Avenxor builds PLC-based control systems for hospital operating theatres, cleanrooms, building services, and process lines. Our deployments cover air handling and pressure cascades, medical gas pipeline monitoring, lighting and door interlocks, HVAC sequencing, and full SCADA / HMI integration for operator visibility. Every program is written in IEC 61131-3 (ladder logic and structured text) with naming, comments, and modular function blocks that maintenance teams can actually read three years later — not the opaque vendor templates that lock you in. We design to NFPA 99 for healthcare facilities, HTM 03-01 for ventilation, and GMP Annex 11 for validated environments where the controller itself is a regulated component. Hardware we work with spans Siemens, Allen-Bradley, Mitsubishi, Schneider, and Omron, paired with HMI panels and SCADA stacks that fit the operator workflow. Every project ships with as-built control narratives, fully commented program source, a structured I/O list, and an operator training session — so the system runs without us, and stays auditable on day one.
Which PLC brands does Avenxor work with?
We program and integrate Siemens (S7-1200, S7-1500), Allen-Bradley (CompactLogix, ControlLogix), Mitsubishi (FX, Q), Schneider (M340, M580), and Omron (NJ, NX). Choice is driven by client standardisation, available local service support, and the regulatory regime of the deployment.
Do you build HVAC and operating room control for hospitals?
Yes. Avenxor has shipped full operating room control suites covering HVAC sequencing, positive-pressure cascades, medical gas alarm aggregation, surgical lighting interlocks, and HMI dashboards aligned to NFPA 99 and HTM 03-01 requirements.
Can your PLC programs be audited by a third party?
Yes — that is the design intent. Programs are written in IEC 61131-3 with consistent naming conventions, structured function blocks, inline comments, and an as-built control narrative document. Anyone with PLC literacy can audit the code without us in the room.
Do you handle SCADA and HMI as part of the engagement?
Yes. SCADA and HMI design (Ignition, WinCC, FactoryTalk, Mitsubishi GT) are part of the same deliverable as the PLC program, so alarm hierarchies, operator workflows, historian tagging, and access control are coherent across the stack.
How do you handle commissioning and operator training?
Commissioning is staged: factory acceptance test, then site acceptance test with the operator team, then a structured training session covering normal operation, alarm response, and safe shutdown. A training pack and quick-reference cards are left on site.
What about validation for GMP / regulated environments?
For GMP Annex 11 work we provide IQ / OQ / PQ documentation, a validation plan, traceability matrix linking user requirements to test cases, and change-control procedures so the control system is ready for audit from day one.
Have a plc systems challenge?
Let's talk.
Most engagements start with a 30-minute call. Describe the problem — we'll tell you honestly if we're the right team.
