Introduction to BECSys5 BECSys5 (Building Energy Control System 5) represents the fifth generation of integrated building management systems (BMS) designed for mid-to-large-scale commercial and industrial facilities. Unlike legacy systems that rely on fragmented hardware and proprietary communication protocols, BECSys5 is built on a fully converged IT/OT architecture, supporting BACnet/IP, Modbus TCP, MQTT, and RESTful APIs. | Block | Function | Example Use |
For advanced use cases—such as integrating Modbus RTU meters, setting up BECSys5 in a redundant failover cluster, or writing custom Python scripts inside the automation engine—refer to the (available as a separate download). | Terminal Block | Signal Type | Example
| Terminal Block | Signal Type | Example Device | |----------------|-------------|----------------| | AI1–AI8 | 0–10V or 4–20mA (jumper select) | Temp sensors, pressure transducers | | DI1–DI8 | Dry contact, 24VAC/DC | Status, flow switches | | AO1–AO4 | 0–10V (10mA max) | Valve actuators, VFD speed ref | | DO1–DO6 | Relay, 2A @ 30VDC/250VAC | Pump start, lighting contactors |
Maximum trunk length: 1200m at 76.8kbps. The BECSys5 installation and technical manual provides the foundational knowledge required to deploy a robust, scalable building automation system. Following this guide ensures that hardware is mounted correctly, networks are segmented, points are logically organized, and the system is hardened against cyber threats.
