Overview
CODESYS
CODESYS provides you with a complete development environment for industrial automation. Instead of being locked into specific hardware, you can program controllers from different manufacturers using a single, standardized tool. You can develop applications using all five IEC 61131-3 programming languages, allowing you to choose the best method for your specific logic needs, whether it is ladder logic or structured text.
The platform handles everything from basic PLC programming to complex motion control and safety functions. You can also design integrated web-based visualizations to monitor your machines from any device. It is widely used by machine builders, system integrators, and hardware manufacturers who need a flexible, professional-grade environment to manage modern industrial internet of things (IIoT) requirements.
Siemens Navigator
Siemens Navigator gives you a centralized command center to manage your entire building portfolio's efficiency. You can connect various data sources—from smart meters to HVAC systems—to gain a transparent view of your energy consumption and carbon footprint. The platform helps you identify hidden waste, verify utility bills, and ensure your facilities meet strict environmental regulations without manual data entry.
You can transform raw building data into actionable strategies using customizable reports and automated alerts. Whether you manage a single site or a global enterprise, the software scales to help you hit net-zero targets and lower utility expenses. It is designed for facility managers, sustainability officers, and energy consultants who need to prove ROI on their building optimization investments.
