Abstract
A connecting plug for connecting an input/output unit to a machine control with a central bus, wherein the input/output unit is to be connected to a multi-strand electrical cable connected to a bus node, has a housing with a first plug connection for an incoming cable and a second plug connection for an outgoing cable. The incoming cable is looped through to the outgoing cable forming a looped-through cable. The housing has a connector for the input/output unit. An electronic device is arranged in the housing and connected to the connector. The connector is connected by the electronic device to the looped-through cable.
Claims12
A connecting plug for connecting an input/output unit to a machine control comprising a central bus, wherein the input/output unit is to be connected to a multi-strand electrical cable connected to a bus node, the connecting plug comprising:
- a housing (12, 12a) comprising a first plug connection (20) for an incoming cable (21) and a second plug connection (30) for an outgoing cable (31), wherein the incoming cable (21) is looped through to the outgoing cable (31) forming a looped-through cable (7);
- the housing (12, 12a) comprising a connector (40) for the input/output unit (2, 3, 4, 5);
- an electronic device (15) arranged in the housing (12, 12a) and connected to the connector (40);
- wherein the connector (40) is connected by the electronic device (15) to the looped-through cable (7);
- wherein the electronic device (15) comprises en electronic switch (23) which interrupts a voltage supply to the plug connection (30) of the outgoing cable (31) in a rest position of the connecting plug (1) and the electronic switch (23) is closed by the electronic device (15) when the connecting plug (1) has been assigned an address by the machine control.
