In the engineering world, tag can mean many specific things. For example, in the design tools that make up the SmartPlant Enterprise environment, tag usually means a piece of equipment that will be placed in the plant. In SmartPlant Master Tag Registry, a tag is a composite of technical details about objects coming from the authoring tools and an object identification number, or tag number. For example, a tag created for an instrument object will have the tag number PI-1000 along with technical details, such as tag status, description, key engineering and references to import documents. The tag number and the technical details of the tags can be created, collected and managed with SmartPlant Master Tag Registry.
Tags in the authoring domain
SmartPlant Master Tag Registry includes an authoring domain for gathering tags and their data from vendors and for incorporating additional data on tags published by SmartPlant authoring tools. These tags can originate in SmartPlant Master Tag Registry to support engineering work processes where vendor tags are pre-allocated by an EPC. The technical data on the tags is provided by vendors in a Microsoft Excel data sheet and imported into the authoring domain.
The information about the tags can then be managed in the authoring environment until it is ready to be published to the published domain (MTRPublishing) and consolidated into the CDW domain with tag data from other SmartPlant Enterprise authoring tools. Once the tags are published and consolidated, you can create a tag register for handover. For more details on authoring and published domains, see How to Configure SmartPlant Foundation Authoring.
Tag naming
To create tags, first you must choose the tag type for which you want to create tags. Tag types are object types, such as instrument, cable, and equipment that categorize the tags. Each tag type is preconfigured with an ENS (Engineering Number System) definition that uses project-specific identification formats to automatically create names for the new tags.
The ENS definition is composed of various components, called ENS items, that can use constants and data extracted from other properties on the object or related objects. These components are configured in sequence with additional delimiter characters to define the required format. By default, SmartPlant Master Tag Registry delivers one ENS definition for each tag type. The following ENS definitions are delivered with the software:
-
MTRCableAuthoring
-
MTRElectricalAuthoring
-
MTREquipmentAuthoring
-
MTRInstrumentAuthoring
-
MTRPipingSpecialtyAuthoring
-
MTRValveAuthoring
The SmartPlant Foundation administrator can create and update the delivered ENS definitions,
create new definitions, or terminate the relationship between the existing ENS definition
and its associated class definition.
The delivered ENS definitions preconfigured for tag types use the following ENS item types:
-
Property - specifies the property definition.
-
ENS Function - automatically allocates a sequence number. Sequence defines the sequence of numbers to follow the ENS sequence start number.
For example, using the following settings, you could create the first cable tag with the name SC-1.
-
Property for the cable tag is SC
-
A ‘-‘(hyphen) set as a delimiter after the environment variables
-
Sequence number is set to start at 1
Only a SmartPlant Foundation administrator can configure and update the ENS definitions
for the tag types. For more information about configuring ENS, see Configure the Engineering Numbering System (ENS).
Allows you to create one or more tags in the MTRAuthoring domain.
Description - Allows you to enter a description for the tag.
Unit - Allows you to select a unit with which you want to associate the new tag.
System - Allows you to select a system with which you want to associate the tag.
Tag Status - Allows you to specify the status of the authoring tag.
Preliminary - Initial status of a tag set by the EPC when pre-allocating tags for a vendor.
Active - Status of a tag set by a vendor in the Microsoft Excel datasheet to indicate to the EPC which pre-allocated tags were used by the vendor.
Unused tags keep their Preliminary status and can be re-provisioned to other vendors
Void - Indicates that a previously used tag number is no longer required by the vendor.
Descoped - Indicates that the tag has been removed.
Supply Responsibility - Company that purchases an item for a project.
Vendor - Company that sells an item for a project.
Authoring Doc Proxies - Allows you to relate existing document proxies such as technical specification documents, drawings, commercial detail documents, warranty documents, and so on to a tag.
Number to create - Allows you to specify the number of tags to be created with the defined properties.
Start at number - Allows you to specify the starting sequence number for the tag or tags you are creating.
Because tag names are generated automatically using ENS, you cannot provide a name
for the new tag on this dialog box.
Class - Allows you to specify the class for an authoring tag.
