I have worked on several projects in my working life. Especially in the area of industrial Automation ,I have worked on the Wastewater Treatment Plant and Water Treatment Plant Automation Project. I wrote the system software with the SIEMENS TIA Portal program and the Simatic Manager program according to the automation scenario and then I worked with the SIEMENS WinCC SCADA program to monitor and control the system. I used the SIEMENS PH & INFORMATION SERVER program to report the units on a monthly, monthly and yearly basis and prepared templates for the reports. I did (PTP) point to point tests and automation tests when the units were switched on. I drew the Electricity Projects with the E plan P8 V2.6 program. In the field of process automation, I used the DELTA PLC program and the ABB PLC program to control each piece of equipment in the factory. In Energy Automation, I also worked in HES projects where I made the generators PLC and SCADA system. Ventilation systems of plants and enterprises were made according to the temperature of the environment, according to the working information of the machines and according to other factors. Ventilation system entered the circuit and worked in a certain place. I usually used ABB AC500 PLC program and ABB & SIEMENS drivers when doing these systems. I install &Comission Chocolate Machines,lines.And test all equipment then commission about process follow. I used Honeywell DCS C200 in iron steel industry and I comissioned this systems about part by part units In the field of electricity, I work actively in the fields of electric panel works, electricity projects and field applications of small enterprises in general. I used OMRON PLC some factory application with given scenario I wrote plc to control each equipment and depend on sensor etc.. I set up on the field instruments, configuration upper and lower limit values during setup, setup analogue 4.20 mA, 0-10 V. I made work such as parameter setting of ABB & SIEMENS drivers and softstarters. In Machine Automation ,I have done projects like machine process Automation and writing software depositor and other part of machines and there I used AB PLC -RS Logix 5000 and Factory talk.

A PLC programmer is an industrial automation specialist who designs, codes, and commissions programmable logic controller software that drives machinery, production lines, and process control systems. Hiring a freelance PLC programmer gives manufacturers, integrators, and OEMs direct access to control engineering talent without the overhead of a permanent automation hire.
A PLC programmer translates mechanical and process requirements into reliable control logic. They write ladder logic, function block diagrams, structured text, and sequential function charts that govern motors, sensors, valves, conveyors, robots, and safety systems. Their work keeps factories running, batches consistent, and operators safe.
Beyond writing code, a PLC programmer commissions hardware, configures I/O, integrates HMIs and SCADA systems, tunes PID loops, and documents control narratives for handover. They diagnose faults on existing lines, retrofit legacy controls, and migrate old programs to current platforms.
The PLC ecosystem is brand-specific, so confirm the controller family before hiring. Experienced PLC engineers typically work across several of these platforms:
PLC programming is in demand wherever machines run unattended or processes need precise control. Common sectors include:
Strong candidates combine hands-on commissioning experience with disciplined coding habits. Look for engineers who can read electrical drawings, work safely on live equipment, and write structured, well-commented code that another engineer can maintain.
Sample interview questions to copy and use:
Freelancer.com gives you access to a global pool of automation engineers spanning every major controller brand, HMI platform, and industry vertical. Whether you need a quick fault diagnosis on a Siemens S7-1500, a full TIA Portal program for a new machine, or a Rockwell migration, you can post a project on Freelancer.com and receive bids from qualified specialists within hours.
Profiles on Freelancer.com show verified credentials, completed project counts, client reviews, and skill tests, so you can shortlist confidently. Milestone Payments protect both sides, releasing funds only when agreed deliverables — code modules, FAT results, commissioning sign-off — are met. The platform's scale means you can find freelancers on Freelancer.com who match your time zone for live commissioning support, or who specialize in the exact niche your project demands.
Ready to get your line running or your machine commissioned?
Hiring a PLC programmer works best when your brief gives engineers enough technical context to bid accurately. The clearer your specifications on hardware, scope, and deliverables, the more precise the proposals you receive. The process below walks you through posting, reviewing, and awarding your automation project.
The project brief is the single biggest factor in bid quality. PLC work is highly platform-specific, so a brief that names the controller, HMI, network, and deliverables filters out generic responses and attracts engineers with directly relevant experience. Head to the
Bids are short proposals, not just price quotes. A strong PLC programmer will reference your specific platform, ask targeted questions about I/O or sequence logic, and outline a realistic approach for development, testing, and commissioning. Use the bid quality to gauge how well each candidate has read your brief.
The award decision combines proposal quality with profile evidence. For PLC work, look for consistent delivery across multiple controller brands and industries, not just one impressive project. Reviews from past clients often reveal how the freelancer handles late-stage commissioning issues — the part of automation projects where things actually go wrong.
Small modifications or fault-finding tasks can be completed in a few days, while a full machine program with HMI and commissioning typically runs several weeks. Process control projects with validation requirements can extend over months. Timelines depend on I/O count, number of recipes or modes, and whether site commissioning is included.
Yes. Many PLC programmers handle development, simulation, code reviews, HMI design, and remote commissioning over VPN entirely off-site. On-site work is usually reserved for initial wiring checks, FAT, and final SAT, though even these are increasingly supported remotely with cameras and remote-access gateways.
A PLC programmer writes the real-time control logic that runs on the controller and interacts directly with field devices. A SCADA developer builds the supervisory software layer for operators, dashboards, historians, and reporting. Many freelancers cover both, but complex projects often benefit from specialists at each layer.
Most modern platforms offer emulators — Studio 5000 Emulate, PLCSIM Advanced, Codesys simulation — that let a freelancer develop and test logic without physical hardware. You will still need real controllers and I/O for final commissioning, but a large portion of the work can be completed and verified in simulation.
For defined scopes — a single machine, a retrofit, a code review, or troubleshooting — a freelance PLC programmer is usually faster and more cost-effective. Multi-disciplinary projects involving electrical design, mechanical work, and full plant integration may benefit from an integrator, though many freelancers on Freelancer.com can assemble small teams to cover broader scopes.
