Method and device for adjusting signalling of a field device

A method for adapting a signaling of a field device displayable via a signal display of the field device, the method comprising:

• specifying, with a user device, a color tone of at least one display element of the signal display of the field device, wherein the specifying of the color tone comprises:
• capturing, using a camera of the operating device, an image of a signal displayed via the signal display of the field device or an image of at least a part of the field device;
• and
• determining, using the operating device, the color tone of the at least one display element of the signal display based on an analysis of the image;
• associating, with the user device, an attribute of the color tone of the at least one display element of the signal display, the attribute representing a meaning of the color tone for indicating a state of the field device;
• transmitting a control signal from the user device to the field device, the control signal containing information relating to the color tone and relating to the attribute associated with the color tone;
• storing the color tone and the attribute assigned to the color tone in a memory of the field device;
• and
• activating, on the field device, the color tone of the at least one display element of the signal display and the attribute assigned to the color tone based on the control signal so that, when the state of the field device occurs, the color tone is displayed via the signal display of the field device as signaling.
