HD67G10-G43-E-B2 Modbus TCP Master to HTTP/REST Server converter with LTE and eSIM

HD67G10-G43-E-B2 connects Modbus TCP Master devices with HTTP/REST Server communication via Ethernet, SIM LTE and eSIM.

HD67G10-G43-E-B2 is an industrial ADFweb converter designed to integrate systems using Modbus TCP Master with applications and services based on HTTP/REST communication in server mode. This model has been developed for environments where industrial Ethernet communication must be combined with modern data publishing for supervisory systems, web applications, software platforms and network services.

The HD67G10-G43-E-B2 variant offers LAN + SIM LTE + eSIM connectivity, allowing the device to operate both in local networks and in distributed applications where a mobile data channel is required. It is a practical solution for automation integrators, telemetry systems, building installations, technical monitoring and service applications in which data read from Modbus TCP devices must be made available through an HTTP/REST interface for external systems.

The manufacturer confirms that the device provides electrical isolation between Ethernet and power supply, mounting on a 35 mm DIN rail, a wide power supply range of 12..35V DC / 8..24V AC and an operating temperature range of -40°C to +85°C. This specification makes the converter well suited for control cabinets and demanding industrial environments where stable operation, compact housing and simple installation matter.

The HD67G10-G43-E-B2 model is equipped with 1 Ethernet RJ45 port, a SIM slot and built-in eSIM. The manual states that the G43 version uses an LTE module, features an SMA Female antenna connector and works with a Micro-SIM card. The Ethernet port is used for device programming as well as for HTTP/REST and Modbus TCP communication, which simplifies integration and commissioning.

From a networking perspective, an important feature of the device is the use of two different MAC addresses: one dedicated to the HTTP/REST side and one dedicated to the Modbus TCP side. Communication on both sides works in the 10/100 Base-T Autosensing standard. The manufacturer recommends using at least a Category 5E cable compliant with the T568 standard, and the maximum Ethernet cable length should not exceed 100 m. This makes it easy to integrate the converter into existing industrial network infrastructure.

The HTTP/REST layer allows the definition of a list of accessible endpoints available to external applications through GET and POST methods. GET is used to read data coming from Modbus TCP, while POST is used to write data to Modbus TCP devices. The configuration software also allows username and password protection, operation in HTTP or HTTPS mode and the upload of a custom TLS certificate.

The converter includes four LEDs that indicate the operating status of the device. The first LED shows device state, the second indicates Modbus TCP communication activity, the third indicates HTTP/REST communication activity and the fourth shows error status. In addition, the module is equipped with a Recovery button, which allows the device to enter recovery mode after a wrong firmware update or configuration issue, making service and restart easier.

Configuration is performed using SW67G10, which allows the user to define HTTP/REST parameters, Modbus TCP settings, the list of accessible endpoints on the HTTP/REST side and the list of Modbus TCP read and write requests. The software is also used for device updates and adaptation of the converter to a specific industrial application.
