## Abstract

A method transmits temporally successive datasets of a position sensor via an Ethernet network, wherein a respective dataset of the position sensor consists of a maximum of 4 bits. The method includes the steps of: continuous reading, by a reference component connected to the Ethernet network, of the datasets of the position sensor which are to be transmitted; and continuous writing, by the reference component, of a respective dataset to a 4-bit transmit register of a Media Independent Interface of the reference component.

## Claims

### Claim 1

A method for transmitting temporally successive datasets of a position sensor via an Ethernet network, wherein a respective dataset of the position sensor consists of a maximum of 4 bits, the method comprising:
continuous reading, by a reference component connected to the Ethernet network, of the datasets of the position sensor which are to be transmitted; and
continuous writing, by the reference component, of a respective dataset to a 4-bit transmit register of a Media Independent Interface of the reference component.

### Claim 2 (depends on 1)

The method according to claim 1, wherein
the position sensor is an incremental sensor which generates an A-track bit, a B-track bit and a Z-track bit, and
the A-track bit, the B-track bit and the Z-track bit are written to the 4-bit transmit register.

### Claim 3 (depends on 2)

The method according to claim 2, wherein
a fourth bit of the 4-bit transmit register serves to transmit further payload data.

### Claim 4 (depends on 3)

The method according to claim 3, wherein
the further payload data represent an absolute value, and/or represent a barcode, and/or represent a gear factor.

### Claim 5 (depends on 2)

The method according to claim 2, wherein
the data transmitted by way of the reference component are received and evaluated by a number of receiver components connected to the Ethernet network.

### Claim 6

An electrical drive system comprising:
an Ethernet network;
a position sensor;
a reference component coupled with the position sensor and connected to the Ethernet network; and
a number of receiver components connected to the Ethernet network, wherein
the electrical drive system operates to transmit temporally successive datasets of the position sensor via the Ethernet network, wherein a respective dataset of the position sensor consists of a maximum of 4 bits, by:
continuous reading, by the reference component connected to the Ethernet network, of the datasets of the position sensor which are to be transmitted; and
continuous writing, by the reference component, of a respective dataset to a 4-bit transmit register of a Media Independent Interface of the reference component.

### Claim 7 (depends on 6)

The electrical drive system according to claim 6, wherein
the reference component and/or the receiver components are frequency converters.
