Technologies
The stack, layer by layer
Organised by ISA-95, because that is the vocabulary the work actually uses. The most expensive mistakes in modernization come from solving a problem at the wrong level of the stack.
Level 1-2
Controls: PLC, HMI, IPC
The layer everything else depends on. Platform selection, migration off obsolete controllers, code standards, and whether what gets installed is supportable after the integrator leaves.
Rockwell Automation (Allen-Bradley) · Siemens
Level 2-3
SCADA and Historians
Supervisory systems and the historians behind them. Architecture, tag standards, redundancy, and the difference between a system operations trust and one they work around.
Inductive Automation (Ignition)
Level 3
MES and Batch
Order execution, traceability, genealogy and electronic records. Usually the most over-scoped project in a plant, and the one most often justified after the fact.
MES platforms · batch and recipe management
Level 3-4
OT Networks and Segmentation
Physical layer, addressing, segmentation and the security boundary between plant and enterprise. The layer blamed for everything and instrumented for nothing.
Industrial Ethernet · Phoenix Contact · managed switching
Level 4
Plant Data and Integration
Getting trustworthy data off the floor and into systems that act on it. Tag standardisation, contextualisation, and the unglamorous work that makes analytics possible.
MQTT Sparkplug · OPC UA · historians · ERP integration
Level 0-1
Edge and I/O
Field devices, edge controllers and machine vision. Increasingly where data acquisition happens without touching the control system at all.
Opto 22 · Banner Engineering · Cognex
Naming a platform is not endorsing it. This page states capability. Vendor-independent, but not opinion-neutral: when one platform is better for a given situation, we say which and why. See Partners for relationship disclosures.
Core technologies
The platforms we work on most
Grouped by the layer they sit at, because that is what decides whether a platform is the right answer. Capability, not partnership — every commercial relationship is disclosed on Partners.
Level 1-2
Control platforms
The controllers the plant runs on. Most of our work here is migration off obsolete hardware and holding new code to a standard the plant can still support in ten years.
Rockwell Automation
PLC, HMI and drives
ControlLogix, CompactLogix and Studio 5000 on migration, code standards and design review before commissioning.
Siemens
PLC and industrial software
SIMATIC controllers and TIA Portal on greenfield and migration work where Siemens is the plant standard.
Level 0-1 · 3-4
Edge, I/O and OT networks
Where data now gets acquired without opening the control system, and the network layer that gets blamed for everything and instrumented for nothing.
Opto 22
Edge controllers and remote I/O
groov EPIC and groov RIO for edge data acquisition and MQTT publishing alongside an existing control system rather than through it.
Phoenix Contact
Networking, I/O and panel
Managed switching, industrial networking and PLCnext, most often on OT network architecture and segmentation work.
Level 2-3
Supervisory software and computing
The systems operations either trust or work around. Architecture, tag standards and redundancy decide which one you end up with.
Inductive Automation
SCADA, historian and MES
Ignition architecture, tag standards, historian design and MQTT Sparkplug over a unified namespace.
Teguar
Industrial computing
Panel PCs and industrial hardware specified into plant-floor and machine-side deployments where commercial hardware will not survive the environment.
Level 0-1
Sensing, vision and motion
Inspection, identification and the sensing that quality data depends on. The layer that decides whether a traceability project has anything real to record.
Omron
Sensing, safety and motion
Sensing, safety devices and machine control on packaging and assembly equipment where Omron is the OEM standard.
Cognex
Machine vision and ID
In-Sight vision and barcode reading for inspection, date-code verification and the read rates traceability actually depends on.
