Patent ID: 11704261

Abstract:
The invention relates to a system for establishing a data connection between a master unit (M) and at least one device unit (D), wherein the master unit (M) is coupled to a primary coupler unit (Dprim) and the at least one device unit (D) is coupled to a secondary coupler unit (Dsec), in each case for electrical power transmission and for data transmission. The primary coupler unit (Dprim) and the secondary coupler unit (Dsec) can be coupled for data transmission. A control signal can be received and the system has three operating states that can be activated in dependence on the received control signal. When the first operating state is activated, there is a data connection according to the IO-Link standard between the master unit (M) and the device unit (D). When the second operating state is activated, primary coupler identification data (Dprim-ID) are allocated to the primary coupler unit (Dprim), wherein there is a data connection according to the IO-Link standard between the master unit (M) and the primary coupler unit (Dprim). When the third operating state is activated, secondary coupler Identification date (DsecID) are allocated to the secondary coupler unit (Dsec), wherein there is a data connection according to the IO-Link standard between the master unit (M) and the secondary coupler unit (Dsec). The invention furthermore relates to a method for operating the system.
