This document provides sample system architectures for building management systems using the Niagara framework. It shows how devices, controllers, servers and workstations can connect over various networks and protocols. The architectures allow for integration of building systems like HVAC, electrical, fire safety and more. They also enable remote access and analytics through cloud connections. Standard open protocols like BACnet, Modbus, MQTT and HTTP are supported for flexible integration.

DDC-V8044
DDC-V8044 is a16 base points (8UI, 4DO, 4AO), including 8 universal inputs (AI/DI), 4
digital outputs, 4 analog outputs, which is web page functions configurable.
Communication Protocol: BACnet IP/MSTP or Modbus TCP/RTU. Able to expands
several IO through it's expansion module (IO-V0800 or IO-V6002), or Remote IO
expansion module (IO-6020-485, IO-0800-485 or IO-0008-485). It can also be applied as
a Modbus Master, Master Bridge, Bacnet Router gateway.
