Practical notes on PLC programming, SCADA/HMI design and control panels from the engineering team at AVACON Technologies, Islamabad.

A PLC program is the brain of a production line, pump station or HVAC system. When it is written well, operators hardly notice it; when it is rushed, every fault becomes a long night of troubleshooting. Since 2011, AVACON has programmed Siemens, Allen-Bradley, Omron and ABB controllers for manufacturing, food, pharmaceutical and hydropower clients across Pakistan.
A good PLC project starts with a clear functional description: what each motor, valve and sensor does, in which sequence, and what must happen on every alarm. From there we build a tag list, structure the code into reusable blocks, and simulate it before anything is wired. On site, we commission step by step and hand over commented code and documentation, so your maintenance team can support the system after we leave.
Whether you need a new control system, an upgrade of a legacy PLC or help finding a fault in an existing program, contact us to discuss your project, or see our automation services.

Real-time visibility into a production line, water system or power plant starts with a well-designed SCADA and HMI. The best systems are not the ones with the most graphics; they are the ones that show the right information at the right moment.
Our approach starts with how your operators work. We keep overview screens simple, use consistent colors for running, stopped and faulted equipment, and make alarms specific enough to act on. Behind the screens, we design a SCADA architecture that logs the data you need for reports and grows with your plant. AVACON has delivered SCADA and HMI systems for pharmaceutical and vaccine production, power plants, food processing and HVAC building management.
Want your team to build and maintain HMIs themselves? Our HMI and SCADA training covers screen design, alarms, trends and PLC communication.
