Embodiment Construction

[0026] figure 1 A field device with a human-machine interface 1 is shown. The human machine interface functions to provide an interface between the operator and the equipment. The human-machine interface of the field device of the present disclosure preferably includes a display with a suitable resolution. Suitable resolutions include, but are not limited to, 426x320 pixels, 470x320 pixels, 640x480 pixels, 960x720 pixels. In preferred embodiments, the human-machine interface of the present disclosure includes a monochrome or color display. The display may be a liquid crystal display. The display may also include organic light emitting diodes. The human-machine interface preferably also provides input devices such as, by way of non-limiting examples, keyboards, buttons, touch screens, capacitive touch screens, voice recognition, tracking points, and the like. The HMI also provides memory so that physical layer data can be stored in memory. The human interface may also pro...

Abstract

Field device, in particular a field device of a room automation system or of a power management system or of a hazard detection system, comprising at least one human-machine interface with at least one memory configured to store physical layer data, at least two protocol stacks, wherein the field device is configured to select at least one protocol stack based on the physical layer data stored in the memory of the human-machine interface, wherein the field device further comprises at least two physical layers, at least two pairs, wherein each compatible pair comprises at least one physical layer and at least one protocol stack, wherein the field device further comprises at least one selector switch configured to connect and to disconnect physical layers and protocol stacks, such that a physical layer element and a protocol stack connected or disconnected by the at least one selector switch belong to the same compatible pair.

Description

Background technique [0001] The present disclosure relates to field devices, and in particular to field devices for safety and comfort applications and for power management. This disclosure focuses on the communication functionality of such devices. [0002] Field devices as described in this disclosure may be employed, for example, in room automation or in power management. These field devices can be arranged independently or as an arrangement with several communication units. Modern field devices provide controllers and actuators to manage a wide range of subjects such as heating, ventilation, air conditioning, hazard detection, lighting, fan coils and shutters. [0003] A wide range of communication buses and protocols exist that provide communication functionality between field devices. Typically, wireless solutions such as WLAN, KNX® RF and / or Enocean® are employed. There are also hardwired solutions on the market. These often rely on Ethernet? cables or KNX? cables....
