A Building Management System (BMS) diagram is a visual representation of a building’s automated systems. It is a schematic diagram that shows the various components of the system, how they are connected, and how they interact with each other. The diagram also includes information about the various types of equipment used in the system, such as sensors, controllers, and actuators. The diagram can also show the various communication protocols used in the system, such as Ethernet, Wi-Fi, and Bluetooth. The diagram can also include information about the system’s security measures, such as firewalls, intrusion detection systems, and access control systems. By looking at the BMS diagram, it is possible to quickly identify any potential problems or issues with the system, and take corrective action to ensure that the system is running smoothly. A BMS diagram is an invaluable tool for any building manager or engineer, as it allows them to quickly and easily identify any potential issues with the system, and take corrective action to ensure that the system is running optimally.
