Embodiment Construction

[0040] figure 1 A schematic block diagram of the automated system is shown. Those skilled in the art understand that the automation system shown is only exemplary and that all elements, modules, components, user devices and units belonging to the automation system can be configured differently and still achieve the basic functions described here.

[0041] figure 1 The automation system shown in has a superordinated controller 1 which can be implemented, for example, with a memory-programmable controller, PLC. Such a PLC 1 is basically used for controlling and regulating processes carried out by the automation system. At present, however, the PLC1 in the automation system also assumes extensive functions, such as visualization, alarming and recording of all process-related data, and the PLC1 itself functions as a human-machine interface. There are PLC1s of different performance levels with different indicators (computing power, storage capacity, number and type of input and ...

Abstract

The invention relates to a method for operating a data bus subscriber (7a, 7b,..., 7n) of a local bus (6), particularly of a ring bus, said method comprising: receiving a first data packet (17) over the local bus (6), wherein the first data packet (17) has an address (19) of the data bus subscriber (7a, 7b,..., 7n) to which it is directed and at least one instructions list (27a, 27b and 27n), having a set of instructions for processing process data (25a, 25b, 25c); receiving a second data packet (22) over the local bus (6), wherein the second data packet (24) has process data (25a, 25b and 25c); and executing instructions of the at least one instructions list (27a, 27b and 27n) for processing the received process data (25a, 25b and 25c). The invention further describes a corresponding databus subscriber (7a, 7b,..., 7n) and a local bus master.

Description

technical field [0001] The invention relates generally to the initialization of data bus subscribers and in particular to the programming of data bus subscribers of a ring bus by means of a command list. Background technique [0002] Data bus subscribers are mostly located in automation systems. Data bus subscriber devices are used to control or monitor processes in automation systems. This is done, for example, by outputting control signals to actuators and / or by receiving measurement signals, for example by sensors of the automation system. [0003] Automation systems are used inter alia to control industrial plants, buildings and vehicles. For controlling automation systems, multiple sensors and actuators are mostly required. These sensors and actuators monitor and control the processes performed by the system. The various sensors and actuators of an automation system are often also referred to as automation devices in this case. [0004] These automation devices can...
