Automation network and method for monitoring the security of the transfer of data packets
First Claim
1. An industrial automation network for monitoring the security of a transfer of data packets, comprising:
- a first processing device configured to transfer a data packet from an plant component and to the plant component; and
a second data processing device bidirectionally connected to the first data processing device, said second data processing device configured to generate at least one response packet, when detecting a transmission of the data packet from the first data processing device, and to send the at least one response packet back to the first data processing device;
said first data processing device including a response filter which is configured to execute a check and subsequent rejection/acceptance of the at least one response packet;
wherein the industrial automation network is a network selected from a control automation installation network, a production automation installation network, a manufacturing automation installation, and any combination thereof; and
wherein the plant component comprise at least one input and/or output facility which can detect process parameters and/or can output corresponding actuating signals.

Abstract
An automation network for monitoring the security of a transfer of data packets includes a first processing device configured to transfer a data packet from an installation component and to the installation component, and a second data processing device which is bidirectionally connected to the first data processing device. The second data processing device generates at least one response packet, when detecting a transmission of the data packet from the first data processing device, and sends the at least one response packet back to the first data processing device. The first data processing device includes a response filter which is configured to execute a check and subsequent rejection/acceptance of the at least one response packet.

11. A method for monitoring the security of a transfer of data packets in an industrial automation network, having first and second data processing devices which are bidirectionally connected to one another, the method comprising:
-
at the first data processing device, communicating of a data packet from a plant component and to the plant component; at the second data processing device, generating at least one response packet, when detecting a transmission of the data packet from the first data processing device, and sending the at least one response packet back to the first data processing device; and at the first data processing device, checking and subsequently accepting or rejecting response packets by a response filter; wherein the Industrial automation network is a network selected from a control automation installation network, production automation installation network, a production automation installation, a manufacturing automation installation, and any combination thereof; and
,wherein the plant component comprise at least one input and/or output facility which can detect process parameters and/or can output corresponding actuating signals. - View Dependent Claims (12, 13, 14, 15, 16, 18)
