Does Niagara support Modbus TCP/IP?

Yes, the Niagara Framework supports Modbus TCP/IP protocol. The Niagara Framework includes a Modbus driver that allows it to communicate with Modbus devices using the TCP/IP protocol. This allows for the integration of Modbus devices, such as PLCs, into a Niagara-based building automation and control system. The Niagara Framework can also map Modbus registers and coils to Niagara points, making it easy to access and control Modbus devices from within the Niagara system.

It is also worth noting that the Niagara Framework also supports other protocols such as BACnet, LonWorks, and OPC, which allows it to connect to a wide range of devices in building automation systems.
