BMS CONNECTION – FULL DETAILS | Smart Automation & Control
A Building Management System (BMS) integrates all building services into a centralized control platform, enabling efficient monitoring, automation, and optimization of MEP systems. Proper connection and system architecture are key to achieving reliable and intelligent building performance.
📌 BMS System Architecture:
BMS Workstation → Application Server → Database Server → Network Switch → DDC/Field Controllers → Field Devices
All components are connected through Ethernet TCP/IP network ensuring fast and reliable communication.
⚡ Electrical Panel (Power Distribution):
• MCCB / MCB for protection
• Contactors & Relays for control
• Power Supply Units
• Terminal Blocks & Wiring
• Surge Protection Devices
This panel provides safe and stable power to all BMS control systems.
🧠 DDC Panel (Control Panel):
• DDC Controller (brain of BMS)
• Input/Output Modules (AI, AO, DI, DO)
• Communication Modules (BACnet/Modbus)
• Power Supply & Terminal Blocks
• Structured Wiring & Panel Accessories
DDC panels collect field data and execute control logic.
