Abstract

A master device is configured to perform a method that includes receiving highway addressable remote transducer (HART) device data of a HART slave device connected to PROFIBUS RIO Slave. The method also includes identifying a device description (DD) file associated with the HART slave device using the HART device data that is collected automatically based on the PROFIBUS slave Profile index before even configuring the HART device in the system. The method further includes performing one or more device communication functions with the HART slave device to collect the data automatically.

Claims

1. A method comprising:

before a completion of a software configuration of one or more highway addressable remote transducer (HART) devices, scanning the one or more HART devices connected to a PROFIBUS remote IO slave device and collecting HART device data about a HART slave device to choose a device description (DD) file configuration from a controller;

identifying a DD file associated with the HART slave device using the HART device data; and

performing one or more device communication functions with the HART slave device.

2. The method of claim 1, further comprising obtaining identification information from the HART slave device before completing the software configuration of the one or more HART devices.

3. The method of claim 1, wherein the HART device data of the HART slave device comprises automatically collected identification information before completing the software configuration of the one or more HART devices.

4. The method of claim 3, wherein a machine controller automatically configures the DD file for the HART slave device based on the identification information.

5. The method of claim 1, further comprising:

establishing a communication channel with the HART slave device when identifying the DD file associated with the HART slave device.

6. The method of claim 1, wherein the one or more device communication functions comprise at least one of:

opening a device data port (DP (V1)) connection to the HART slave device, wherein the HART slave device is connected to a PROFIBUS Remote IO slave device comprising HART inputs and outputs configured for HART data exchange;

or

sending one or more initialization DP (V1) write/retry/read commands.

7. The method of claim 1, wherein the one or more device communication functions are performed on all channels that can provide communication with the HART slave device automatically before the HART slave device is configured with a system implementing the method.

8. The method of claim 7, wherein the identification command information of the HART slave device comprises at least one of:

a device manufacturer identification (ID);

a device type;

or

a device revision number.

9. A master device comprising:

processing circuitry configured to;

collect highway addressable remote transducer (HART) device data of a HART slave device via a PROFIBUS slave;

identify a device description (DD) file associated with the HART slave device using the HART device data; and

perform one or more device communication functions with the HART slave device.

10. The master device of claim 9, wherein the processing circuitry is further configured to obtain HART identification information via the PROFIBUS slave for the HART device attached thereto.

11. The master device of claim 9, wherein a machine controller automatically configures the DD file for the HART slave device.

12. The master device of claim 9, wherein the processing circuitry is further to identify a communication channel with the HART slave device when identifying the DD file associated with the HART slave device.

13. The master device of claim 9, wherein the one or more device communication functions comprise at least one of:

opening a device data port (DP (V1)) connection to the PROFIBUS slave;

or

sending one or more initialization DP (V1) write/retry/read commands.

14. The master device of claim 9, wherein the processing circuitry is configured to perform the one or more device communication functions on all channels that can provide communication with the HART slave device.

15. The master device of claim 14, wherein the identification information of the HART slave device comprises at least one of:

a device manufacturer identification (ID);

a device type;

or

a device revision number.

16. A non-transitory, computer-readable medium storing one or more executable instructions that, when executed by one or more processors, cause the one or more processors to:

receive highway addressable remote transducer (HART) device data of a HART slave device via a PROFIBUS slave;

identify a device description (DD) file associated with the HART slave device using the HART device identification; and

perform one or more device communication functions with the HART slave device.

17. The non-transitory, computer-readable medium of claim 16, wherein the one or more executable instructions, when executed by the one or more processors, further cause the one or more processors to exchange identification data before configuring information from the HART slave device.

18. The non-transitory, computer-readable medium of claim 16, wherein the one or more device communication functions comprise at least one of:

opening a device data port (DP (V1)) connection to the HART slave device;

or

sending one or more initialization DP (V1) write/retry/read commands via PROFIBUS slave devices.
