HIMA Safety PLC Engineers in France – Functional Safety Automation Experts
Are you looking for a certified HIMA automation engineer to manage your industrial safety PLC systems? As a trusted service provider in France, we are renowned for our expertise in SILworX programming and our ability to deliver high-quality safety automation solutions that keep your systems operating securely and reliably.
Whether you need support with design, installation, or maintenance, we have the skills and experience to do the job right — compliant with the highest functional safety standards (SIL 2 / SIL 3).
Programming, testing and commissioning of HIMA systems
Intervening on a safety PLC is not simply a matter of modifying a program. It requires understanding the cause-and-effect matrix, permissives, safe states, interfaces with the DCS, input/output wiring, and validation procedures applied on site.
INOMATEX can intervene in a targeted phase or reinforce your team throughout the entire project: analysis of the existing system, development or modification of SILworX, test preparation, FAT, SAT, loop checks, commissioning, diagnostics, and delivery of documented backups. The scope of responsibility, the functions involved, and the acceptance criteria are defined before any modification of a safety function. To place this service within a broader context, consult our engineering, PLC programming, and commissioning services .
Intervention on SILworX, HIMax, HIMatrix and HIQuad X
SILworX is the HIMA environment used to program, configure and diagnose safety controllers in the HIMax, HIMatrix and HIQuad X ranges. These platforms are used in functional safety applications up to SIL 3, depending on the configuration, certificates and applicable lifecycle.
The exact scope of a mission depends, however, on the hardware generation, software version, available licenses, backup quality, and applicable modification rules on site. Before confirming an intervention, INOMATEX verifies the CPU and module specifications, project version, redundancy architecture, communications, security documentation, and testing capabilities.
For older installations, feasibility is validated on a case-by-case basis to avoid any promises incompatible with available tools, licenses, or hardware. Discover HIMA security platforms.
A modification method adapted to security functions
Modifying a HIMA system must be prepared and verified in a structured manner. INOMATEX works from the documents applicable to the project: functional specification, cause-and-effect matrix, input/output list, electrical diagrams, network architecture, FAT/SAT procedures, and version control rules.
This intervention does not replace the responsibility of the designer of the safety-instrumented function, nor the validations required by the operator. Our role is to translate the approved requirements into testable technical modifications, to perform the agreed-upon tests, and to provide traceability that can be used by the client's teams. When the project falls under IEC 61508 or IEC 61511 standards, the activities are carried out within the documentation and responsibilities defined by the operator and the parties responsible for functional safety.

HIMA Applications: ESD, Fire & Gas, Burner Management System and Critical Processes
HIMA safety PLCs are used when an installation needs to reach or maintain a safe state after a hazardous condition is detected. INOMATEX primarily operates in process and infrastructure environments where safety sequences are heavily interfaced with control systems, DCS, instrumentation, and field equipment.
The tasks may involve ESD emergency shutdown systems, Fire & Gas interfaces, Burner Management Systems (BMS), equipment protection, start-up permits, generator or machine shutdowns, and data exchange between SIS and DCS. The exact functions remain defined by the safety studies and approved project documents.

A HIMA experience directly linked to field commissioning
INOMATEX has experience with HIMA SILworX systems in LNG, Oil & Gas and offshore projects. On these installations, testing is not limited to the controller: it also involves sensors, valves, emergency stops, DCS exchanges, PMS or CPMS systems and field equipment.
This comprehensive approach facilitates the analysis of faults that appear during FAT, SAT, or startup: unmet logic condition, inverted signal, wiring fault, inconsistent state, unavailable communication, or poorly coordinated sequence.

How to obtain a HIMA service with INOMATEX?
INOMATEX adapts its approach to the project's maturity level and the duration of the need. A mission can be carried out as a consultancy to define a problem, as a subcontractor to handle a specific work package, or as on-site technical assistance to integrate a HIMA automation specialist into the client's team.
To quickly assess your request, please provide the HIMA platform, the SILworX version, the main hardware references, the application type, the intervention location, the desired dates, and any available documentation. This information will allow us to verify tool compatibility, the required access level, and the resources needed for testing.
