MODBUS: “interface for Modbus slaves”

MODBUS: “interface for Modbus slaves”

LoRaWAN sensor

Query, write and read one or more registers on one or more Modbus slaves

The MODBUS IoT sensor meets the needs of users wishing to interrogate one or more MODBUS slaves and send back their information via an LPWAN network.

The product uses the MODBUS Remote Terminal Unit (RTU) protocol to communicate with the slaves.

Highlights of the IoT sensor

RS485/RS232 compatible
Supervision of up to 20 slaves
Several periodic frames with different frequencies
Indicator lights for installation assistance
Control and supply of power to the sensor
Local and remote configuration
Compatible with KARE services
Available versions: LoRaWAN EU863-870 / US902-928 / AS923-1
