Method and system for establishing a communication link between an operating unit and a field device from automation engineering

A method for establishing a communication link between an operating unit and a field device from automation engineering, wherein a frame application and a Bluetooth server are executed on the operating unit, the method comprising:

• connecting the operating unit to a Bluetooth gateway via a radio link and via the Bluetooth server on the basis of a Bluetooth protocol, wherein the Bluetooth gateway is connected to the field device via a communication network;
• establishing and executing a tunnel functionality between the frame application and the Bluetooth gateway;
• sending information about the field device from the Bluetooth gateway to the frame application via the radio link, wherein the information contains identification information of the field device and information about a communication protocol used by the communication network;
• and
• instantiating a device driver for the field device and a communication driver on the basis of the information about the field device, wherein the device driver together with the communication driver are configured to create commands and/or queries to the field device in a format that complies with the communication protocol.

A system, comprising:

• an operating unit, wherein a frame application and a Bluetooth server are executed on the operating unit;
• a Bluetooth gateway;
• and
• a field device from automation engineering, wherein the Bluetooth gateway is connected to the field device via a communication network,
• wherein the system is configured to establish a communication link between the operating unit and the field device by:
• connecting the operating unit to the Bluetooth gateway via a radio link and via the Bluetooth server on the basis of a Bluetooth protocol;
• establishing and executing a tunnel functionality between the frame application and the Bluetooth gateway;
• sending information about the field device from the Bluetooth gateway to the frame application via the radio link, wherein the information contains identification information of the field device and information about a communication protocol used by the communication network;
• and
• instantiating a device driver for the field device and a communication driver on the basis of the information about the field device, wherein the device driver together with the communication driver are configured to create commands and/or queries to the field device in a format that complies with the communication protocol.
