Method and arrangement for data transmission between units on a bus system selectively transmitting data in one of a first and a second data transmission configurations |
摘要 |
The invention relates to a method and an arrangement for operating a bus system having at least one master unit and at least one slave unit, having a bus and a bus control unit for the bus arbitration and for controlling the data transfer. The data transmission is split into a request data transfer and a response data transfer, and, in the time between the request data transfer and the response data transfer, the bus is cleared for the data transmissions of other master units in a first data transmission configuration, or the bus is blocked between the request data transfer and the response data transfer, in a second data transmission configuration and slave units. In the case of a response transfer, the master and slave are changed round.
