Embodiment Construction

[0037] figure 1 Exemplary process curves are shown for process measurements in an XY graph with arbitrary units. Process measured values ​​are processed cyclically in automation devices. The amount of process measurement values ​​should be thinned out before transmission to the operator station server of the control system, so that each individual process measurement value does not have to be transmitted.

[0038] The method of event-oriented transmission is used according to the prior art, which employs fixedly configured measuring ranges, minimum and maximum transmission rates, and thresholds for hysteresis. in accordance with figure 1 Process measured values ​​are marked with a cross in the process curve of , which were selected by known methods for transmission from the automation system to the operator station server. It can be seen that a good reduction is achieved with a measuring range configured with strong thinning. However, the reproduction of the process curve ...

Abstract

The invention relates to a method for event-oriented transmission of process measurements from at least one measuring device of a control system of a process plant to an operator station server (4) of the control system (3) of the process plant, comprising: a) receiving the process measurements by means of an automation device (9) of the control system (3) of the process plant; b) automatically sensitizing or desensitizing the measurement range of the process measurement values by means of an automation device (9) of a control system (3) of the process plant, automatically reducing the measurement range during sensitization and expanding the measurement range during desensitization by the automation device (9) by means of a heuristic method according to the fact that the transmission rate is lower than the minimum transmission rate of the process measurement value from the measurement device to the automation device (9) or exceeds the maximum transmission rate of the process measurement value from the measurement device to the automation device (9); c) transmitting the process measurement value to an operator station server (4) of a control system (3) of the process plant in an event-oriented manner, the event representing a predetermined change in the process measurement value.

Description

technical field [0001] The invention relates to a method with the features of claim 1 for the event-oriented transmission of process measured values ​​from at least one measuring device of a control system of a process plant to an operator station server of the control system of a process plant. The invention also relates to an automation device according to claim 2 . Furthermore, the invention relates to a control system for a process plant according to claim 3 . Background technique [0002] Process data in process automation is usually relatively "sluggish". Correspondingly, the transfer of process data between automation devices and operator station servers (for operation and monitoring, archiving, etc.) is usually event-driven rather than time (cycle) driven. The aim here is to reduce the throughput, since a large amount of process data (referred to below as “process measured values”) is accumulated especially in process technology plants. [0003] "Thinning" of proc...
