The configurable gateway HD67933-B2 enables communication between Modbus RTU slave devices and an MQTT broker (server). Communication is bidirectional, so that it is possible to read data from Modbus RTU slave devices and write data to Mobus RTU slave devices. The gateway can send(Publish) the data read from Modbus RTU to configurable topics to MQTT broker(Server) and receive(Subscribe) configurable topics to write this data to the Modbus RTU. On the MQTT side, it is possible to use TLS / SSL encryption to have a secure connection to the MQTT broker. Transferring the configuration that you have previously created with the free SW97933 configuration software is very easy and quick via the Ethernet port. The DIN rail mounting and screw terminals guarantee quick and secure installation and easy wiring of the device
