Method for non-visual optical transfer of data by field device e.g. level measuring device, involves transferring a temporary non-visual optical signal for the transfer of data by field device

摘要

The method involves providing a field device (FG) with a display element (D). A temporary non-visual optical signal (O2) is transferred for the transfer of data by the field device. The field device information is transmitted in digital form through the non-visual optical signal. An optical light source is provided for generating the non-visual optical signal. An independent claim is included for a field device.
