Estimates for a small start in Australia, not guarantees.
What it is
You write and fix the control software (PLCs, HMI screens, simple robot programs) that runs machines and production lines. Most work is done at your desk, with some days on site to commission and fine-tune.
Your first three steps
- Pick one or two PLC brands common in your area and get the software and a small test kit
- Tell former employers, local integrators and machine builders you are available for contract work
- Set up an ABN, quote template and insurance, then take on a small upgrade or fault-finding job
Who pays
Local manufacturers, food and packaging plants, larger integrators who need extra hands, and machine builders.
How it makes money
Day or hourly rates for programming and commissioning, or fixed quotes for small upgrades. Support retainers can add steady income.
Skills that help
- PLC and control programming
- Reading electrical and process drawings
- Clear communication with plant staff
- Careful testing and documentation
Watch out for
- Public liability and professional indemnity insurance, as a software fault can stop a production line
- Electrical work such as wiring usually needs a licensed electrician, so check your state's licensing rules and partner where needed
- Machine safety standards (such as the AS 4024 series) and site safety inductions
- Software licence costs and customer ownership of the code, so agree terms in writing
- Check whether your council requires approval for a home-based business
