Approach

Process thinking first. Technology second.

ISA-95 is a language standard. We use it to give operations, engineering, automation, IT and business one shared picture of the factory.

From process to equipment

We first model what the factory does (the process model), then translate it into what it is built from (the equipment model). Both share the same work center structure.

A library of ±60 process operations

Built on the unit operation concept that founded chemical engineering at MIT in 1920. Mixing, heat treatment, separation, drying, storage — every factory is a combination of these.

A 2-tier hierarchy

An enterprise hierarchy (top-down, organisational) and a site hierarchy (bottom-up, physical), meeting at the site — which ISA-95 calls a Site and SAP calls a Plant.

TAG coding without touching the field

The IT/OT hierarchy is prefixed to existing field tags. Engineering keeps its instrument codes; data gets full context for your historian and UNS.

Connecting all five layers

From devices and PLCs through SCADA and MOMS up to ERP: one shared language between signals, data, reports and information.

The Anatomy of a TAG

One tag structure, every site, one data lake. Each part of the tag has exactly one meaning and one fixed format, so "all baking lines across all sites" becomes a single query.

NIX.PPN.1RWH_TRD01_PST01_FT101-01

01 · AAA
NIX
Site
Mandatory in the data lake. One corporate list of unique 3-letter site codes.
02 · AAA
PPN
Plant
Plant within the site. Joined to the site with a dot.
03 · nAAA
1RWH
Area
Area number 1–9 + 3-letter code. Same meaning at every site.
04 · AAAnn
TRD01
Work Center / Unit
Standard work-center types, numbered 01–99.
05 · AAAnn
PST01
Equipment
Equipment module within the unit. Copy-paste units keep their structure.
06 · ISA 5.1 + nnn
FT101
Instrument
ISA 5.1 function letters, 100-number range per Work Unit.
07 · -nn
-01
Component
Optional, for replaceable parts and spares.

Six rules that make it scale

Two forms, one tag

Short form on drawings and in the control system; full form with SITE.PLANT. added automatically when data leaves the plant.

Fixed separators

Dot for the site prefix, underscore inside the plant, slash generated for UNS topics.

Equipment ≠ process

Equipment tags and process-step codes live in separate code lists, never mixed.

No enterprise in the tag

The enterprise is always the same in one data lake; it lives in the UNS root.

Three automatic checks

Every tag is unique, follows the format, and has an existing parent.

Publish as UNS

Final step: each tag becomes a topic, e.g. enterprise/nix/ppn/1rwh/trd01/pst01/ft101.

ERP meets Level 3

Business processes on the equipment model

Administrative ERP processes only become reliable when they are anchored to the physical factory. We map your global business processes onto the ISA-95 equipment hierarchy and process segment model, so finance, planning, maintenance and quality all speak the same structure as the shop floor.

Order to Cash

· Sales Order Process
· Pick, Pack & Dispatch
· Customer Complaints
· Cash Collection

Demand to Supply

· S&OP
· Master Production Scheduling
· MRP
· Shopfloor Material Staging

Plant Maintenance

· Asset Master Data
· Maintenance Planning
· Work Order Scheduling
· Spare Parts Inventory

Quality

· Inspection Lots
· Usage Decision
· Non-Conformance
· Final Product Release

Finance to Manage

· Cost Center Postings
· Product Costing
· Fixed Assets
· Period-End Close

Where each process lands

ISA-95 level	Tag	ERP object	Business processes
Enterprise	NIX	Company code / legal entity	Consolidation, Chart of Accounts
Site	NIX.PPN	Plant	MRP, S&OP, Stock control
Area	…5BKF	Profit center / cost center group	Cost allocation, Reporting
Work Center	…5BKF_OVN01	Cost center + ERP work center	Production orders, Routings, Scheduling
Work Unit	…OVN01_TNL01	Fixed asset + functional location	Maintenance, Depreciation, CAPEX
Equipment Module	…TNL01_BRN01	Maintenance equipment / BOM	Notifications, Spare parts

Five ways we connect ERP and MOM

Link matrix

Every business process anchored to the ISA-95 level where it actually happens.

One tag, one key

The equipment tag doubles as cost object, asset number and maintenance location.

Process Segments as bridge

ERP routing steps become ISA-95 process segments, executed on Work Centers and Units.

Level 4 ↔ Level 3

Planning, order and cost in ERP; scheduling, execution and data collection in MOM.

Transactions as UNS events

Order start, inspection lot or maintenance notification published under the tag.
