Abstract

A system tag identifying a device of a process control loop is determined/derived from a unique identifier of the device while the loop is communicatively disconnected from a process plant's back-end environment or control room. The system tag may be stored at the device itself or at a proxy that is disposed in the field of the process plant (e.g., at another component of the loop). One or more commissioning activities that include the device are performed in the field using the device's system tag, and at least some of the field commissioning activities may be automatically triggered based on the derivation of system tag. Upon the loop being communicatively connected to the back-end environment of the plant, the device's system tag known to the loop in the field is synchronized with the device's system tag known to the back-end of the process plant.

First claim

What is claimed:

1. A method of commissioning a process plant, the process plant having a field environment and a back-end environment, and the method comprising:
obtaining, by one or more computing devices disposed in the field environment of the process plant, a first source tag of a physical field device disposed in the field environment of the process plant while the physical field device is in an input-output (I/O)-unallocated state,
the first source tag identifying the physical field device,
the physical field device to, during run-time of the process plant, perform a physical function and at least one of send or receive, via an I/O device, data corresponding to the physical function to control an industrial process executing in the process plant, and
the I/O-unallocated state of the physical field device indicative of the physical field device being unassigned to communicate via any I/O device;

deriving, by the one or more field environment computing devices, based on (i) a first instance of a set of parsing rules that is accessible to the one or more field environment computing devices and (ii) the first source tag, a first system tag that logically identifies the physical field device, the first system tag having a total number of characters different than a total number of characters of the first source tag;
storing the first system tag logically identifying the physical field device in a memory disposed in the field environment of the process plant;
automatically initiating, by the one or more field environment computing devices, one or more commissioning actions at the physical field device in the process plant using the first system tag that logically identifies the physical field device while the physical field device is in the I/O-unallocated state; and
subsequent to automatically initiating the one or more commissioning actions at the physical field device:
detecting that the physical field device is in an I/O-allocated state, the I/O-allocated state indicative of the physical field device being assigned to communicate via a particular I/O card;
based on the detection of the physical field device being in the I/O-allocated state, comparing the first system tag of the physical field device stored in the memory disposed in the field environment of the process plant with a second system tag of the physical field device stored in a memory disposed in the back-end environment of the process plant, the second system tag derived or obtained, by one or more computing devices disposed in the back-end environment of the process plant, based on a second instance of the set of parsing rules and a second source tag identifying the physical field device that are accessible to the one or more computing devices disposed in the back-end environment of the process plant; and
sending an alert to a user interface when the first system tag and the second system tag corresponding to the physical field device do not match.

2. The method of claim 1 , wherein obtaining the first source tag of the physical field device comprises obtaining the first source tag of the physical field device from an asset management system of the process plant.

3. The method of claim 1 , wherein obtaining the first source tag of the physical field device comprises obtaining a source tag of the physical field device having a particular format, the particular format based on a user indication.

4. The method of claim 1 , wherein obtaining, by the one or more field environment computing devices, the first source tag of the physical field device comprises using an optical interface of the one or more field environment computing devices to scan or read the first source tag of the physical field device.

5. The method of claim 1 , wherein obtaining the first source tag of the physical field device comprises obtaining the first source tag from a memory of the physical field device.

6. The method of claim 1 , wherein obtaining the first source tag of the physical field device comprises obtaining a unique identifier of the physical field device, the unique identifier being in accordance with the HART communication protocol, the WirelessHART communication protocol, or another industrial communication protocol.

7. The method of claim 6 , wherein obtaining the unique identifier of the physical field device comprises:
obtaining a long tag of the physical field device, wherein the total number of characters of the system tag is less than the total number of characters of the long tag; or
obtaining a short tag of the physical field device, wherein the total number of characters of the system tag is greater than the total number of characters of the short tag.

8. The method of claim 1 , wherein determining the first system tag of the physical field device comprises determining at least one of a control tag, a device tag, or a device signal tag corresponding to the physical field device.

9. The method of claim 1 , wherein deriving the first system tag from the first source tag based on the first instance of the set of parsing rules comprises determining the first system tag based on at least one of a truncation of the first source tag, a deletion of one or more characters from the first source tag, an addition of one or more characters to the first source tag, a combination or manipulation of at least some of the numerical characters included in the first source tag, or another technique for modifying a length of the first source tag.

10. The method of claim 1 , further comprising configuring the set of parsing rules.

11. The method of claim 1 , wherein the one or more commissioning actions using the first system tag of the physical field device while the physical field device is in the I/O-unallocated state includes at least one of:
an automatic generation, using the first system tag of the physical field device, of an as-built I/O list, the as-built I/O list indicating a portion of a process control loop that includes the physical field device and that has been built in the field environment of the process plant, the I/O as-built list for use in one or more other commissioning actions; or
an automatic generation, using the first system tag of the physical field device, of an as-built loop diagram, the as-built loop map descriptive of the portion of the process control loop including the physical field device that has been built in the field environment of the process plant, and the as-built loop diagram for use during a loop check or test of the process control loop.

12. The method of claim 1 , further comprising providing the first system tag of the physical field device to another device disposed in the field environment of the process plant to be used in performing another commissioning action including the physical field device and the another device while the physical field device is in the I/O-unallocated state.

13. A system for commissioning a process plant having a field environment and a back-end environment, the system comprising:
a physical field device in an input-output (I/O)-unallocated state and disposed in the field environment of the process plant,
the physical field device to, during run-time of the process plant, perform a physical function and at least one of send or receive, via a port and an I/O device, data corresponding to the physical function to control a process executing in the process plant, and
the I/O-unallocated state of the physical field device indicative of the physical field device being unassigned to communicate via any I/O device; and

one or more processors disposed in the field environment of the process plant and executing a set of computer-executable in
