Certifications & standards
What we work to, and what we hold
Two different things, listed separately. Standards are a way of working. Certificates are a possession, and we would rather show an honest gap than a badge you cannot verify.
Standards
How the work is structured
No certificate is implied by any of these, and none is needed to state them.
PLC programming languages
Ladder, function block, structured text and sequential function chart, chosen per problem rather than per habit. Named in DNM's own capability brief as the programming standard the team works to.
Industrial automation and control system security
Network segmentation, controlled remote access, account handling and patch discipline on OT networks. DNM works to its principles; this is a design posture, not a certification.
Functional safety, process sector
Where a safety instrumented function is in scope, it is designed to IEC 61511 with a stated integrity level, or referred to a functional safety specialist. It is never implemented inside a basic process control system and described as done.
Batch control models
Recipe, unit and phase separation on batch plant, so a new product is a data change rather than a code change.
Certifications
Formal certification status
Listed with issuing body, number and dates once confirmed — in text, so a procurement team can check them rather than squint at a scan.
- Not yet confirmed
ISO 9001 — Quality management
Accredited certification body
The baseline expectation in this category. Both MKS and Macro Integration hold it.
- Not yet confirmed
ISO 45001 — Occupational health and safety
Accredited certification body
Frequently a prerequisite for site access at semiconductor and pharma clients.
- Not yet confirmed
Electrical contractor licence
Tamil Nadu Electrical Licensing Board
Licence class and number, plus the named supervisor it is held against.
- Not yet confirmed
Controller vendor partner status
Siemens / Rockwell Automation / Schneider Electric
Any partner, system integrator or solution provider status held with the controller vendors, at whatever tier.
Why this page says what it says
Nothing above is claimed as held, because none of it has been confirmed. Certification claims on an industrial site get verified by procurement teams, and a badge that does not check out costs more than the absence of one. This page updates the moment the certificates are in hand.
