Standard code libraries
Reusable Add-On Instructions, user-defined types, and function blocks with consistent naming, so every new machine looks and behaves like the last.
Scalability
Built to scale: from one machine to plant-wide and global
Start small without painting yourself into a corner. We design controls so a single machine or line can grow into plant-wide systems and multi-site standards, connected to SCADA, MES, and ERP when you’re ready.
Methods
How we design for growth
The choices made on the first project decide how easily the tenth one goes.
ISA-88 / ISA-95 aligned structure
Code and data organized by site, area, line, and unit, so new units and lines slot in without restructuring.
Modular hardware & remote I/O
Distributed I/O and modular panels that let you add equipment where it lives instead of rewiring back to one cabinet.
Spare capacity planned in
Room for growth in I/O, panel space, power, network ports, and controller memory, sized for the next phase, not just today.
Platforms with headroom
Controller families that scale in the same engineering environment, such as CompactLogix to ControlLogix in Studio 5000, or S7-1200 to S7-1500 in TIA Portal.
Network architecture
Segmented networks with managed switches and VLANs, designed with the Purdue model and ISA/IEC 62443 zones and conduits in mind.
Standard HMI templates & faceplates
Consistent screens and device faceplates, so operators and maintenance recognize every line.
Data model planned for growth
A tag namespace and data model ready for plant-wide data, using OPC UA or MQTT with Sparkplug B and the Unified Namespace concept where it fits. Wide-area sensors can join over LoRaWAN.
Version control & change management
Program versions tracked and changes controlled, so you always know what is running and what changed.
Documentation & as-builts
Drawings, network diagrams, and I/O lists kept current, so the next expansion starts from accurate information.
Template-driven rollout
Proven designs copied, configured, and commissioned on additional lines or sites, with less re-engineering each time.
Architecture
Where each system fits
Control, operations, and business systems each have a level. Designing to that structure keeps integrations clean and secure.
Level 4ERP: orders, inventory, planning
DMZControlled boundary between plant and business networks
Level 3MES & historian: operations, quality, records
Level 2PLC, HMI & SCADA: supervision and control
Levels 0–1Field devices, sensors, drives & I/O
SCADA
SCADA, historians & alarming
Site SCADA & HMI
Operator visualization and control for a line or plant, with platforms such as Ignition, FactoryTalk View SE or FactoryTalk Optix, WinCC and WinCC Unified, or AVEVA.
Historians
Time-series storage of process values for trends, troubleshooting, and reporting, such as FactoryTalk Historian, AVEVA PI, Canary, or the Ignition historian.
Alarming
Centralized, prioritized alarms with acknowledgement, shelving, and notification, aligned with ISA-18.2.
Redundancy
Redundant servers, controllers, or networks where downtime is costly, so one failure doesn’t stop visibility or control.
Multi-site & enterprise
Central or hub-and-spoke architectures that roll up many sites, hosted on site, at the edge, or in the cloud.
MES
MES integration
What MES covers
Production orders, scheduling and dispatch, OEE, quality, genealogy and traceability, electronic batch records, labor, and maintenance: the ISA-95 Level 3 functions that sit between control and business systems.
How we integrate
OPC UA and MQTT for live data, SQL tables and stored procedures for transactions, REST APIs, and ISA-95 B2MML messages for orders and results.
Platforms
Systems such as Rockwell FactoryTalk ProductionCentre and Plex, Siemens Opcenter, AVEVA MES, and Ignition with Sepasoft modules. We connect controls to the MES you choose.
ERP
ERP integration
Systems
SAP (for example through SAP Plant Connectivity or Digital Manufacturing), Oracle, Microsoft Dynamics, Epicor, and NetSuite.
What flows
Work orders and material masters down to the floor; production counts, material consumption, and inventory back up to the business.
Done the right way
Through MES or an integration layer rather than PLC-to-ERP directly, with data validation and store-and-forward buffering so a network outage doesn’t lose records.
Global
Global solutions
Multi-site standards
One set of code, HMI, and network standards applied across plants, so support and spare parts are shared.
Localization
HMI languages and engineering units switchable per site, built in from the start.
Time zones
Timestamps and reports handled consistently across sites in different time zones.
Regional standards
Designs that account for UL and CSA requirements in North America and IEC and CE requirements in Europe from the beginning.
Central remote support
Secure remote access with controlled user permissions, so experts can help any site without travel.
Would you like to know more? Unified Namespace, OPC UA, and MQTT in brief
Unified Namespace vs point-to-point
Point-to-point integrations connect each system directly to each other system, which multiplies connections as you grow. A Unified Namespace (UNS) publishes plant data into one organized, event-driven structure (often by enterprise, site, area, and line) that every system can subscribe to, so adding a new consumer doesn’t mean new links to every PLC.
OPC UA vs MQTT
OPC UA is an industrial client/server (and pub/sub) standard with rich information models and built-in security, well suited to connecting controllers, SCADA, and MES. MQTT is a lightweight publish/subscribe protocol through a broker; with Sparkplug B it adds a defined payload and device state awareness, which suits plant-wide and cloud data distribution. Many architectures use both: OPC UA near the equipment, MQTT for distribution.
