SmartNova DDC — Controller Functionalities
FAQ
DDC Controller — Frequently Asked Questions
What is a DDC controller?
DDC stands for Direct Digital Controller. It processes analogue and digital signals from field sensors and actuators to control HVAC, lighting and other building systems. The EnSmart EN-CPU-V7 runs on the SmartNova platform with an ARM A53 processor, native BACnet/IP and Modbus TCP, and automated IO-to-commissioning engineering.
What protocols does the EN-CPU-V7 support?
BACnet/IP, Modbus TCP, Modbus RTU (RS485, master / slave), MQTT and REST API. It also converts Modbus RTU / TCP to BACnet/IP and MQTT, and BACnet/IP to MQTT.
Does the EN-CPU-V7 need a separate BACnet gateway?
No. BACnet/IP runs natively on the controller over its Ethernet port, per ISO 16484 / ASHRAE 135. Modbus devices on its RS485 ports can be exposed as BACnet objects to any BACnet BMS without extra gateway hardware.
How many IO modules can the EN-CPU-V7 connect?
Each of its three RS485 ports supports up to 15 EN-series IO modules, alongside third-party Modbus devices. The total IO point count depends on the modules selected, from the 16-input EN-16DI to mixed modules such as the EN-4DIAI3DO2AO.
How is SmartNova different from other DDC controllers?
Native BACnet/IP with no gateway, MQTT and REST API built in, ECBC 2017 sequences preloaded, same-day engineering from IO list to wiring drawings, configuration with the free EnSmart Editor tool, on-site IO module replacement without re-programming, and manufacturing in India with local support.
What power supply does the EN-CPU-V7 need?
A 12–24 V AC/DC supply, such as a 230 V AC to 24 V DC SMPS. The controller is rated at 30 W; size the supply for that plus any other connected loads.
Where is a DDC controller installed in a building?
The EN-CPU-V7 mounts on DIN rail inside a closed control panel, protected from dust, water and direct sunlight, within 0 °C to 50 °C and 0–95 % RH. It typically sits in plant rooms or AHU and chiller panels, close to the equipment it controls.
