Definitions
- the invention relates to a system for controlling a Prozes ⁇ ses, for example, a manufacturing process in which a server device to at least one process parameter, Example ⁇ example a temperature, determines the current process value to different transmit times and here referred to several other Ge ⁇ councils, client devices distributed.
- a server device to at least one process parameter, Example ⁇ example a temperature
- client devices distributed.
- To the invention also include a corresponding server device and a client device entspre ⁇ and fair and a method for operating the server device.
- OPC Unified Automation OPC UA
- OPC - OLE for process control
- OLE - object linking and embedding OPC - object linking and embedding
- OPC UA secures this data transport eg by acknowledgment of receipt.
- OPC UA requires that the client and the server know each other. A concrete peer-to-peer connection between client and server is established, the so-called OPC UA session.
- UDP User Datagram Protocol
- UDP is a minimal, connectionless network protocol that belongs to the transport layer of the Internet protocol family.
- UDP allows applications to send datagrams in IP-based computer networks.
- UDP addresses the problem of the 1: n relationship, but introduces new problems, such as that of a non-secure Kom ⁇ munication with it.
- the UDP approach also brings new possibilities of attack to the net, or the productive
- Communication such as flooding the network with large volumes of data packets.
- the OPC UA layer has it according to protocol no Einwir ⁇ kung facilities on the network level.
- Clients are, as mentioned above, used in OPC UA subscriptions (subscriptions): a client creates such a subscription on a server and adds the elements whose value change he wants to be informed. As soon as this subscription has been set up successfully, the client is informed about value changes of the entered elements.
- a client can create several subscriptions. In addition to the information about what items he wants to be informed, the subscription also contains information in what form or how often he wants to receive this information / updates.
- the client makes a request / request to the server, which is answered by the server with a response / response as soon as a data change occurs.
- the server must manage the pending requests / requests and send keep-alive messages to the client if no change in value occurs.
- each individual client on the server must create their own subscription and add the corresponding elements.
- the server must then send a notification with the same content to each client. If you do not want to invest the cost of a subscription, the client can also just make a READ request to the server.
- the server does not have to manage the subscription mechanism, each time a read is accessed, a context must be set up that the server uses to match variable names to actual variable access.
- Client and server are established a session that is valid as long as the client is interested in value changes.
- multi-target UDP Subskriptio ⁇ nen for OPC UA.
- multiple clients can be clustered into multicast clusters to minimize management and transport load.
- the invention is therefore based on the object to make an off ⁇ exchange of process values between devices in a plant efficiently.
- a method is provided by means of which a server or server device is operated in a system.
- a server or server device may be an automation ⁇ technical plant, for example, for the production of a product (for example, the manufacturing of a motor vehicle) or for performing a process (such as the power generation on the basis of nuclear power) or CON ⁇ ren a system (for example, controlling traffic lights in a municipality).
- the process can also be arranged within a single apparatus, for example it can be the control of a robot for coordinating individual devices of the robot, for example its sensors and actuators.
- Another apparatus can be for example a manufacturing station, for example, a Lackiersta ⁇ tion or a bottling station. Even within such stations, a process can provide the desired functionality of the station. Therefore covered by the term "plant” also preferred such an apparatus and such states ⁇ on.
- the controlled process includes at least one process parameter, which may be changed by the operation of the process, such as a temperature, a pressure, a rotational position of, for example, a rotor or shaft, or a Ge ⁇ speed, for example, an assembly line.
- the Serverge ⁇ advises determined at different transmission times to the at least one process parameter in each case one current process value, ie for example the current temperature or the current pressure.
- the server device may have, for example, a temperature sensor or a pressure sensor or a motor control for an electric motor or a control device for a robot.
- the respective current process value of the at least one Pro ⁇ zessparameters should excluded to multiple client devices of the plant be sent.
- a client device may also be, for example, a motor controller or another actuator controller or a sensor.
- each of the client devices can either require the current process value from the server device for each of the at least one process parameters, or even only a subset thereof, that is, one or several.
- the server device sends to a plurality of client devices of the system depending ⁇ wells to each or a subset of the at least one Pro ⁇ zessparameters the respective transmission time of the respective ER-mediated current process value via a data network, such as an Ethernet or a Profinet bus from.
- the server device performs the following:
- the server device constituting a group of at least one Pro ⁇ process parameters, which is for For ⁇ send to at least one of the client devices.
- the server device holds a transmission time point each ⁇ wells the current process values of the at least one process parameter of the group into a single TSN telegram and sends the TSN telegram in the data network.
- server device is not restricted to a device that operates exclusively as a data source for process values.
- the server device for the at least one process parameter may be a client device associated with at least one other process parameters at the same time that current Pro ⁇ zess uncomfortable to receive at least one other process parameters from another server device.
- the idea is not to transmit requested OPC-UA subscriptions over the conventional OPC-UA session channel, but instead
- Time-sensitive networking is a set of standards that the Time-Sensitive Networking Task Group (IEEE 802.1) uses.
- TSN describes advanced Layer 2 mechanisms and protocols for Bridges and terminals to, among other things determinism to guarantee ⁇ ren.
- There are existing protocols and expand into new protocols established z. B. Protocols for Pfadberech ⁇ planning and booking
- determinism is a fundamen- tional requirement for Ethernet-based networks in order to be able to be used in the factory floor of automation systems (of course also energy, automotive, etc.).
- a server device may be a performance-weak device, such as a sensor.
- the invention also includes a device for a system for controlling a process, which can act as a client device.
- the device is designed to emit a request telegram to a server device, is indicated in which of which of, process values are to send out at least one process parameter being monitored by the server device to the client device depending ⁇ wells.
- the client device sends this request diagram over a data network.
- the device is designed to further sending to a server device a request ⁇ telegram and receive group information via the data network from the server device.
- An addressed TSN telegram is then received via the data network at different transmission times and at least one process value contained therein is read from the TSN telegram.
- the invention still includes a system for controlling a process. Which processes it can be ⁇ example, has already been listed.
- the system includes at least a server device and a plurality of Clientge ⁇ boards according to the invention.
- FIG. 2 shows an exemplary network with a server and a plurality of client devices
- FIG. 3 shows a flowchart for an embodiment of the method according to the invention, which can be carried out in the system of FIG.
- a client requests one or more subscriptions with one or more items (monitored items) and properties (eg publishing rate) from the server.
- FIG. 1 shows by way of example 5 servers which request information as follows:
- Entity group 2
- the server forms (or complements) these groups, El, E2. These groups form the basis for managing subscriptions in the server.
- a group contains several process parameters v, w, x, y, z (monitored items) to be monitored potentially different Clients Client A, Client B, ... based on properties together. Properties can z. B. the publishing rate or a requested quality (Garan ⁇ tie) the transmission, etc. be.
- Groups are not a 1: 1 mapping of the subscription request of a single client, but rather an optimized summary / split of different subscription requirements of different clients.
- it can not be determined that new groups will be needed for the new subscription. In this case, the client is only informed which
- Calculated paths and reservations ensure that the communication of the network does not interfere with the network. This requires no additional administrative ⁇ maintenance effort in the OPC UA client or server.
- the communication between the client and the server is shown as an example, after the subscription of the client at the server, the server receives it at regular intervals
