  • Page 10: Principle Of Operation

    The USS protocol uses a master/slave network for communication via a serial bus. The master (SIMATIC controller) uses an address parameter to send a message to a selected slave (SINAMICS V20). A slave cannot send without having received a request for sending. Direct information transmission between the individual slaves is not possible.

    Default values The below parameterization of the SINAMICS V20 assumes that the device is in the as-supplied state or has been reset to factory default. In this state, there is a default parameterization that forms the basis for Table 4-1. Parameters that do not have to be changed for this application example regarding the default values will not be mentioned in the following sections.
