TOPIC: SMART AUTOMATION: MAKING PLANTS SAFER AND MORE EFFICIENT
In modern industrial plants, automation is evaluated not only on performance, but also on its ability to ensure reliability, safety, and long-term sustainability.
Marsina Engineering presents its PLC-based automation approach, designed to deliver precision, operational continuity, and flexibility across the plant lifecycle. Built on the Siemens S7-1500 PLC family, the system features a modular and scalable architecture suitable for plants of varying size and complexity. Drawing from field experience, our philosophy challenges the assumption that more redundancy automatically increases reliability. Most critical plant faults are not caused by automation failures and cannot be solved by excessive redundancy; our designs pursue a balanced trade-off between resilience, simplicity, and cost-effectiveness.
During the presentation, we will explore the system’s layered software architecture, including hardware interfacing, equipment abstraction, and process/alarm management. We will discuss hardware selection strategies, integration of PLC + HMI or PLC + SCADA solutions, and multi-level safety features, including walk-away protection. Practical examples will illustrate how these elements work together to ensure consistent system behavior, clear operator interaction, and efficient plant management.
This approach demonstrates how a modern PLC-based automation system can be not only efficient and safe, but also insightful to study, analyze, and continuously optimize.
