Hybrid gateway (ext. power, Din-Rail)

Description

The Lobaro Hybrid Gateway ext. Power, DinRail with Modbus is an easy-to-use, cost-effective and energy-efficient device that reads data via Modbus from any number of Modbus-enabled devices, stores it temporarily and forwards it to the Internet.

The gateway can be used for communication with Modbus slave devices (ASCII/RTU on an RS-485 bus, TCP on via Ethernet) via NB-IoT, LTE-CatM1, LoRaWAN or LAN. Modbus commands can be transmitted to the gateway via downlink message and are forwarded by the bridge to the connected slave devices. Received responses are forwarded as uplink messages to the Lobaro IoT Platform. The Modbus gateway can also be configured to regularly execute Modbus commands and report the responses at the time of execution.

The Modbus gateway supports reading all four register types that can be provided by Modbus slave devices: Coil, Discrete Input, Input Register, and Holding Register. It also supports writing values to all writable registers: Coil and Holding Register. Several different slave devices on the bus can be accessed individually from a single gateway device, even if the slave devices have a different Modbus configuration. In order to fulfil individual requirements, read intervals and register definitions can be configured very flexibly.

In normal operation, all actions of the device are controlled by an individually configurable scheduler, which executes the list of jobs in sequence. Only one job is executed at a time. The jobs generate uplink messages that are uploaded. After each uplink sent, the device searches for downlinks coming from the network (this happens for both LoRaWAN and LTE configurations). Downlink Modbus commands are currently only supported for LoRaWAN.

In addition, it is possible to read consumption values from up to 500 commercially available water meters, heat meters, heat cost allocators or similar with 868 MHz wireless M-Bus radio interface (e.g. OMS compatible meters) or Sensus RF Bubble Up and forward them encrypted via mobile radio or LoRaWAN to the Internet for further analysis.

The daily status uplink ensures that the device can be reached for remote configuration within 24 hours, regardless of the current configuration.
