30+ YEARS OF INDUSTRIAL AUTOMATION EXPERTISE
Large factories optimize and eliminate downtime. Growing companies modernize and scale smart. With PICSYS
What we do
Suboptimal cycle times. Inefficient legacy controls. Production bottlenecks. PICSYS solves these problems.
The company was founded in 2005 by Dragan Nikolic, an electrical engineer with over 30 years of hands on experience inside massive facilities like HIP Azotara, Sever ERA, and Mikro Kontrol, as well as smaller production lines. Most engineers specialize in one or the other. We do both.
Whether you need faster cycle times or a legacy PLC rescued, PICSYS delivers.

Our Services
PLC Programming & Control System Design
Custom PLC programming for Siemens, Omron, ABB, and Schneider Electric. We write structured, documented, and safety-compliant code (IEC 61131-3) that your team can actually troubleshoot.
SCADA & HMI Development
From operator panels to full SCADA visualization (WinCC, Ignition, FactoryTalk, CODESYS). We build intuitive interfaces that give your operators real-time control and clear alarm management.
Production Line Modernization
Legacy systems failing? Obsolete PLCs causing downtime risk? We migrate your production line to modern, supported platforms with minimal interruption to your operations.
Industrial Emergency Response
Production stopped? Every hour costs tens of thousands. We prioritize emergency calls. Remote diagnostics available immediately. On-site support dispatched within hours for Serbian clients.
Variable Frequency Drives & Motion Control
We design and commission VFD systems for pumps, conveyors, fans, and precision motion control. The result is energy savings, precise positioning, faster cycle times, and less mechanical wear on your equipment.
Sensor & Instrumentation Integration
We bring specialist level expertise to sensors from Balluff, Datalogic, Festo, and other major brands. We select the right field devices for your application, integrate them properly, and calibrate them for reliable readings, fewer nuisance alarms, and optimized overall performance.
Why PICSYS
Quality, Safety & Professional Standards
Quality means documented, reusable code and full FAT plus SAT testing. Safety means every control system meets EN ISO 13849, IEC 61508, and SIL standards before you run a single production cycle.
Quality Practices
- Structured, documented, and reusable PLC code per IEC 61131-3
- Factory Acceptance Test (FAT) plus Site Acceptance Test (SAT) before handover
- Full documentation: wiring diagrams, I/O lists, commented code, operator manuals PLC code per IEC 61131-3
- Brand agnostic: we recommend the best hardware for your job, not our preferred brandPLC code per IEC 61131-3
Safety Standards
- EN ISO 13849 for safety related parts of control systems
- IEC 61508 for functional safety of electrical and electronic systems
- SIL (Safety Integrity Level) for safety PLC programming and risk assessment
About PICSYS
PICSYS is a specialized industrial automation engineering firm based in Subotica, Serbia. We serve both local and international industrial clients who need expert PLC programming, SCADA/HMI development, control system design, and production line modernization.
Unlike large integrators with high overhead, we offer direct access to a senior engineer with three decades of experience. When you work with PICSYS, you work directly with the person who designs, programs, and commissions your system.
CEO & Managing Director of PICSYS d.o.o.
Driving Industrial Excellence Since 2005.
Dragan Nikolić
I founded PICSYS in 2005 and have been running this firm to drive industrial excellence based on my 30 years of experience as an electrical engineer working inside industrial facilities of every size.
That experience taught me one thing: large system thinking and small budget discipline rarely come from the same person. At PICSYS, this is our core motive: to assess your factory’s needs for optimal workflows.
I personally program every PLC and SCADA system we deliver, integrate all sensors and drives alongside our partnering teams across different industries, and handle safety compliance. When you call PICSYS, you reach me. An engineer who owns the work from start to finish.
Over the years, PICSYS has collaborated with companies across multiple industries including
In addition, our team has successfully completed automation and optimization projects across various sectors, such as
- Animal Feed & Agriculture: collaborating with leading feed manufacturers and agricultural producers.
- Machinery & Motion Control: providing VFD tuning and control system optimization for equipment specialists.
- Renovation & Infrastructure: delivering control system solutions for construction and infrastructure firms.
- Renewable Energy: working with producers in the pellet and alternative energy sector.g warehousing, logistics operations, and public institutions.
- Logistics & Public Sector: supporting warehousing, logistics operations, and public institutions.

Frequently Asked Questions
Automotive manufacturing, food and beverage production, pharmaceuticals, oil and gas, water/wastewater treatment, and general heavy manufacturing.
Yes. Many integrators only work with new equipment. We specialize in legacy system modernization and can also maintain, repair, and source parts for older PLCs when replacement is not immediately feasible.
Siemens, Omron, ABB, Schneider Electric, Balluff, Datalogic, Festo, and more. We are brand-agnostic, and we recommend the best solution for your specific application, not the brand we prefer.
Absolutely. Emergency response is one of our core services. Call our direct number for immediate remote diagnostics. For clients in Serbia, we can often be on-site within hours.
We are based in Subotica, Serbia but serve international clients. Remote support, documentation, and commissioning travel are all available. Contact us to discuss your location.
Every project includes: commented PLC code, I/O lists, wiring diagrams, HMI/SCADA screen layouts, operator instructions, and a commissioning report (FAT + SAT).
Projects are typically quoted fixed-price after an initial assessment. Emergency response is billed at an hourly rate. No hidden fees.
We analyze your existing PLC logic, sensor response times, and mechanical sequences. Then we optimize code structure, reduce unnecessary scan cycles, and tune VFDs. The result is faster cycle times and smoother production flow without changing any hardware.
