Abstract

A method for operating at least one optoelectronic button or operating element arranged behind an optically transparent control panel of a field device of automation technology for detecting an actuation of the optoelectronic button or operating element by an operator of the field device includes detecting whether the field device of automation technology is located in an interior area or in an exterior area; defining an evaluation condition which is used to detect the actuation of the optical button or control element; and detecting or evaluating whether an actuation of the optoelectronic button or control element is present based on the defined evaluation condition.
