Image Modified P1:Unified Namespace (

UNS) Module OverviewThe Unified Namespace Module

Concept) is the first pillar on the Four Pillars methodology, it provides a centralized real-time data repository with hierarchical organization for all solution data.

It

As the first pillar in the Four-Pillar methodology, it creates a standardized method for accessing and managing tags, assets, and external data sources

through a single, cohesive framework that serves as the foundation for all other modules

Key Concepts

Concept	Description	Example
Tag

:

Process variable representing real-time and historical data

, created locally or accessed remotely

	Tank01.Level, Pump01.Status
Asset Tree

:

Hierarchical representation of solution data

containing variables and DataTemplatesDataTemplate

	/Plant/Area1/Line1/Equipment
UserType (UDT)

: User-defined

Reusable data structure

including

with variables and references

to other templatesTagProvider Service:

	Motor template with Speed, Current, Status
TagProvider Services	Direct interaction with variables in remote systems

Enumeration:

OPC UA server, MQTT broker connections
Enumeration	Named integer values

representing discrete options or states

with

associated

messages and colors	0=Stopped, 1=Running, 2=Fault
Runtime Database

:

In-memory real-time database managing UNS data

TServer.exe process

What the UNS Does

The Unified Namespace

data during solution execution

serves as your solution's data backbone:

Data Organization	System Integration
Creates

What It Does

Creates and manages

real-time data models with tags

,

and templates

, and enumerations

Organizes data in hierarchical Asset Tree structure

with folders and templates

Maintains relationships between equipment and data
Provides intuitive navigation through process hierarchy

Enables dynamic connectivity to external systems

through TagProvider connections

Supports advanced data types including SQL

types, .NET entities, and complete DataTables

datasets and JSON objects
Provides type-safe references and up to tri-dimensional arrays

Provides tri-dimensional dynamic arrays and type-safe reference tags

Maintains event-driven, in-memory database

for real-time data exchange

Info

title	DataExplorer: Accelerating UNS Development

The DataExplorer tool streamlines UNS creation by enabling:

Discovery - Browse MQTT brokers, OPC servers, PLCs, and SQL databases
Import - Create tags and templates directly from discovered structures
Validate - Test connections before adding to production

Image Added

This tool reduces manual configuration time by 50-70% when building your tag structure during the Foundation phase.

Runtime Behavior

Data Loading and Management

When solution execution starts, the Unified Namespace definition loads into the in-memory real-time database (TServer.exe process). This database enables event-driven data exchange between all solution modules with millisecond precision.

Data Access Methods

Modules access Unified Namespace variables through two primary methods:

Direct Tag Access (Local Tags)	Asset Method Access: Using the Asset() function
Using tag names

and paths

Example: Tag.Machine1.Temperature
Supports both local tags and nested

template properties

UserType properties

When connecting the tag with the field device

Use the Devices Module to map the Tag to a DevicePoint
If the protocol has TagDiscovery, you can use the DataLink field
- In this case only the TagProvider services must be enabled

Asset Method Access: Using the Asset() function

Example: Asset("/Line1/Machine1.Temperature")

Required for TagProvider connections and dynamic references

Tag vs TagProvider Connections

Aspect	Tags	TagProvider Connections
Definition	Local real-time variables within solution	Direct link to external system variables
Creation	Created and configured locally	Defined in remote system, linked dynamically
Data Mapping	Devices Module handles remote mapping	No local mapping required
Access Method	TagName or AssetPath	AssetPath only via Asset() method
Use Case	Core solution data requiring local control	Dynamic external data without local overhead

Local Tags can be also use this syntax

TagProvider TagDiscovery Service

If the protocol supports TagDiscovery (OPC UA, MQTT, ..)
- Dynamic Tags can created in runtime as a Asset("path") is used.

Common Implementation Patterns

ISA-95 Model Implementation

evel	Asset Structure	Typical Tags
Enterprise	/Company	KPIs, Financial metrics
Site	/Company/Site1	Production totals, Energy usage
Area	/Company/Site1/Area1	Area production, Quality metrics
Line	/Company/Site1/Area1/Line1	Line speed, Product counts
Cell	/Company/Site1/Area1/Line1/Cell1	Equipment status, Process values

Naming Convention Best Practices

Code Block

title	Naming Individual Tag Names

Standard Format: [Area]_[Equipment]_[Component]_[Signal]

Examples:
WTP_PUMP01_MOTOR_RUNNING
WTP_PUMP01_MOTOR_SPEED_SP
WTP_TANK01_LEVEL_PV
BLDG_HVAC_AHU01_TEMP_SP

if using UDT SP is BLDG_HVAC_AHU01_TEMP.SP

Code Block

title	Naming using Asset Folders and UDTs

Standard Format: [Area]/[Equipment]/[Component][Signal].[Attribute]

Examples:
WTP/PUMP01/MOTOR/RUNNING
WTP/PUMP01/MOTOR/SPEED.SP
WTP/TANK01/LEVEL.PV
BLDG/HVAC/AHU01/TEMP.SP

Code Block

title	Naming adding a DataTemplate for Components( MOTOR, TANK)

Standard Format: [Area]/[Equipment]/[ComponentUDT].[Signal]

Examples:
WTP/PUMP01/MOTOR.RUNNING
WTP/PUMP01/MOTOR.SPEED.SP
WTP/TANK01/LEVEL.PV
BLDG/HVAC/AHU01.TEMP.SP
