The Modbus Master example reflects how a mesh router in RIIM can act as a Modbus master, read out data from one or more Modbus/RTU slaves, and send read data through the RIIM network.
In this example the addressing, CRC generation and CRC check are handled locally in the mesh router. This means that a local intelligence in the mesh router is needed to determine which data to send, how often to read the sensor, and more.
Wireless technologies are frequently considered unreliable for industrial and building automation systems, plus, these systems often require downlink functionality and battery-operated equipment. RIIM proves to be an excellent solution to these problems for many reasons:
- RIIM supports Time Synchronized Channel Hopping (TSCH) which provides a proven reliability of 99.99% or higher.
- RIIM supports symmetrical 2-way communication to easily send data up and down the network and for Over-The-Air updates.
- RIIM has long range to easily cover a massive building complex as large as 5.6 km², 3.5 mi².
- RIIM is very low power for battery-operated devices. The RIIM Mesh Router can handle down to 118uA at 3.3v average power consumption enabling all battery devices in the network to further extend the network coverage.
