Abstract
It is provided to implement a different number of logical slaves in a field device for use in an AS interface network as a function of the assigned address, which slaves may be addressed using the assigned address in the standard or in the expanded addressing mode. Thus, in a field device, it is possible to provide slaves having different profiles, via which different data types may be exchanged. Furthermore, a method is provided, with which a field device having different slaves is able to be addressed in a simple manner while avoiding double addressing.

1-19. (canceled)
A device, comprising:
- at least two bus participants connected by a connection to at least one of (a) a bus, (b) an electric cable, (c) a current bus, and (d) air;
- and
- an assignment device adapted to assign a data at least one of (a) flowing in through and (b) exchanged through the connection to the bus participants.
A system, comprising:
- a device connected to a bus;
- wherein the device is adapted to implement, in a first mode, one of (a) a logical slave and (b) a bus participant, and to implement, in a second mode, one of (a) at least two logical slaves and (b) at least two bus participants.
A system, comprising:
- a device adapted to connect to a bus;
- wherein the device is adapted to implement one logical slave while operated using a standard address and to implement at least two logical slaves while operated with an address other than the standard address.
A system, comprising:
- a device adapted to connect to a bus, the device including a computer, a state machine of at least two bus participants being represented in the computer.
A method for addressing a device provided as a bus participant having two logical slaves, comprising:
- providing the device with at least one of (a) a standard address and (b) an address 0, before addressing and operation in at least one of (a) a first mode and (b) a standard addressing mode;
- assigning another address to the device;
- and
- implementing by the device at least two logical slaves after address assignment.
A converter, comprising:
- at least one of:
- (a) a device including:
- at least two bus participants connected by a connection to at least one of (a) a bus, (b) an electric cable, (c) a current bus, and (d) air;
- and
- an assignment device adapted to assign a data at least one of
- (a) flowing in through and (b) exchanged through the connection to the bus participants;
- (b) a device connected to a bus, wherein the device is adapted to implement, in a first mode, one of (a) a logical slave and (b) a bus participant, and to implement, in a second mode, one of (a) at least two logical slaves and (b) at least two bus participants;
- and
- (c) a device adapted to connect to a bus, wherein the device is adapted to implement one logical slave while operated using a standard address and to implement at least two logical slaves while operated with an address other than the standard address.
