ARRANGEMENT AND A METHOD FOR SAFE DATA COMMUNICATION VIA A NON-SAFE NETWORK
First Claim
1. Arrangement for safe data communication via a non-safe network with a safe data transmitter that transmits safe data according to a safety protocol encapsulated in the network protocol via the network to a safe data receiver, wherein a network protocol-dependent transmitter optimization device connected to the network is provided on the transmitter side, which device receives the safe data from the safe data transmitter and, independent of the safety protocol, subdivides or combines them on network protocol-specific data packets of specific predetermined payload lengths and transmits the network protocol-specific data packets via the non-safe network, and in that a network protocol-dependent receiver optimization device connected to the network is provided on the receiver side, which device extracts or assembles the safe data from the network protocol-specific data packets and forwards these data to the safe data receiver.

Abstract
In order to utilize the bandwidth available in the non-safe network for sending safe data in the best possible manner, it is provided for the safe data on the transmitter side to be combined by a network protocol-dependent transmitter optimization device in a network message or divided among several network messages and transmitted via the non-safe network. On the receiver side the safe data are extracted or combined again from the network protocol-specific data packets by a network protocol-dependent receiver optimization device.

- 8. Method for transmitting safe data via a non-safe network in which safe data are transmitted according to a safety protocol encapsulated in the network protocol via the network by a safe data transmitter to a safe data receiver, wherein on the transmitter side the safe data are received by the safe data transmitter and divided up or combined on network-specific data packets of specific predetermined payload lengths in a network protocol-dependent transmitter optimization device connected to the network independent of the safety protocol, and the data packets are transmitted via the non-safe network and that on the receiver side the safe data are extracted or combined from the network protocol-specific data packets received in a network protocol-dependent receiver optimization device connected to the network and are forwarded to the safe data receiver.
