Product description¶
W-Modbus simplifies Modbus RTU installations by replacing the control cable with a wireless connection. This significantly alleviates the downsides of running control cables, such as daisy-chaining, installation planning and troubleshooting.
The W-Modbus module is built on LumenRadio's MiraOS, which runs the MiraMesh network stack. MiraMesh is a self-stabilizing mesh network technology that uses patented technology to ensure highly reliable, and long-range wireless communication in noisy environments. W-Modbus uses the international license-free ISM band at 2.4 GHz, the same band used by WiFi and Bluetooth. But thanks to Cognitive Coexistence, our patented technology, our devices communicate reliably despite the noise generated by nearby devices.
A W-Modbus unit can be configured either as a Gateway that is connected to a Modbus Client, or as a mesh node that is connected to one or more Modbus Servers. A W-Modbus network can consist of up to 100 mesh nodes.
Features¶
- Mesh Network – Cover an entire building by utilizing the mesh network as your infrastructure.
- Self-stabilizing – The mesh network will continually search for the best route for packets between each device.
- Cognitive Coexistence – LumenRadio's patented technology provides industrial- grade reliability and tolerance to interference.
- Agnostic Communication – No need to have identical baud rate, parity, or stop bit configuration on each Modbus device in the same network.
- Small footprint – 18.5 mm x 33.5 mm.
- Antenna Connector – U.FL/IPEX.
-
Upgradable Firmware – Via BLE (Bluetooth Low Energy). - Multiple Modbus Devices – Up to 16 Modbus slave devices per W-Modbus Pro module in mesh mode.
-
Configurable via UART or SPI.
