HD67G07-2-B2 Modbus Slave to HTTP/REST Client RS232

HD67G07-2-B2 connects Modbus Slave RS232 devices with HTTP/REST Client communication via Ethernet.

HD67G07-2-B2 is an industrial ADFweb converter designed to connect devices operating as Modbus Slave on the RS232 side with systems and applications based on HTTP/REST Client communication. This model is a practical solution wherever classic serial communication must be integrated with modern Ethernet infrastructure and network-based data exchange.

From an integration perspective, HD67G07-2-B2 acts as a reliable bridge between Modbus Slave devices and an HTTP/REST Client environment. It fits well in industrial automation, telemetry systems, building automation and service applications where stable access to serial data through Ethernet communication is required.

The device is designed for industrial operation. It provides electrical isolation between Ethernet and power supply, 35 mm DIN rail mounting, a wide power supply range of 12..35V DC / 8..24V AC and an operating temperature range of -40°C to +85°C. The compact housing type B makes installation easy in control cabinets and retrofit projects, while the power consumption of about 5 W/VA at 24V DC supports straightforward panel power planning.

On the hardware side, the unit is equipped with 1 RS232 port with a 3-way 5 mm terminal block and 1 RJ45 Ethernet port. Ethernet communication works at 10/100 Base-T Autosensing, while the RS232 side supports transmission speeds up to 115200 bps. The manual also recommends using a Null Modem cable for RS232, with a suggested cable length not exceeding 15 meters.

The converter includes four status LEDs indicating device state, Modbus communication, HTTP/REST activity and error status. In case of firmware issues or configuration problems, the Recovery button can be used to switch the device into recovery mode and restore access for firmware update or reset procedures.

Configuration is performed using SW67G07, which allows the user to define HTTP/REST parameters, set the Modbus line, define the list of HTTP/REST servers communicating with Modbus masters, configure endpoints and update the device. This gives the integrator flexibility when adapting the converter to a specific industrial application.
