Unplanned equipment downtime
Failures are discovered when machines stop, causing lost production and emergency repairs.
02 / Automation
Plants already collect a great deal of data through PLCs, SCADA systems and sensors. Much of it is never used beyond the control room. We connect operational technology with IT systems and AI so that data informs maintenance, quality and production decisions, without compromising safety or control integrity.
At a glance
Durations depend on scope, data readiness and integration needs.
Short answer
Industrial automation is the use of control systems, sensors, software and increasingly AI to operate and monitor industrial processes and equipment. In our practice it focuses on connecting operational technology (OT) data with IT and analytics systems for monitoring, predictive maintenance, quality inspection and production optimisation.
Industrial environments are different from office IT. Equipment runs for decades, safety comes first, networks are segmented for good reason and downtime is expensive. Any AI or automation work has to respect those realities.
We typically work above the control layer. Rather than changing how PLCs control machines, we collect data from them through secure, read-only connections, contextualise it with maintenance, quality and production records, and build applications that help engineers and operators make better decisions.
Where closed-loop control is involved, changes follow your engineering change process and are validated by the plant's control engineers.
Business problems
These are the situations where organisations most often find this service worthwhile.
Failures are discovered when machines stop, causing lost production and emergency repairs.
Visual checks are slow, inconsistent between shifts and miss subtle defects.
PLC and SCADA data is available in the control room but not connected to planning or maintenance systems.
Inefficient settings and process drift increase energy use and scrap without anyone noticing quickly.
Logs, checklists and downtime reasons are recorded on paper or spreadsheets and rarely analysed.
Troubleshooting depends on experienced engineers whose knowledge is not captured.
Use cases
Representative applications. The right use case depends on your processes, data and constraints.
| Area | Example application |
|---|---|
| Maintenance | Condition monitoring from vibration, temperature and current data with early warning of degradation. |
| Quality | Camera-based inspection for surface defects, dimensions and assembly completeness. |
| Production | OEE tracking, downtime reason capture and bottleneck analysis across lines. |
| Energy | Energy monitoring by line or asset with anomaly detection for unusual consumption. |
| Process industries | Soft sensors that estimate hard-to-measure quality parameters from process variables. |
| Safety | Vision-based detection of safety zone breaches and personal protective equipment compliance, as an aid to existing controls. |
How AARHIT approaches it
Each stage ends with something you can review, so decisions are made on evidence rather than on promises.
Stage 1 of 6
We review equipment, control systems, networks, existing data, maintenance records and the problems that matter most to plant leadership.
Output: assessment report with data availability, security considerations and ranked use cases.
Stage 2 of 6
We design secure data collection, typically read-only through gateways, with appropriate network segmentation and a data model for assets and events.
Output: architecture approved by plant engineering and IT security.
Stage 3 of 6
Sensor and control data is collected, time-aligned and linked with maintenance logs, quality results and production schedules.
Output: a contextualised data foundation for the pilot area.
Stage 4 of 6
Analytics, anomaly detection or vision models are developed with engineers, then wrapped in dashboards, alerts or inspection stations.
Output: working pilot on selected equipment or a line.
Stage 5 of 6
The pilot runs under real conditions. Alerts and predictions are reviewed with maintenance and quality teams to confirm usefulness.
Output: validation results and a scale-up recommendation.
Stage 6 of 6
Proven solutions are extended to more assets or lines, with model monitoring and ownership assigned inside the plant.
Output: rollout plan, runbooks and training.
Technology
We choose tools on fit, cost, security and your existing estate. These are typical options, not fixed commitments.

Outcomes
Targets are agreed with you during scoping and measured against a baseline. We do not quote improvement figures before we have seen your process and data.
Typical timeline
An assessment typically takes 4 to 6 weeks including site visits. Condition monitoring or vision inspection pilots commonly run 8 to 16 weeks, since they need enough operating time to observe meaningful events. Scale-up is planned line by line or asset class by asset class.
Implementation
Most difficulties in this kind of work are predictable. Planning for them early keeps delivery on track.
Data collection should not interfere with control systems. Read-only access and segmented networks are the default.
Well-maintained assets fail rarely. Anomaly detection and physics-informed approaches often work better than pure failure prediction at the start.
Cameras and sensors need suitable enclosures, mounting, lighting and maintenance plans.
Alerts only help if operators and technicians trust and act on them, so they must be part of design and validation.
| Risk to consider | How we manage it |
|---|---|
| Interference with safe operations | Read-only integration, engineering change approval and validation by plant control engineers. |
| Cybersecurity exposure of OT networks | Segmentation, secure gateways, access controls and monitoring agreed with IT and OT security. |
| Alert fatigue | Tuned thresholds, prioritised alerts and feedback from technicians to reduce false alarms. |
| Pilot results that do not scale | Standardised data models and deployment patterns designed from the pilot stage. |
FAQ
Often yes. Older equipment can be fitted with external sensors for vibration, temperature or current, and data can be read from existing PLCs through gateways without replacing the machine.
Any connection must be designed with security in mind. We use read-only data paths, network segmentation, secure gateways and access controls, and we work with your IT and OT security teams to approve the design.
Condition monitoring tracks the health of equipment and alerts when readings look abnormal. Predictive maintenance goes further by estimating when a failure is likely, which needs more history. Many programmes start with condition monitoring.
No. Many useful applications, such as anomaly detection or vision inspection, work without one. A digital twin becomes valuable when you need simulation or a unified model of a complex asset or process.
We collaborate with system integrators and equipment vendors, respect their warranties and control responsibilities, and focus on the data, analytics and application layers above control.
