Assignee: ABB SCHWEIZ AG
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 2:
3. A method for transmitting a second data packet from a sending input-buffer to a sending output-buffer, wherein the second data packet in the sending input-buffer is Time-Sensitive Network (TSN) compliant and the second data packet in the sending output-buffer has a non-TSN format, wherein the non-TSN format is one of: Profinet, EtherCat, Powerlink, Ethernet/IP, TTEthernet, and/or Modbus TCP protocol, the method comprising the steps of:
analysing the second data packet, which has been retrieved from a TSN-compliant device, in the sending input-buffer, wherein the second data packet comprises at least a second data packet time and a second data packet priority level;
acknowledging the second data packet according to the second data packet priority level;
modifying the second data packet priority level from the second data packet according to the Priority Code Point (PCP);
modifying the second data packet time from the second data packet according to the Precision Time Protocol (PTP);
transmitting the second data packet to the sending output-buffer; and
sending the second data packet to a non-TSN device.
