Abstract

An apparatus and method for allowing at least one second device configured to use a second communication protocol to communicate with at least one first field device configured to use a first communication protocol. The apparatus including a first network communication arrangement configured to communicate with the at least one first field device using the first communication protocol, a second network communication arrangement configured to communicate with the at least one second device using the second communication protocol, and a device emulation processing arrangement configured to emulate the at least one first field device such that the at least one second device may communicate with the emulated at least one first field device using a third communication protocol.

Claims

1. A system configured to allow at least one first device which is configured to use a first communication protocol to communicate with at least one second field device configured to use a second communication protocol, comprising:

a first network communication arrangement configured to communicate with the at least one first device using the first communication protocol;

a second network communication arrangement configured to communicate with the at least one second device using the second communication protocol; and

a device emulation processing arrangement configured to emulate the at least one second field device such that the at least one first device is capable of communicating with the emulated at least one second field device using a third communication protocol.

2. The system of claim 1, wherein the first communication protocol is a network protocol.

3. The system of claim 1, wherein the first communication protocol is one of a HART™

protocol, a FOUNDATION™

Fieldbus protocol and a PROFIBUS™

protocol.

4. The system of claim 1, wherein the first communication protocol is a 4-20 mA analog communication protocol.

5. The field device of claim 1, wherein the first communication protocol is a digital communication protocol.

6. The field device of claim 1, wherein the device emulation processing arrangement includes at least one circuit, and wherein the at least one first field device is one of a temperature sensor, a pressure sensor, a flow rate sensor, a valve and a switch.

7. The field device of claim 1, wherein the second communication protocol is a network protocol.

8. The field device of claim 1, wherein the second communication protocol is a high speed ethernet protocol.

9. The field device of claim 1, wherein the third communication protocol is a FOUNDATION™

Fieldbus H1 protocol.

11. The method of claim 1, wherein the first communication protocol is a network protocol.

12. The method of claim 1, wherein the first communication protocol is one of a HART™

protocol, a FOUNDATION™

Fieldbus protocol and a PROFIBUS™

protocol.

13. The method of claim 1, wherein the first communication protocol is a 4-20 mA analog communication protocol.

14. The method of claim 1, wherein the first communication protocol is a digital communication protocol.

15. The method of claim 1, wherein the second communication protocol is a network protocol.

16. The method of claim 1, wherein the second communication protocol is a high speed ethernet protocol.

17. The method of claim 1, wherein the third communication protocol is a FOUNDATION™

Fieldbus H1 protocol.

10. A method for allowing at least one second device configured to use a second communication protocol to communicate with at least one first field device configured to use a first communication protocol, comprising:

communicating with the at least one first field device using the first communication protocol;

emulating the at least one first field device; and

communicating with at least one second device using a second communication protocol, wherein the at least one second device may communicate with the at least one first field device using a third network protocol.
