Services

From the sensor to the dashboard.

Six complementary areas of expertise, delivered by the same team. For each: what your teams go through, what we deliver, with which technologies and how fast.

01 / 06

PLC automation & control

What your teams go through

Manual sequences, stops caused by a single sensor, a program nobody dares to touch.

What we deliver

Functional analysis, structured and commented programs, cabinets, FAT on a simulator, commissioning, training.

Technologies: TIA Portal · S7-1200/1500 · Unity Pro · Studio 5000 · Profinet · Profibus
Typical lead time: 6 to 16 weeks

Do you work on existing PLCs?

Yes. We follow your naming standards and installed hardware, and we document what we find.

Who owns the programs?

You do. Commented sources are handed over at acceptance, with no lock-in clause.

02 / 06

SCADA & HMI

What your teams go through

Screens full of colour, ignored alarms, data lost at every restart.

What we deliver

ISA-101 mimics, rationalised ISA-18.2 alarm database, history, reports, secure remote access.

Technologies: WinCC Unified · Ignition · AVEVA · EcoStruxure · OPC UA · SQL
Typical lead time: 4 to 12 weeks

Why grey screens?

Reserving colour for abnormal situations lets you see what matters at a glance: that is the ISA-101 principle.

Can we monitor remotely?

Yes, read-only by default, over VPN with named accounts. Any command requires strong authentication.

03 / 06

IIoT & data

What your teams go through

OEE worked out by hand on Mondays, figures disputed in meetings.

What we deliver

Edge gateways, OPC UA and MQTT collection, automatic OEE, web dashboards, exports.

Technologies: OPC UA · MQTT · Modbus TCP · Node-RED · InfluxDB · Grafana
Typical lead time: 3 to 8 weeks

Do we need to replace our machines?

Rarely: a gateway reads your existing PLCs without changing their program.

Where is our data?

On your site or with the host of your choice. It is never resold.

Typical architecture

Sensors and actuators

Role: measure and act on the process. Hardware: 4–20 mA sensors, valves, drives. Protocols: hard-wired signals, IO-Link. Watch point: calibration and tagging of every point.

PLCs

Role: run sequences and protect. Hardware: S7-1500, Modicon, ControlLogix. Protocols: Profinet, Profibus, EtherNet/IP. Watch point: program backups and access control.

Edge gateway

Role: read PLCs without changing them and keep 30 days of data. Hardware: SAE-EDGE2, DIN rail. Protocols: Modbus, S7, OPC UA client. Watch point: firewall, named accounts, signed updates.

OT network (OPC UA, MQTT)

Role: carry data between the plant and the outside world. Hardware: managed switches, 4G routers. Protocols: OPC UA, MQTT over TLS. Watch point: zones and conduits following IEC 62443 principles.

Supervision and history

Role: show the plant and keep its history. Hardware: redundant or virtualised server. Protocols: OPC UA, SQL. Watch point: read-only by default, strong authentication for any command.

Dashboards

Role: give the plant manager the figures, every morning. Hardware: shop-floor screen, browser. Protocols: HTTPS. Watch point: a single written, shared definition of each indicator.

04 / 06

Industrial electrical

What your teams go through

Cabinets running hot, unexplained trips, missing drawings.

What we deliver

Main boards, control cabinets, drives, transfer switches, thermography, compliance work.

Technologies: IEC 61439 · NF C 15-100 · NF C 18-510 · variateurs · inverseurs
Typical lead time: 4 to 12 weeks

Do you work live?

No. Lock-out is systematic; only measurements are taken, by authorised staff.

Do you offer thermography?

Yes, with a report that ranks hot spots by priority.

05 / 06

Energy: hybrid solar & efficiency

What your teams go through

Diesel, outages and rising bills weigh on every month.

What we deliver

Energy audit, solar-diesel-battery hybrid plants, drives, consumption monitoring.

Technologies: Solaire PV · LiFePO4 · groupes électrogènes · Modbus TCP · compteurs
Typical lead time: 8 to 24 weeks

How much diesel can we save?

Often 25 to 45% with a hybrid plant, depending on sunshine and load, after an audit.

And at night?

Batteries and generator are managed automatically: nobody has to step in.

Calculator: what does a variable speed drive save?

Affinity laws: on a pump or a fan, cutting speed by 20% roughly halves the power.

Estimated saving per year

9,690,000 FCFA

Energy before: 216,000 kWh
Energy after: 114,014 kWh
Energy saved: 101,986 kWh
Investment: 8,100,000 FCFA
Payback: 10.0 months

Indicative estimate, valid for centrifugal pumps and fans without high static head. An audit measures your actual case.

06 / 06

Maintenance, retrofit & on-call

What your teams go through

Obsolete PLCs with no spares, night-time breakdowns, technicians alone facing the unknown.

What we deliver

S5 / S7-300 to S7-1500 migration without long shutdowns, preventive work, 24/7 on-call, critical spares, training.

Technologies: S5 → S7-1500 · rétrofit · préventif · astreinte 24/7 · pièces critiques
Typical lead time: annual contract

What is the response time after a breakdown?

4 h in Douala, 8 h in the Littoral region and around Garoua, 24 h elsewhere in Cameroon: written into the Continuity contract.

Do you keep spare parts?

Yes, the stock is agreed with you in the Performance contract.
