摘要： A valve system includes a valve, which is operated by a pneumatic actuator and forms part of an industrial plant, wherein the valve system includes a diagnostic system that includes either a pressure detection unit for acquiring data on a pressure variation in the pneumatic actuator and/or at least one acoustic detection unit for detecting an acoustic variation in the valve system, where the valve system additionally includes a pilot valve, preferably a solenoid valve, which controls the pneumatic actuator, an electrical connection to an electrical power supply network supplying the pilot valve to supply electrical power to either the pressure detection unit and/or the acoustic detection unit, and where the diagnostic system additionally includes a measurement unit for identifying changes in the electrical power supply network for the pilot valve to identify a starting point of a closing or opening action of the valve.

摘要： Method for producing a bidirectional connection between a device forming a field device and an application in a central facility, wherein a bidirectional connection is produced between the device that forms the field device and the application in a central facility, where a bridge function running on a mobile communication terminal establishes a short-range radio connection with the device, establishes a long-range radio connection with the application in the central facility and establishes a data channel for bidirectional communication between the application in the central facility via the long-range radio connection and the device via the short-range radio interface.
