Plant-WideSupervisory Control
SCADA and HMI systems that put every process variable, alarm and trend on one screen — designed, configured and commissioned by our own engineers.
Trusted on site by
Industrial Automation
Control systems designed, built and commissioned in-house
From a single PLC retrofit to a plant-wide control system — we engineer the design, build the panels, write the code and stay on site through commissioning. On new plant, and on equipment that has been running for decades.
Platforms we work across: Siemens · Allen-Bradley · Delta · Schneider · Phoenix Contact · CG
System Integration
PLC, drives, instrumentation, safety and IIoT tied into one system that one team can support — including legacy equipment.
End to end solution, under one roof
Drawings, panel build, code and commissioning all come from the same team — so there is no gap between who designed it, who wired it and who answers the phone when it stops. One contract, one point of responsibility.
- 01
Design & Engineering
Control philosophy, I/O schedules, single-line and panel drawings agreed before anything is cut.
- 02
Panel Manufacture
Built, wired and routine-tested in-house, so the build and the logic come from the same team.
- 03
Factory Acceptance Test
Logic proven against simulated I/O with you present, before a panel leaves the works.
- 04
Installation & Commissioning
Loop checks, live tuning and operator handover on site, carried out by our own engineers.
- 05
Support & AMC
Breakdown response, spares holding and planned maintenance under contract once you are running.
Retrofit & Migration
Ageing control systems, brought forward without losing a shift
An obsolete PLC or an unsupported drive should not become an unplanned shutdown. We reverse-engineer what is on the floor, map every loop to the new architecture, and stage the changeover around your production window.
- Reverse-engineering of undocumented logic
- Loop-by-loop verification against the old system
- Changeover planned around your shutdown window
- Operators trained before the old panel goes
Industries we work in
SENTIENT — our IIoT platform
One platform, from a single gateway to a plant-wide cluster
SENTIENT is our own industrial IoT and SCADA platform — device management, dashboards, alarms and a rule engine, together with the local process control, PLC connectivity, reporting and recipe handling that day-to-day plant work depends on.
Built to run a working plant
Dashboards are where it starts. SENTIENT also carries the local control, recipes, reporting and analytics a plant leans on once it is in daily production.
Written in Rust
Small enough for a gateway, built to cluster
The backend is a Rust application, so it runs in a fraction of the memory a JVM platform needs. That is what lets the same build sit on a low-power box beside the panel and also scale out across a cluster — no separate cut-down edge edition, no second system to learn.
Gateway on the wall
Low-power hardware next to the panel, holding its own data and screens when the network drops.
One server on-premise
A plant-wide historian and SCADA on your own hardware, inside your own network.
High-availability cluster
Multiple sites into one system, cloud or on-premise, with redundancy where downtime costs real money.

What a design package contains
Every drawing and calculation a contractor, an inspector and your own maintenance team will ask for — well beyond a single-line diagram and a bill of materials.
Testing & Analysis
Diagnostics that go well past a routine check
Transformers, GIS and AIS switchgear, breakers, changeover switches and relays — routine and special testing, condition monitoring, thermography, partial discharge and power system studies, at every voltage level.
Equipment we test
Instruments we work with
Relays can be integrated into your existing SCADA, or a new one.
Where we work
Mechanical Systems
The iron is fine. It is the controls that aged
A mechanically sound machine does not need replacing because its control is obsolete. We fit new controllers, drives, motors and operator panels to machine tools and cranes you already own, build special purpose machines where nothing off the shelf fits, and take on crane electrics from hoist motion to radio remote control.
Cranes and material handling
The same argument applies to a crane. The structure outlives its controls by decades, so we renew the electrics and leave the steel in service.
EOT cranes
Electric overhead travelling cranes — long travel, cross travel and hoist motions re-controlled, with VFDs replacing contactor-and-resistor stepping.
Double girder cranes
Heavier duty and longer spans, including anti-sway, load monitoring and synchronised motion where two hoists work together.
Single girder & monorail
Underslung and monorail hoists for bay and workshop handling, with festoon or conductor-bar power supply.
Hoists and winches
Wire rope and chain hoists, brake and limit switch replacement, and overload protection proven to trip at its setting.
Radio remote control
Pendant replaced with radio remote so the operator can stand where they can see the load, with interlocked handover between stations.
Crane safety systems
Limit switches, anti-collision, load cells and zone protection — wired into the drives rather than bolted on as an afterthought.
What we replace
- CNC controller
- Servo drives and motors
- Encoders and position feedback
- Spindle drive (VFD)
- Operator panel and HMI
- Electrical panel and wiring loom
- Limit switches and machine I/O
What stays exactly as it is
- Bed, column and castings
- Spindle and bearings
- Ball screws and guideways
- Tool changer and turret
- Hydraulics and coolant system
- The machine’s original geometry
Spares that no longer exist
When a control is obsolete, one failed board can idle the machine for weeks. A current platform keeps spares on a shelf and available next day.
Accuracy you already paid for
Castings, ball screws and guideways have decades of life left. Scrapping a mechanically sound machine throws away the part that took years to settle.
A control your programmers can use
Modern programming, networking and on-screen diagnostics, so the machine joins the rest of the shop on the same network.
Machines we retrofit
Special Purpose Machines
When nothing off the shelf does the job
Some operations have no standard machine. We design and build one around the job — mechanics, drives, control and safety as a single package, sized to your cycle time and your floor space.
- Built around one operation and its cycle time
- Mechanical, electrical and control from one team
- PLC, HMI and safety designed in from the start
- Documented and supported like any other machine
How a retrofit runs
A machine out of production is costing money, so the survey and the panel build happen before anything is stripped.
- 01
Survey & feasibility
Geometry, backlash, spindle and screw condition checked first — if the iron is not worth retrofitting we will say so.
- 02
Control design
Controller, drives and motors sized to the machine, with schematics and an I/O list before anything is ordered.
- 03
Panel build
The control panel is manufactured and wired in our own works, then tested before it reaches your floor.
- 04
Installation
Old controls stripped out, new gear fitted, axes aligned, tuned and backlash compensated.
- 05
Commissioning & training
Accuracy verified against test cuts, then your operators and maintenance team trained on the new control.

Panel manufacturing unit
Our own works building LT switchgear, distribution boards, control & relay panels, PLC panels and starter panels.
Site team
Erection, testing and commissioning carried out by our own engineers — including remote hydro sites in Ladakh and Arunachal.
