Abstract
A method for operating a local bus, in particular a ring bus, including data bus participants, as well as a local bus master are described. The method comprises transmitting a first identifier of a cycle frame, the first identifier defining the beginning of the cycle frame; transmitting process data and management data over the local bus, the process data and management data being transmitted within the cycle frame, at least one isochronous data packet containing the process data being transmitted in a first time interval for the first identifier, and, if management data is transmitted within the cycle frame, this management data is transmitted separately from the process data.
Claims14
A method for operating a local bus, in particular a ring bus, including data bus participants, the method comprising:
- transmitting a first identifier of a cycle frame, the first identifier defining a beginning of the cycle frame;
- transmitting process data and management data over the local bus, the process data and the management data being transmitted within the cycle frame,
- wherein, in a first time interval for the first identifier, at least one isochronous data packet is transmitted that contains the process data, and
- wherein management data is transmitted within the cycle frame, the management data being transmitted separately from the process data.
A local bus master of a local bus, in particular a ring bus, including data bus participants, the local bus master comprising:
- a transmitter to transmit a first identifier of a cycle frame, the first identifier defining a beginning of a cycle frame,
- wherein the transmitter is adapted to transmit process data and management data over the local bus, the process data and the management data being transmittable within the cycle frame,
- wherein the transmitter is adapted to transmit at least one isochronous data packet containing the process data in a first time interval for the first identifier, and
- wherein the transmitter is adapted to transmit management data separately from the process data when management data is to be transmitted within the cycle frame.
