;
• and
• memory;
• wherein the field device is configured to:
• receive at least one parameter via a first logical interface and deposit said received at least one parameter in the memory;
• calculate, based on the deposited at least one parameter and a device ID of the field device, a first checking characteristic;
• deposit the calculated first checking characteristic in said memory;
• transfer said calculated first checking characteristic via a second logical interface to an engineering system for output on a display;
• wherein the field device is further configured to:
• transfer the at least one parameter via a third logical interface which is data-diverse with respect to the first logical interface to the engineering system for output of at least one parameter on the display;
• transfer the device ID to the engineering system;
• receive a first checking characteristic on the engineering system input in a predefined format via a fourth interface which is data-diverse to the second interface;
• and
• compare the received first checking characteristic to the calculated first checking characteristic to validation of the at least one parameter.
