BACE Modbus Gateway + IoT Connector


BACE Modbus Gateway + IoT Connector


The IoT solution that allows to remotely access and manage your Modbus data via the cloud.

BACE Modbus Gateway is a ready-to-use, quick to deploy solution that can be configured remotely through a portal, to read and write exactly the Modbus registers of your choice, at the frequency you specify, in a reliable and secure way. 

How does it work?

BACE Modbus Gateway accomplishes remote Modbus management by pairing the BACE module with a Device Twin in the cloud. The Device Twin delivers a digital replica of the BACE module that enables you to see the state of the device and the Modbus registers. If the module is connected to one or more Modbus devices, it will retrieve the data, and send it directly to the Cloud through the LTE-M or 2G network.

Fully integrated with Azure, the IoT connector uses IoT hub, Device Twin, and Device Provisioning Service.

Connection and Installation

BACE Modbus Gateway is able to connect via a serial connection (RTU) as well as through a TCP/IP network. The data is constantly provisioned to your systems via the API of the BACE IoT Connector. The API follows an OAuth 2 Model for encryption, authentication and authorization, and has diverse access levels. BACE can also offer Webhooks, like event based automated messages that can be sent to your system anytime an event occurs.

BACE’s installation requires little effort. It is sufficient to connect the module to the Modbus, and its power cord to a 230V or 120V power supply. All this can be done by a technician without special training. Once installed, you can remotely configure from your desk through the Device Twin using tools in the BACE operation portal.


To protect your data and information, and to secure the IoT system, BACE Modbus Gateway has a Secure Element and uses a state-of-the-art IoT security mechanism. This mechanism has been developed by Microsoft and Microchip, and is centered on protecting both the hardware and software of each device. This secure technology contains the individual encryption certificate of each specific module and is protected from physical break-ins. In case of a forced attempt, the element destroys itself and the certificate, preventing any subsequent access to other parts of the system.

Additional features
