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.
Claims22
A device, comprising:
- at least two bus participants connected by a connection;
- and
- an assignment device adapted to assign a data to the bus participants,
- wherein the device includes a reversing logic adapted to shift the device from a first mode to a second mode, wherein the device includes a processing device that simulates one bus participant as a logical slave in the first mode, and wherein in the second mode the at least two bus participants are simulated without reconfiguration as at least two logical slaves within the processing device.
A system, comprising:
- a device connected to a bus;
- wherein the device is adapted to implement a first mode and a second mode,
- wherein the device includes a reversing logic adapted to shift the device from the first mode to the second mode, wherein the device includes a processing device that simulates one bus participant as a logical slave in the first mode, and wherein in the second mode at least two bus participants are simulated without reconfiguration as at least two logical slaves within the processing device.
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,
- wherein the device includes a reversing logic adapted to shift the device from a first mode to a second mode, wherein the device includes a processing device that simulates the one logical slave in the first mode, and wherein in the second mode the at least two logical slaves are simulated without reconfiguration within the processing device.
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,
- wherein the device includes a reversing logic adapted to shift the device from a first mode to a second mode, wherein the device includes a processing device that simulates one logical slave in the first mode, and wherein in the second mode at least two logical slaves are simulated without reconfiguration within the processing device.
A method for operating a device provided as a bus participant having two logical slaves, comprising:
- assigning an address to the device during a first mode;
- and
- implementing by the device at least two logical slaves after address assignment, the implementing including operating a processing device of the device to simulate without reconfiguration the at least two logical slaves during a second mode;
- wherein the device includes a reversing logic adapted to shift the device from a first mode to the second mode depending on the address.
A converter, comprising:
- a device adapted to connect to a bus, wherein the device is adapted to implement a first mode involving one logical slave and to implement a second mode involving at least two logical slaves,
- wherein the device includes a reversing logic adapted to shift the device from the first mode to the second mode, and
- wherein the device adapted to connect to the bus includes a processing device that simulates the one logical slave in the first mode and simulates without reconfiguration the at least two logical slaves in the second mode.
