As energy efficiency and smart building management become a priority, the need to interconnect sensors, controllers and building management systems (BMS) is crucial. If your sensors or meters use the Modbus RTU protocol and your BMS is compatible with Modbus TCP , you can now connect these two systems thanks to our Milesight range of LoRaWAN controllers and gateways .
Why use LoRaWAN to bridge Modbus RTU and Modbus TCP?
LoRaWAN is a wireless technology that enables data transmission over long distances with minimal power consumption, making it an ideal choice for building infrastructure. Combined with Milesight solutions, the transition between Modbus RTU and Modbus TCP protocols is simplified, even in the most complex environments.
How the Milesight solution works
Our Milesight range of controllers and gateways allows you to connect Modbus RTU devices (such as energy meters, environmental sensors, or access controllers) to your BMS using the Modbus TCP protocol. Here's how it works:
1. Connecting sensors via Modbus RTU
Your sensors or meters are connected to a Milesight LoRaWAN controller . The latter converts Modbus RTU data into a LoRaWAN signal.
2. LoRaWAN transmission
The LoRaWAN signal is transmitted to a Milesight LoRaWAN gateway , which receives and processes the data.
3. Modbus TCP Conversion
The Milesight gateway then converts the data into Modbus TCP , enabling seamless integration with your BMS, ensuring optimized management and control of your building systems.
The advantages of this solution
Long distance connectivity
Thanks to LoRaWAN technology, it is possible to connect sensors located kilometers away from the gateway, without the need for complex cabling.
Energy savings
LoRaWAN is renowned for its low power consumption, thus extending the lifespan of field devices.
Interoperability
Using Milesight gateways and controllers, you can easily integrate devices using the Modbus RTU protocol into BMS systems compatible with Modbus TCP.
Reliability and scalability
Milesight solutions provide reliable data transmission and can be easily expanded to new equipment or sites as your needs evolve.
