摘要:
The following process steps are carried out in a method for monitoring a process system having a field bus FB in the process automation technology, via which a plurality of field devices F1-F4 exchange telegrams with a process controller SPS for process control in regular data traffic. The telegrams transmitted via the field bus TR for process control SPS are tapped by a monitoring application UA, which performs an examination of the telegrams for data relevant for the monitoring application UA. Any data relevant for the monitoring application UA is processed as the actual value in a process model application, which is part of the monitoring application. An error signal is generated, if any significant deviation is detected between the target and actual values.

Die Erfindung betrifft ein Prozessdaten-Gateway (1) für die Kommunikation von Prozessdaten zwischen einem Prozessdaten-Client (2) und einem Prozessdaten-Server (3a, 3b, 3c). Das Prozessdaten-Gateway (1) weist einen WebSocket-Server (4) auf, welcher dazu eingerichtet ist, eine Anfrage zum Lesen oder Schreiben von Prozessdaten (items) gemäß eines Prozessdaten-Protokolls (pdi) von dem Prozessdaten-Client (2) entgegen zu nehmen. Das Prozessdaten-Gateway (1) weist ferner eine Prozessdaten-Logik (5) auf, welche dazu eingerichtet ist, die Anfrage zum Lesen oder Schreiben von Prozessdaten gemäß des Prozessdaten-Protokolls (pdi) zu interpretieren und in eine Anfrage gemäß eines Kommunikationsprotokolls (OPC-Classic, OPC-UA) eines Prozessdaten-Servers (3a, 3b, 3c) zu übersetzen. Das Prozessdaten-Gateway (1) weist ferner ein Interface (6a, 6b, 6c) auf, das als Schnittstelle zu einem Prozessdaten-Server (3a, 3b, 3c) dient und dazu eingerichtet ist, die übersetzte Anfrage zum Lesen oder Schreiben von Prozessdaten (items) an den Prozessdaten-Server (3a, 3b, 3c) zu senden.

The invention relates to a method for transmitting a process map of a control or automation system via a gateway device (20), which comprises at least one first functional unit (21), to which a higher-ranking control unit is connected via a first communications link (1) based on a primary field bus protocol, and at least one second functional unit (22), to which at least one field device (30) is connected via a second communications link (2) based on a secondary field bus protocol. Process variables provided by the field devices (30) are transmitted as process data objects (PDO1), (PDO2) based on the secondary field bus protocol (2) into the second functional unit (22) of the gateway device (20), which operates as a master task, as telegrams. The process data objects (PDO1), (PDO2), which are present as digital signals, are assigned corresponding registers (Bool1), (Bool2), (Bool3), which are present in binary form. The process data objects (PDO1), (PDO2) present as analog objects are assigned corresponding addresses in the integer format (INT16). The binary signals (Bool1), (Bool2), (Bool3) stored in the corresponding registers and the analog signals present in the integer format (INT16) are transmitted into the first functional unit (21) that operates as a gateway task in such a manner that the number of binary signals is reduced by packing the binary signals into data blocks of eight bits each, which then respectively form a byte and are translated into corresponding telegrams that can be processed by the primary field bus protocol (1) which, together with the analog signals present in the integer format (INT 16), are transmitted to the higher-ranking control unit on the basis of the primary field bus protocol (1).
摘要:
Methods, systems, and computer program products sustain a fleet of configuration-controlled assets. The method involves integrating a plurality of previously separate systems with reusable business transactions associated with managing a fleet of vehicles. The method also involves receiving operational data associated with a vehicle of the fleet, integrating the operational data per customer requirements, packaging and distributing the operational data to the plurality of systems, and installing and distributing the operational data to one or more applications of the plurality of systems utilizing reusable business transactions. The system utilizes a plurality of applications and a plurality of logical subsystems, which are connected to each other through gateways. The logical subsystems use a common format defined by a set of messages. However, the applications can use a plurality of different formats. The gateways, which are the connecting blocks, convert the data flow between the logical subsystems and the applications.

The invention relates to a connection unit (100) for transmitting process data of an automation process of an automation system (1) to an external data infrastructure (4), which is designed as a field device for arrangement in a field plane (20) of the automation system (1). The connection unit (100) comprises a field bus module (110), a network module (130) and an interface module (120). The field bus module (110) can be connected to a field bus (102) and is designed to exchange the process data via the field bus (102) with a signal unit (40, 41, 42, 43) that is connected to the automation process via a field connection (25). The network module (130) can be connected to an external data network (7) and is designed to exchange the process data via the external data network (7) with the external data infrastructure (4). The interface module (120) is connected to the network module (130) and the field bus module (110) for an exchange of the process data between the field bus module (110) and the network module (130), and is designed to independently permit the exchange of the process data between the network module (130) and the external data infrastructure (4).
