One live view of the whole plant.

PLCs run the machines; SCADA shows operators what is happening and lets them act; the historian remembers it all. We design, program and connect the three so the floor runs steadily and its data is ready for everything that follows.

PLC, SCADA & historians

What It Is

A programmable logic controller reads sensors and drives motors, valves and actuators in a fixed scan cycle. SCADA (supervisory control and data acquisition) gathers data from many controllers, shows it on clear screens, raises alarms and keeps operator actions on record.

We work across brands, write structured and documented PLC code, and build SCADA screens to modern high-performance HMI practice - grey by default, colour only for what needs attention - with a historian underneath for trends and reports.

How It Works

The system from the sensor to the people who act on it. Every project is sized to the site, but the layers stay the same.

  1. Field

    Sensors & actuators

    Transmitters, switches, drives and valves wired to I/O or on a fieldbus.

  2. Control

    PLC / PAC

    IEC 61131-3 logic for sequences, interlocks, PID loops and batch phases.

  3. Connect

    Industrial network

    PROFINET, EtherNet/IP or Modbus at the machine; OPC UA or MQTT up to SCADA.

  4. Supervise

    SCADA & HMI

    Overview, process and detail screens, alarms, trends and operator logs, on the web or on panels.

  5. Store

    Historian & reports

    Time-series storage feeding shift reports, OEE and analytics.
