Industrial automationwired into the business

We program controllers, from Siemens PLCs to ESP32 and Arduino boards, build the operator interfaces and connect everything over the network to the company's servers and applications: reports, alerts, payments, access.

We work on all five layers, not just one.
What we do

Six areas, one way of working

Each area is backed by hands-on experience with real equipment, not just a simulator.

PLC programming

Control logic for Siemens PLCs, tested in simulation before commissioning.

  • TIA Portal
  • testing with PLCSIM
  • program documentation

HMI and SCADA

Operator screens, alarms and history, linked to the other systems.

  • WinCC Unified
  • alarms and trends
  • controlled remote access

ESP32 and Arduino

Dedicated controllers for equipment that doesn't justify a PLC: payment kiosks, turnstiles, relays.

  • firmware in numbered versions
  • remote updates
  • schematics and circuit boards

Communications and IoT

Field data sent where it needs to go, without running cables to every computer.

  • MQTT
  • services on a PC next to the equipment
  • central control

Industrial networks

Industrial switches, segmentation and remote access over VPN, configured and documented.

  • Hirschmann, Moxa, Phoenix Contact switches
  • FortiGate firewall
  • VPN between sites

Monitoring and alerts

Equipment and server status tracked continuously, with a phone notification when something is out of the ordinary.

  • push notifications
  • server temperatures and fans
  • event log
The difference

Automation doesn't stop at the panel

The part usually missing is the link between the equipment and the company's software. We build that too, over the network, VPN, API and MQTT.

In the field

  • PLCs, controllers and relays
  • sensors, cash acceptors, QR readers
  • turnstiles, barriers, access readers
  • operator interfaces

In the office

  • databases and reports
  • card payments and invoicing
  • phone and e-mail alerts
  • backup and monitoring
Projects

Banknote and coin payment kiosk for turnstiles

Banknote and coin acceptor linked to the turnstile; the Arduino version is installed, the ESP32 version with monitoring is in progress.

Secure time attendance and access control

The attendance database was cleaned and repaired on a copy, then applied only after confirmation and with a backup taken first.

How we work

From schematic to commissioning

On-site analysisEquipment, signals, network and what needs to reach the company's software.
Schematic and programWiring diagram, control logic and interface, in numbered versions.
Test before installationSimulation or a test bench, so problems show up in the office, not in the installation.
Installation and measurementsWiring, commissioning and instrument checks on the real signals.
MonitoringAlerts and remote access, so work starts before the client picks up the phone.

We work with Claude here too

Claude writes and fixes the firmware and programs, proposes the connections and helps with the schematic. We do the installation, wiring, signal measurements and tests on the equipment, and their results feed the next fix.

How we work with Claude →

And for paid entrances

Turnstiles, QR tickets, card or cash payment and time attendance have their own page, with the projects where we delivered them.

Access control and payments →

In automation, nothing goes into an installation without a bench test and a person's check.

Have an installation that doesn't communicate?

Tell us what equipment you have and what you want to see in the company's software.
