About
Not greenfield mega-projects. Retrofit, migration and upgrade of plant that is already running — which is where a small, senior, multi-platform team beats a large integrator.

How we started
DNM was founded by engineers who had spent their careers inside other people's control systems — commissioning them, fixing them at three in the morning, and inheriting them with no drawings and no source code.
That is still the work. Most of what we are asked to do is not a new plant. It is a plant that already exists, that already runs, and that needs to keep running while something inside it is replaced.
Multi-brand
Five controller platforms, four SCADA systems, five drive lines. More than any comparable firm in this market names — and it matters because a plant rarely runs one brand.
Senior, reachable
The engineer who writes the code commissions it and takes the call when it stops. Nobody on site has to phone somebody else to approve a decision at 2am.
Honest scope
We say what we are not the right firm for. It costs a line item occasionally and it has never cost a client.
The team
With no logo wall and no certification history, the people are the credibility. These are the ones you would actually meet.
Founder and principal engineer
Fifteen years in controls before founding DNM, most of it on fab and pharma utility systems across Chennai and Singapore. Leads the retrofit practice and is on site for every changeover window the company runs.
15 yrs · Allen Bradley · Siemens · FactoryTalk View · WinCC
Controls software lead
Owns the programming standard and the code review that every project passes before it leaves. Background in batch process control on food and nutrition plant, and the reason recipes on DNM projects are data rather than logic.
11 yrs · Siemens · Mitsubishi · Wonderware · Citect
Panel design and workshop lead
Runs design through despatch — GA and schematics, build, wiring and factory acceptance testing. Twenty years of panels means the thermal calculation gets done rather than assumed.
20 yrs · Panel design · MCC · VFD panels · Hazardous area
Commissioning and site support
The engineer clients call when something has stopped. Covers start-up, breakdown response and the scheduled visits under annual maintenance contracts, across all five controller platforms.
9 yrs · Allen Bradley · Schneider · Omron · Drives
How a project runs
Seven steps. Each one produces something you keep, whether or not the project proceeds to the next.
A conversation with an engineer, not a form response. What the plant is, what has gone wrong or what is changing, and what your constraint actually is — usually a date or a shutdown window.
You getA same-week call and an honest view of whether we are the right firm for it
What is actually installed, rather than what the drawings say. I/O count, network topology, controller and SCADA versions, licence position, backup state, spares held, and photographs of everything.
You getAn as-found report you keep whether or not you proceed
What the system will do, agreed in writing with the people who will operate it as well as the people buying it. Disagreements found here cost a meeting. Found during commissioning they cost a shutdown.
You getAn approved FDS and a fixed scope
Panel built and wired, program written and simulated, screens developed — all off-line while your plant keeps running. Then tested on the bench against a written schedule, with I/O forced point by point.
You getA signed FAT record, and an invitation to witness it
Delivery, positioning, termination and loop checks. Every field device proved end to end from the device to the value on the screen.
You getSigned loop check sheets and an SAT record
Dry runs, then wet runs, then production, with an engineer on site until it holds. Interlocks are deliberately tripped and observed rather than assumed to work.
You getA closed-out defect list and operator handover at the panel
On-call response, scheduled visits, and periodic program backups that are proved to restore rather than merely taken.
You getA support agreement with a response time we can actually meet
