Assess & stabilize
Baseline the installed base, interfaces, failure modes, data sources and success criteria. Fix the reliability and documentation gaps that block any modernization before adding new layers.
Modernization & IIoT
Modernize today. Built for the next decade.
Many productive lines still run on controls installed ten or twenty years ago. AranVision helps you bridge that installed base toward IIoT- and AI-ready operations in stages that respect production—so you gain data, diagnostics and resilience without a risky rip-and-replace.
Where operations are heading
The direction of industrial automation, 2026 and beyond.
These are options to evaluate against the installed system, available evidence and project requirements. They are not capabilities guaranteed by every device or a promise of a specific operational improvement.
- Maintenance is moving from predictive to prescriptive. Condition monitoring can combine several signal types with edge analytics to flag anomalies and, where the data and model have been validated, suggest checks or corrective actions. A recommendation is not proof of root cause; your maintenance process and authorized people decide what happens next.
- Industrial AI is moving from advice to execution. AI tools can support defined diagnostic and documentation workflows. Any execution needs an explicit scope, approved interfaces and verification; an assistant must not be treated as a safety function or an approval authority.
- Data and intelligence are moving to the edge. An appropriately selected and configured gateway can buffer, normalize and process data near the machine. Storage limits, timestamps, stale-data indication and reconnect behaviour need verification before dashboards or digital-twin views rely on the data.
- Intelligence is moving into the devices. IO-Link provides device identification, parameters and diagnostics. Available measurements and warnings depend on the sensor and its IODD. Automatic parameter restore requires compatible replacement hardware and correctly configured data storage; commissioning benefits must be verified for the application.
- Interoperability is standardizing. OPC UA and MQTT can support data exchange across an agreed OT/IT boundary. Endpoints, information models, security and delivery requirements still need integration. Deterministic timing requires an appropriate network design and configuration; selecting a protocol alone does not establish it.
- “Self-healing” today means resilient, not autonomous. A resilience plan may include local buffering, failover, a defined restart policy and guided remediation. Each feature needs a supported architecture and tested failure/recovery conditions. Automatic recovery must not bypass permissives, interlocks or the project’s approval process.

A staged path
Four steps that respect production.
Connect
Expose data without ripping out working controls: add edge gateways, IO-Link masters and OPC UA/MQTT publishing to the existing PLCs and instruments, with secure OT/IT separation.
See
Turn the connected data into condition monitoring, dashboards and digital-twin views that operators and engineers actually use, with alerting tied to real operating thresholds.
Predict, then prescribe
Grow from condition-based to predictive and, where it is justified, prescriptive guidance—always with human-authorized actions and a maintainable handover, not a black box.

Retrofit, not rip-and-replace
Add capability to the line you already run.
Modernization earns its keep when it protects uptime. The usual first move is to make the existing controls observable—edge gateways alongside the current PLCs, IO-Link at the sensor layer, and OPC UA or MQTT publishing to a supervised OT/IT boundary—so data and diagnostics arrive before any hardware is disturbed.
From there, condition monitoring and digital-twin views are built on real signals, and predictive or prescriptive maintenance is introduced only where the data and the payback support it. Every step is scoped, tested and documented for handover.
AranVision works across Siemens, Rockwell, Beckhoff, Schneider and supervisory platforms, and recommends what fits your installed base—not a single brand. Controls software, integration, data connectivity and commissioning are delivered directly; regulated professional engineering, safety-function certification and required approvals are assigned to the appropriately licensed or authorized party before that work proceeds.
Modernization FAQ
Practical answers.
Do I have to replace my PLCs to get IIoT data?
Not always. Start by checking the installed controller, available interfaces, vendor support, security requirements and required data. A compatible gateway or interface may preserve working controls; replacement may be needed when support, performance or risk requirements cannot be met.
Is “self-healing” automation real?
The useful question is which failure and recovery behaviours can be tested on your system. Buffering, failover or a supervised restart may be appropriate. Neither an AI tool nor the phrase “self-healing” establishes safe recovery or authorizes an automatic restart.
Will AI agents control my process directly?
Only within explicit, human-authorized boundaries. Safety functions, interlocks and regulated approvals stay with the responsible licensed or authorized party. AI and analytics support decisions; they do not quietly take over control.
How does a modernization engagement start?
With a scoped assessment of the installed base, data sources, interfaces and goals. That produces a staged plan with clear responsibilities, so you can modernize in verifiable steps instead of one high-risk change.
