Buyers evaluating a functional safety partner for industrial control systems ask three things before they submit a form: Does the team understand IEC 61508 and the SIL allocation process, not just embedded engineering in general? Has it actually carried a control system through certification, not just designed one? And can it document the safety case an assessor will accept?
Embien engineers functional safety embedded control systems to industrial automation standards (IEC 61508) across the full V-model — hazard and risk analysis, SIL determination, safety-rated hardware and firmware architecture, and the verification evidence an independent assessor needs to sign off. We apply the same functional-safety rigor described in our ISO 26262 functional safety explainer — the automotive-grade discipline behind hazard analysis and safety case documentation — to industrial and process-control programs governed by IEC 61508 instead.
What functional safety compliance for embedded systems actually requires from an engineering partner working to industrial automation standards (IEC 61508).

SIL determination and risk graph analysis performed against IEC 61508 before a single line of safety firmware is written.

Redundant sensing, diagnostic coverage, and fail-safe state design engineered into the control system from the start.

Structured V&V evidence — FMEDA, fault injection, and diagnostic test coverage — built to satisfy an independent safety assessor.

Safety case documentation and assessor liaison support through functional safety certification for embedded products.
Explore the real Embien services that support SIL rated functional safety for industrial control systems, from platform engineering through connectivity.

Hardware and firmware architecture for controllers and PLCs engineered against industrial automation standards (IEC 61508).

Full product engineering for SIL-rated automation hardware, from schematics through in-house manufacturing.

Protocol stacks and connectivity engineering that preserve safety integrity across networked control systems.
Tell us about your control system, its target SIL, and where it stands today. An engineer will help you plan the path through industrial automation standards (IEC 61508) certification.

It requires a documented hazard and risk analysis, a SIL allocation for each safety function, and evidence — FMEDA, diagnostic coverage, V&V records — that the hardware and firmware meet that SIL. Functional safety certification for embedded products is built on that evidence chain, not a single design review.
Tell us where your industrial control system stands against IEC 61508 and SIL requirements. An engineer will follow up directly.
