Embodiment Construction

[0030] figure 1A device A of automation technology is schematically depicted. In the device, a process engineering process is run in which at least one product of predetermined quality and quantity is determined from at least one predetermined quality and quantity of raw material. For example, the device has a tank and a line draining from the tank. In order to measure the fill level of the tank as a process variable, a sensor unit SE1 , for example a sensor unit SE1 operating according to the radar principle, is attached to the tank. For measuring the flow velocity in the pipeline, a sensor unit SE2 is used which determines the flow velocity of the process variable of the medium flowing through the pipeline according to the Coriolis principle. Furthermore, an actuator unit AE1 is mounted on the tank, which actuator unit AE1 is for example a pump and delivers the medium into the tank at an adjustable rate as a control variable.

[0031] The sensor units SE1 , SE2 and the ac...

Abstract

The invention relates to a method for monitoring a device of automation technology. In the device, a sensor unit and a actuator unit communicate with a superior unit via a communication network; the sensor unit sends the process value and the state data to a superior unit; the actuator unit transmits the control variable and the state data to the superior unit; and the superior unit sends the operation telegram to the sensor unit and the actuator unit. The process comprises the following steps: enabling a field detection unit to acquire and store all data which is transmitted through a communication network and consists of a process value, a control variable, state data and the operation telegram, and providing timestamps for the data and the operation telegram; temporarily distributing the operation telegram to the data; and analyzing the assignment and creating an intervention system containing the device status created on the basis of the transmitted data from the sensor unit and from the actuator unit, and intervention consisting of at least one operating telegram following the transmitted data from the sensor unit and from the actuator unit.

Description

technical field [0001] The invention relates to a method for monitoring a plant in automation technology, in which at least one sensor unit and at least one actuator unit and a field detection unit are used in the plant, wherein the sensor unit and the actuator unit communicate with a superordinate via a communication network The unit communicates, where the sensor unit sends process values ​​and status data to the superordinate unit, where the actuator unit sends control variables and status data to the superordinate unit, and where the superordinate unit sends operational telegrams to the sensor unit and actuator unit . Background technique [0002] Field devices for industrial installations are already known from the prior art. Field devices are frequently used in process automation as well as in manufacturing automation. In general, field devices refer to all devices that are process-oriented and supply or process process-related information. Accordingly, field device...
