10 Tips for Choosing Industrial Automation Solutions

Selecting industrial automation solutions is not simply a matter of comparing product prices or counting features. It is a practical decision that affects production quality, worker safety, maintenance time, and long-term business performance. A suitable system should match the plant’s processes, equipment, workforce, and future plans.

Real-world experience shows that small details often determine success. A controller may perform well in a demonstration, yet struggle with dust, vibration, heat, or unstable network conditions on the factory floor. Integration also matters. An automation platform must communicate reliably with existing sensors, drives, robots, and enterprise software. Otherwise, operators may face isolated data and slower troubleshooting.

No solution is perfect.

This guide presents ten practical tips for evaluating automation technologies with greater confidence. It considers technical capability, supplier expertise, cybersecurity, scalability, training, service response, and measurable return on investment. A reliable vendor should explain limitations clearly, provide relevant case studies, and support testing before full deployment. Claims should be checked against maintenance records, production data, and feedback from actual users.

The selection process may still involve uncertainty. Budget forecasts can change, integration problems can appear late, and staff adoption may take longer than expected. That is why a phased pilot often provides stronger evidence than an ambitious installation across the entire plant. Careful questioning, site-specific testing, and honest risk assessment can prevent expensive surprises. The best industrial automation solutions are not always the most advanced. They are the ones that deliver dependable results under real operating conditions.

Define Automation Goals with OEE, Downtime, and ROI Baselines

Before choosing industrial automation solutions, define what improvement means on your production floor. Record OEE for each critical line over several normal weeks. Split it into availability, performance, and quality. A monthly average can hide painful shifts. Track planned stops, microstoppages, changeovers, scrap, and rework. Use machine logs and operator observations together. The numbers may disagree. That is useful.

Establish downtime baselines by cause, duration, and lost output. A ten-minute sensor fault deserves different attention from a two-hour material delay. Ask operators to mark recurring stops during specific shifts. Their notes often reveal issues hidden in dashboards. For ROI, calculate current labor hours, scrap costs, maintenance spending, and the value of lost throughput. Include integration, training, maintenance, and downtime during installation. A fast payback estimate can still be wrong.

Treat every baseline as working evidence, not permanent truth. Data quality is often weak. A line may show strong OEE while producing excessive rework. Pilot the solution on one bottleneck and compare similar products, shifts, and staffing levels. Review results after 30, 60, and 90 days. If gains depend on constant operator intervention, the design needs reconsideration. Leave room to challenge the original assumptions.

Benchmark Capacity Against IFR’s 151 Robots per 10,000 Workers

Choosing an industrial automation solution starts with a realistic capacity benchmark. The International Federation of Robotics reported 151 operational robots per 10,000 manufacturing employees worldwide in 2022. That benchmark is useful, but it is not a universal target. The 2024 edition recorded 162 robots per 10,000 employees for 2023. The increase shows stronger automation adoption, not guaranteed productivity.

Use the figure as a screening question. A plant running two shifts may need more automation than a single-shift facility. For example, a palletizing cell handling 40 cartons per minute needs different equipment from a small machining line. During a site assessment, record cycle time, changeover duration, operator walking distance, and unplanned stops. Watch the bottleneck. A seven-minute changeover may matter more than adding another robot.

Capacity alone can mislead. The World Economic Forum’s Future of Jobs Report 2023 estimates that 44% of workers’ core skills may change by 2027. Training, maintenance capability, and process data deserve equal attention. A robot may be technically fast but operationally weak when fixtures drift or sensors fail. I would challenge any proposal that compares robot density without checking product mix and uptime. The 151 figure is a useful reference, yet it remains imperfect. Your factory should explain the gap.

Global industrial robot density increased from 85 to 151 robots per 10,000 workers between 2017 and 2022. The 151-robot benchmark can help organizations assess whether their planned automation capacity is below, near, or above the global manufacturing average.

Evaluate Interoperability Through ISA-95, OPC UA, and Open APIs

Choosing industrial automation solutions requires more than checking performance figures. In practical plant assessments, ISA-95 helps clarify responsibilities between enterprise, operations, control, and field levels. Map each data flow before comparing products. A clean diagram can still hide unclear ownership. Tip: Ask where production orders become machine instructions, and who validates that exchange.

OPC UA should be evaluated as an information model, not merely a connection method. Check whether equipment exposes meaningful tags, alarms, units, timestamps, and status values. Test read and write permissions with realistic production scenarios. Tip: Request a live demonstration using a simulated stoppage, not a prepared slide. Small details matter.

Open APIs support reporting, scheduling, maintenance, and future integration. Review documentation, authentication methods, rate limits, version policies, and error messages. An API that works during a pilot may struggle under shift-level traffic. Measure response times. Test failure recovery. Tip: Build a small proof of concept with one line and one historian. Do not trust perfect test data. Some interoperability gaps only appear after weeks of changing recipes, incomplete signals, and revised user roles. Teams should record these failures instead of quietly working around them. A workaround may be practical today, but it can become tomorrow’s dependency.

10 Tips for Choosing Industrial Automation Solutions - Evaluate Interoperability Through ISA-95, OPC UA, and Open APIs

No. Evaluation Tip Relevant Interoperability Area What to Verify Practical Acceptance Criterion Business Value
1 Map the solution to ISA-95 levels ISA-95 enterprise-control system hierarchy Identify whether the solution operates at Level 0–2 control, Level 3 manufacturing operations, or Level 4 business planning. The supplier provides a clear system boundary and documented interfaces between adjacent ISA-95 levels. Reduces architectural overlap and integration gaps.
2 Check ISA-95 object-model alignment Personnel, equipment, material, process segment, and production schedule models Review how production orders, equipment structures, materials, capabilities, and performance data are represented. Core objects can be mapped without relying on undocumented custom fields. Improves consistency between manufacturing and enterprise applications.
3 Confirm OPC UA information modeling OPC UA structured information models Determine whether the solution exposes typed objects, variables, methods, relationships, units, and engineering metadata. A documented namespace and companion information model are available for the required equipment and processes. Preserves context instead of exposing only unstructured tags.
4 Evaluate OPC UA security controls Certificates, application authentication, encryption, signing, and user authorization Review certificate management, security policies, trust lists, role-based access, and security-event handling. Production communication uses authenticated and encrypted channels with documented certificate rotation procedures. Protects operational data while supporting controlled access.
5 Test real-time data behavior OPC UA subscriptions, monitored items, timestamps, status codes, and deadbands Measure update behavior, quality indicators, source and server timestamps, queue handling, and reconnect behavior. Required process values retain timestamps and quality status during normal operation and network recovery. Supports reliable monitoring, alarms, and performance analysis.
6 Assess support for scalable OPC UA communication Client/server and publish/subscribe communication patterns Check whether the solution supports the communication pattern needed for centralized applications, distributed consumers, or event-driven data distribution. The architecture remains functional when additional consumers, sites, or production assets are added. Improves scalability without creating point-to-point connections.
7 Review the Open API contract REST or equivalent web APIs, resource models, JSON schemas, and versioning Request machine-readable API documentation, endpoint definitions, data schemas, error responses, and version policies. An external application can discover and call documented endpoints without proprietary middleware. Reduces custom integration effort and improves maintainability.
8 Verify API identity and access management API authentication, authorization, scopes, and auditability Check support for secure authentication, least-privilege permissions, token or credential expiration, and access logs. Read, write, administrative, and operational permissions can be separated and audited. Limits unauthorized changes and supports compliance reviews.
9 Test data semantics and units ISA-95 terminology, OPC UA metadata, engineering units, time zones, and identifiers Compare equipment names, material codes, quantities, units, status values, timestamps, and reason codes across interfaces. The same business event has consistent meaning and measurement units in every connected system. Prevents incorrect analytics, reporting, and production decisions.
10 Run an end-to-end interoperability proof of concept ISA-95 workflow, OPC UA connectivity, and Open API integration Simulate a complete flow: production request, schedule release, execution update, quality result, and completion confirmation. The workflow completes with traceable identifiers, reliable acknowledgements, recoverable errors, and no undocumented manual steps. Validates integration risk before full-scale deployment.
Evaluation note: ISA-95 provides a reference structure for enterprise and manufacturing operations integration, OPC UA provides secure industrial communication and information modeling, and Open APIs provide application-level access for interoperable workflows.

Prioritize Safety and Cybersecurity with ISO 10218 and IEC 62443

Industrial automation choices now carry two risks: physical harm and digital disruption. The IFR World Robotics 2024 report recorded 541,302 industrial robot installations in 2023, with 4.28 million robots operating worldwide. More robots mean more motion, interfaces, credentials, and maintenance paths. Safety cannot remain a commissioning checklist. It must shape the cell before hardware arrives.

ISO 10218 provides a practical foundation for robot safety, including risk assessment, safeguarding, collaborative operation, and integration responsibilities. During a site review, inspect the gate switch, teach pendant, emergency stop, and reduced-speed mode. Ask what happens after power returns. A robot should not restart unexpectedly. That detail matters.

IEC 62443 adds a cyber layer through zones, conduits, security levels, and lifecycle roles. Separate robot cells from enterprise networks, restrict remote access, and log engineering changes. Use unique accounts and tested recovery copies. Air-gapped is not automatically secure.

IBM’s X-Force Threat Intelligence Index 2024 identified manufacturing as its most attacked sector, representing 25.7% of observed incidents. That figure should change procurement questions. Request a documented asset inventory, patch process, vulnerability disclosure route, and incident contact. Require suppliers to explain default credentials and support timelines.

Test controls with production owners, not paperwork alone. Teams often overestimate segmentation and underestimate human access. A common site finding is a locked controller cabinet beside an exposed maintenance laptop.

The uncomfortable lesson is simple: compliance evidence can look complete while protection remains weak. Review ISO 10218 and IEC 62443 together, then verify every claim on the shop floor.

Compare Total Cost, Payback, MTBF, and Ten-Year Support Value

Choosing industrial automation solutions requires more than comparing purchase prices. Total cost includes engineering, commissioning, operator training, energy use, spare parts, downtime, cybersecurity updates, and disposal.

The U.S. Department of Energy reports that motor-driven systems consume about 70% of industrial electricity in the United States. Even a small efficiency gain can therefore change the payback calculation.

For example, a $180,000 project producing $50,000 in annual savings has a simple payback of 3.6 years.

The number looked attractive, but it ignored production losses during installation.

MTBF is useful, but it is not uptime. A high MTBF with slow repair can still create costly interruptions. Review MTBF together with mean time to repair, diagnostic quality, spare availability, and local technical skills.

ARC Advisory Group’s industrial automation outlooks repeatedly emphasize lifecycle economics and service capability, not only initial investment.

Ten-year support should include documented firmware policies, replaceable components, migration paths, training, and response commitments. Ask for evidence from comparable operating environments. Do not accept a generic “supported for ten years” statement.

Support terms can be vague. A stronger evaluation models yearly service costs, expected downtime, and component obsolescence under conservative assumptions.

Some estimates will be imperfect, and that is acceptable. Transparent uncertainty is safer than false precision.
