Abstract
An automation network provides packet-based communication between the host and a client, wherein the client determines output values from the host in the event of errors in the communication between the host and the client, where the determination of output data can be performed in a separate local processing module in accordance with a less complex method than on the host, such that it becomes possible to perform complex open-loop and closed-loop control tasks on the host even in the case of mobile clients or other clients that are difficult to wire.
Claims17
A method for operating an automation network having a host device, at least one client device and a packet-based communication connection arranged between the host device and the client device, the method comprising:
- generating, by the at least one client device, input value packets and transmitting the generated input value packets to the host device via the packet-based communication connection;
- generating, by the host device, output value packets and transmitting the generated output value packets to the at least one client device via the packet-based communication connection;
- and
- generating, by the client device, a replacement output value packet if the at least one client device fails to receive at least one output value packet within a predefined period via the packet-based communication connection.
An automation network comprising:
- a host device;
- at least one client device;
- and
- a packet-based communication connection arranged between the host device and the at least one client device;
- wherein the at least one client device is configured to generate and transmit input value packets to the host device via the packet-based communication connection;
- wherein the host device is configured to generate and transmit output value packets to the at least one client device via the packet-based communication connection;
- and
- wherein the at least one client device is further configured to generate a replacement output value packet if the packet-based client device fails to receive at least one output value packet within a predefined period via the packet-based communication connection.
A host device comprising:
- a processor;
- and
- memory;
- wherein the host device is configured to:
- receive input value packets from a client device, said input packets being generated and transmitted by the client device via a packet-based communication connection;
- and
- generate output value packets and transmit the generated output value packets to the client device via the packet-based communication connection;
- and
- wherein the client device generates a replacement output value packet if the client device fails to receive at least one output value packet within a predefined period from the host device via the packet-based communication connection.
A client device comprising
- a processor;
- and
- memory;
- wherein the client device is configured to:
- generate input value packets and transmit the generated input value packets to a host device via a packet-based communication connection;
- receive output value packets from the host device via the packet-based communication connection, said output value packets being generated and transmitted to the client device via the packet-based communication connection;
- and
- generate a replacement output value packet if at least one output value packet is not received within a predefined period via the packet-based communication connection.
