Embodiment Construction

[0049] In the figures, the same features are marked with the same reference numerals.

[0050] Figure 1a -d shows a field device FG of process automation technology, such as a sensor. In particular, two field devices FG1 and FG2 are shown. Sensors are, for example, pH, redox potential or ISFET, ion-selective, turbidity or oxygen sensors. Other possible sensors are temperature sensors or flow sensors according to the Coriolis principle, the magnetic induction principle, the vortex principle and the ultrasonic principle. Further possible sensors are sensors for fill-level measurement according to the principle of guided and free radiation radar and ultrasound, which is also used for limit level detection, where capacitive methods can also be used for limit level detection.

[0051] Figure 1a and Figure 1d shows the pH sensor, and Figure 1b A fill level sensor according to the radar principle is shown. exist Figure 1c In , a pH sensor is shown on the left and a level s...

Abstract

The present invention provides a method for maintaining at least one field device of a process automation technology. The present disclosure discloses a method for maintaining at least one field device (FG) of process automation technology, comprising the steps of connecting a smart device (SD) to the field device (FG) via a data connection and maintaining the field device (FG) via the smart device (SD).

Description

technical field [0001] The invention relates to a method for maintaining at least one field device of process automation technology. Background technique [0002] Field devices for capturing and / or modifying process variables are frequently used in process automation technology. In general, field devices refer to all devices that are process-oriented and provide or process process-related information. In particular, sensors will be mentioned here, but also actuators. For example, field devices designed as sensors can monitor process measurands such as pressure, temperature, flow, and level or variables such as pH, conductivity, concentrations of certain ions, chemical constituents, and / or concentrations or partial pressures of gases. Measured variable in liquid and / or gas analysis. [0003] In general, measurement transducers - also known as transmitters - are devices that transform an input variable into an output variable according to a fixed relationship. In process a...
