Embodiment Construction

[0028] figure 1 Two exemplary field devices are shown connected to a fieldbus 1 with physical interfaces 2 and electrical energy storage means 3 . The field device also includes a sensing module 4 and a wireless transceiver module 5 .

[0029] The physical interface 2 is connected to the fieldbus, receives and sends control data, and also draws power from the fieldbus. Energy is stored in an electrical energy storage component 3, which may be a capacitor, battery or the like. The sensing module 4 implements one or more functions of the field device on the industrial process. Examples of field device functions are measuring process variables, controlling processes, and process flows. The wireless module 5 obtains electric energy from the electric energy storage component, and sends out wireless signals. The signal is sent out in a discontinuous mode with power cycling of the wireless module 5 .

[0030] figure 2 One embodiment of the invention with a wireless module and ...

Abstract

An industrial control system with a plurality of industrial field devices for controlling and monitoring an industrial process and each industrial field device is having first control functions and at least one industrial field device is having second control functions.

Description

technical field [0001] The present invention relates to industrial control systems and industrial field devices in industrial control systems for monitoring and / or controlling industrial processes. The present invention provides wireless communication of a second signal to / from an industrial field device. Background technique [0002] In industrial plants, control systems are used to control a number of industrial processes taking place in the plant. Typically, a plant has a central control room containing a computer system with user I / O, disk I / O, and other peripherals known in the computing art. A controller and a processing I / O subsystem are coupled to the computing system. The process I / O subsystem includes a plurality of I / O ports that connect to various field devices throughout the plant. Field devices known in the field of control include various analytical devices, pressure sensors, capacitive pressure sensors, resistance temperature detectors, power switches, the...
