Abstract

A front adapter for connecting to a control device, has a connection device connected to a predetermined system cable for connecting at least one field component, at least one wireless communication interface for wirelessly transmitting and receiving signals to or from at least one wireless one transmitting and/or receiving device which can be connected to a first field unit, and/or at least one bus-capable communication interface for transmitting and receiving signals via a signal bus to or from at least one bus-capable transmitting and/or receiving device which can be connected to a second field device, and a control and/or evaluation device which is adapted to control the transmitting of signals between the control device and the at least one wireless transmitting and/or receiving device and/or the at least one bus-capable transmitting and/or receiving device.

First claim

The invention claimed is:

1. A front adapter for connecting to a control device, comprising:
a connection device connected to a predetermined system cable having a plurality of individual fibers or wires, for connecting at least one field component, the connection device having first contact elements, the individual fibers or wires of the predetermined system cable each connected to a respective one of the first contact elements;
at least one wireless communication interface for wirelessly transmitting and receiving signals to or from at least one wireless for transmitting and/or receiving device that can be connected to a first field device and/or at least one bus-capable communication interface for transmitting and receiving signals via a signal bus to or from at least one bus-capable for transmitting and/or receiving device that can be connected to a second field device;
a control and/or evaluation device connected to the at least one wireless communication interface and/or to the at least one bus-capable communication interface, and to second contact elements; and
a housing encasing the connection device, the at least one wireless communication interface and/or the at least one bus-capable communication interface, and the control and/or evaluation device;
wherein the front adapter is configured as a single plug-in connector with the first contact elements configured complementary to and electrically connectable to first I/O contact elements of an input/output assembly of the control device and the second contact elements configured complementary to and connectable to second I/O contact elements of the input and output assembly of the control device; and
wherein the control and/or evaluation device is adapted to control the transfer of signals between the second I/O contact elements of the input and output assembly and the at least one wireless transmitting and/or receiving device and/or the at least one bus-capable transmitting and/or receiving device.

2. The front adapter of claim 1 , wherein:
each wireless and/or bus-capable transmitting and/or receiving device has a unique address assigned thereto; and
the control and/or evaluation device is adapted to control the transfer of signals between the second I/O contact elements of the input and output assembly and the at least one wireless transmitting and/or receiving device and/or the at least one bus-capable transmitting and/or receiving device in response to these addresses.

3. The front adapter of claim 1 , wherein the at least one wireless communication interface is adapted for optical signal transfer or for wireless transfer, and the bus-capable communication interface is adapted for connecting a wired or glass fiber bound signal bus.

4. The front adapter of claim 1 , further comprising an interface for parameterization and/or configuration of the front adapter.

5. The front adapter of claim 1 , further comprising an internal power supply source and/or an interface for connecting an external power supply source.

6. An automation system, comprising:
the front adapter of claim 1 , configured to be externally connectable to the control device;
the at least one wireless transmitting and/or receiving device connected to the first field device and adapted for wireless communication with the front adapter; and/or
the at least one bus-capable transmitting and/or receiving device connected to the second field device and adapted for bus-based communication with the front adapter.

7. The automation system of claim 6 , wherein the at least one wireless transmitting and/or receiving device and/or the at least one bus-capable transmitting and/or receiving device is arranged in a respective separate housing and is adapted to be externally connected to the respective field device assigned to it.

8. The automation system of claim 6 , wherein the at least one wireless transmitting and/or receiving device and/or the at least one bus-capable transmitting and/or receiving device is implemented in the respective field device assigned to it.

9. The automation system of claim 6 , wherein the first and/or second field device is implemented as an actuator or a sensor.

10. The automation system of claim 6 , wherein the first and second field devices are not adapted to be connectable to the system cable.

11. The automation system of claim 6 , further comprising field components adapted to be connected to the system cable.
