How can we help?

 

Industrial Automation & Control Systems Darwin

Automation & controls · Darwin industrial corridor

PLC, SCADA, HMI, control panels and instrumentation for plants, pump stations, workshops and remote sites, built so your own people can keep it running after we leave.

From one machine to a multi-line site. And when a stock controller doesn’t fit, or the original is no longer made, we design and build the controller ourselves.

Workshop

Winnellie, Darwin

Free first consultation and a written scope before any work

PLC, SCADA, panels, instruments, networks. And the odd custom controller.

PLC programming

New logic and changes to existing logic on Allen-Bradley, Siemens, Schneider, Omron, Mitsubishi and Beckhoff, including brownfield sites where nobody kept the documentation. Version-controlled and handed over readable.

SCADA and HMI

Ignition, AVEVA and FactoryTalk, or open-source stacks where they fit. Operator screens designed with the operators, alarms that mean something, trending and history.

Control panels

Designed, built, wired, labelled, tested and documented in the workshop. Motor control, distribution and process cabinets, IP-rated for humidity, dust and salt air. Legacy panels refurbished with serviceability designed in.

Instrumentation

Flow, level, pressure, temperature and vibration instruments selected, installed and loop-checked. 4-20 mA, HART, Modbus, Profinet, EtherNet/IP, OPC UA and MQTT. LoRa and wireless where cable can’t go.

Industrial networks and OT

Segmented, monitored networks with a proper boundary to the office IT, and vendor remote access through auditable paths rather than open ports.

Controller and drive repair

PLCs, drives and control boards repaired at the component level, including lightning and surge damage. Spares strategy and obsolescence planning for the gear that runs the site.

Custom controllers

When the stock PLC has the wrong I/O, the wrong form factor or no local support: relay panels, multi-channel I/O boards, motor and actuator drives, data loggers and PLC-style controllers designed and built here. See product design.

Reverse engineering

Undocumented logic and dead controllers on machines the business depends on. We work out how they work, document them, and repair or replace them.

Ongoing support

Monitoring and support plans for live operational systems with real response expectations. See support plans.

Scope. Build. Hand over readable.

  1. Free consultation

    What the site does, what’s failing or missing, and who has to run it afterwards. Phone, workshop or a site visit.

  2. Written scope and quote

    Fixed scope where the job allows, hourly where it’s fault-finding. Parts lead times to Darwin built in.

  3. Commission and document

    Tested with your operators, then handed over with drawings, logic, tag lists and a plain-English guide so the next person can pick it up.

What it costs

Repair-first. We’d rather refit and document a working system than rip it out for billable hours.

Jobs to give you the idea.

Steel-mill pipe bender revived

Dead controller, manufacturer gone. We built new relays, sensors and a controller with web management, plus secure remote access over 4G with no fixed IP. Files move on and off the machine from anywhere.

Offshore aquaculture controllers

Networked relay controllers in IP67 cases, Modbus over Ethernet with 4G fallback, switching feed equipment at sea.

Storm-damaged PLC I/O

Burnt inputs and outputs on a shed controller after a lightning strike, repaired at the board level and the site protected for the next wet season.

Common questions

Can you work on a system somebody else installed?

Yes. Most of our automation work is on existing sites. We document as we go, so it’s in better shape when we leave than when we arrived.

Our controller is obsolete and the machine still works. What are the options?

Repair it, source a compatible unit, or design a replacement that fits the same panel and wiring. We’ll tell you which makes sense for the age and value of the machine.

Do you cover Katherine and remote sites?

Yes. Scheduled trips to Katherine and beyond, remote access for support, and gear couriered to the workshop for repair.

Which PLC brands do you program?

Allen-Bradley, Siemens, Schneider, Omron, Mitsubishi, Beckhoff and open-spec controllers. If it’s something else, ask.

Can the site be monitored remotely without exposing it to the internet?

Yes. Segmentation plus a logged VPN or jump host, so we and your vendors get in without leaving the site an open door.

Darwin industrial corridor, Palmerston, and out to Katherine.

Winnellie, Berrimah, East Arm and Yarrawonga are minutes away. Palmerston, Howard Springs, Humpty Doo and the rural area are regular work, with scheduled coverage to Katherine and remote sites.

Before we visit

Photos of the panel, the controller labels and any drawings you have save a first trip. Error codes and when it started help too.

The first consultation is free. Site visits are quoted before we come out.
