Claims (8)

1 . A weather protection cover for a horizontally arranged display unit of a field device of process and automation technology, including: wherein the weather protection cover includes a protective unit, which is arrangeable in such a manner that at least a first section of the protective unit lies opposite the display unit and at least the first section protects the display unit against weather influences, and wherein the weather protection cover includes at least one reflecting component, which is arranged and embodied in such a manner that the at least one reflecting component reflects a display of the display unit, such that the display is observable perpendicularly to the display unit by a user; and wherein the weather protection cover is rotatable about a longitudinal axis of the display unit, wherein the weather protection cover and/or the display unit are embodied in such a manner that a position of the weather protection cover relative to the display unit is determinable, wherein the display unit is embodied to adapt the display, depending on position of the weather protection cover, in such a manner that the display is observable with the help of the at least one reflecting component perpendicularly to the display unit.
2 . The weather protection cover as claimed in claim 1 , wherein the at least one reflecting component includes one planar mirror or two planar mirrors.
3 . The weather protection cover as claimed in claim 2 , wherein the planar mirror is arranged in the first section of the protective unit.
4 . The weather protection cover as claimed in claim 1 , wherein the weather protection cover is rotatable about a longitudinal axis of the display unit, wherein the weather protection cover and/or the display unit are embodied in such a manner that a position of the weather protection cover relative to the display unit is determinable, wherein the display unit is embodied to adapt the display, depending on position of the weather protection cover, in such a manner that the display is observable with the help of the at least one reflecting component ( 5 ) perpendicularly to the display unit ( 2 ).
5 . The weather protection cover as claimed in claim 1 , wherein the display unit is embodied to show a mirror image as the display and/or to rotate the display.
6 . A weather protection cover for a horizontally arranged display unit of a field device of process and automation technology, including: wherein the weather protection cover includes a protective unit, which is arrangeable in such a manner that at least a first section of the protective unit lies opposite the display unit and at least the first section protects the display unit against weather influences, and wherein the weather protection cover includes at least one reflecting component, which is arranged and embodied in such a manner that the at least one reflecting component reflects a display of the display unit, such that the display is observable perpendicularly to the display unit by a user; and wherein the weather protection cover and the display unit include a first reference unit and a second reference unit, wherein the first reference unit is embodied to transmit a signal, wherein the second reference unit is embodied to detect the signal of the first reference unit, wherein based on the signal detected by the second reference unit a position of the weather protection cover relative to the display unit is determinable.
7 . The weather protection cover as claimed in claim 6 , wherein the first reference unit and the second reference unit are embodied to transmit and to detect an optical and/or a magnetic signal.
8 . The weather protection cover as claimed in claim 1 , wherein the weather protection cover is connectable with the display unit and/or the field device and/or a container on which the field device is arranged.

Description

CROSS-REFERENCE TO RELATED APPLICATION The present application is related to and claims the priority benefit of German Patent Application No. 10 2022 107 036.0, filed on Mar. 24, 2022, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to a weather protection cover for a horizontally arranged display unit of a field device of process and automation technology as well as to a field device of process and automation technology. BACKGROUND In automation technology, such as in process automation technology, field devices are often applied, which serve for registering and/or influencing process variables. Serving for registering process variables are sensors, such as, for example, fill level measuring devices, flow measuring devices, pressure- and temperature measuring devices, pH- and redox potential measuring devices, conductivity measuring devices, etc., which register the corresponding process variables, fill level, flow, pressure, temperature, pH value, and conductivity. Serving for influencing process variables are actuators, such as, for example, valves or pumps, via which the flow of a liquid in a pipeline section, or the fill level in a container, can be changed. Referred to as field devices are all devices, which are applied near to a process and which deliver, or process, process relevant information. In connection with the present disclosure, the terminology, field devices, thus, refer also to remote I/Os, power supplies, radio adapters, and, in general, devices, which are arranged at the field level. A field device typically includes a sensor, coming, at least partially, and/or at least at times, in contact with the process, and electronic components, which serve, for example, for signal registration, signal evaluation and/or signal feeding. The electronics of the field device is typically arranged in a housing and has supplementally at least one connecting element for connecting of the electronics to the sensor and/or to an external unit. The connecting element can be any kind of connection. For instance, a wireless connection can be used. The electronics and the sensor of the field device can be embodied as separate units with separate housings or as a shared unit having one housing. Frequently, the field device supplementally includes a display unit, which serves for display of information concerning field device, such as, for example, parameters and/or device status. The display unit can be, for example, a display or a screen. As a rule, settings or calibrations of the field device can be made using the display unit or at least displayed using the display unit, while the settings are then made, for example, using an operating tool. In the case of some field devices, the display unit is, as default, so oriented that the display unit is according to application of the field device horizontally oriented at a measuring point provided for the field device, such that a display on the display unit can only be read from a position above the display unit. For protecting the display unit and the housing of the field device, as a rule, a weather protection cover is provided, which is located above the field device. In the case of a horizontally arranged display unit, the weather protection cover, thus, hides the display unit and, so, gets in the way of the reading of the display. SUMMARY An object of the present disclosure is, consequently, a weather protection cover and a field device, in the case of which a horizontally arranged display unit is readable. As regards the weather protection cover, the object is achieved according to the present disclosure by a weather protection cover for a horizontally arranged display unit of a field device of process and automation technology. The weather protection cover includes a protective unit, which is arrangeable in such a manner that at least a first section of the protective unit lies opposite the display unit and at least the first section protects the display unit against weather influences. The weather protection cover includes at least one reflecting component, which is arranged and embodied in such a manner that the at least one reflecting component reflects a display of the display unit, such that the display is observable perpendicularly to the display unit. The weather protection cover protects the display unit against weather influences, such as rain, thunderstorms, hail and/or solar radiation and enables a reading of the display with the help of the at least one reflecting component. The display is reflected by using the at least one reflecting component from a horizontal plane into a vertical plane, such that the display is observable perpendicularly to the display unit by an observer. The observer can place itself in the horizontal plane alongside the display unit and observe, or read, the display with the help of the redirection brought about by the at least one reflecting component.
