摘要:
Process-related modules (8 to 11) contain means (15 to 18) for automatically running predetermined functions for the purpose of process automation. Each module (8 to 11) has a memory (22 to 25) which contains module-specific information on the function of the module (8 to 11) and its connections to the measurement, control and regulation equipment. During an initialisation phase, this information is transmitted to a central communication device (4) in which it is stored for access by a control and monitoring device (1) which thus can automatically add this information to its control and monitoring surface.

In a plant for controlling an equipment (4) adapted to carry out a process a superior arrangement (1) exists and has a first interface (2) to a programming unit (3) and a second interface (5) between the process equipment (4) and the arrangement. The arrangement has members (6) for trasnmitting information between the two interfaces. A memory member (9) adapted to store important data required for describing and defining the process of the process equipment is arranged in the process equipment itself. The arrangement (1) is provided with a rule data base (8) and a text data base (7) containing a configuration file for communication between the process equipment and the arrangement through the second interface by utilising a general process application protocol and a text file, respectively, adapted to the format of said data in the memory member of the process equipment.
摘要:
In a plant supervisory system, many computers (functional servers) that distributively perform functions are connected through two types of transmission paths (such as a control bus and an information bus). The control bus is used to transmit periodic data such as process data. Event data is transmitted through the information bus. Thus, many computers can be connected. In addition, the latest value of process data can be referenced by each computer.
摘要:
The invention relates to a method for controlling a packaging machine, particularly a filling machine, in which at least two mutually-independent packaging machine operational states are defined, at least one of a plurality of defined process sequences being associated with each of these operational states, and at least one actuator of said packaging machine being actuated by a process sequence in order to carry out at least one action. Improved control and maintenance for the machine is achieved in that an access justification to an actuator is exclusively associated with precisely one process sequence, depending on the operational state.

A system and method for debugging and tuning a process control network having distributed control functions implemented by a set of field devices communicatively linked over a bus include an operational scheduler that schedules the execution of each of a number of process control functions and communication functions performed by the field devices to define a process control scheme and an indicator that indicates one or more process control scheme locations at which the process control scheme is to be automatically or conditionally interrupted to thereby enable debugging and/or tuning of the process control network. A controller interrupts execution of the process control scheme at the indicated flow locations, communicates process data to a user to display the current or a past state of the process to a user and waits for user input before continuing with operation of the process control scheme. In a tuning mode, the controller delivers data pertaining to a process parameter to a tuning device or to a user which determines a new tuning parameter, such as a gain, to be used within the process control scheme based on the process parameter data.

摘要:
Ein Verfahren zum Betreiben einer Prozessanlage (1), bei der auf Prozessebene (3) eine Anzahl von Alarminformationen (Alarm Ai,Bi,Ci) zum Anzeigen nicht ordnungsgemäßer Betriebsvorgänge der Prozessanlage (1) generiert werden, zeichnet sich dadurch aus, dass a) eine Anzahl von Prozesszuständen (Zustand Ai,Bi,Ci) der Prozessanlage (1) definiert wird, b) jeder Prozesszustand mit der Summe der generierbaren Alarminformationen korreliert wird, wobei jedem aus einem Prozesszustand und einer Alarminformation gebildeten Paar ein erster Wert oder ein zweiter Wert als Korrelationswert zugewiesen wird, c) ein gegenwärtiger Prozesszustand der Prozessanlage bestimmt wird, d) in Abhängigkeit von dem bestimmten Prozesszustand diejenigen Alarminformationen nicht zur Anzeige gebracht werden, denen als Korrelationswert der erste Wert zugewiesen wurde.
