BLIIoT|New Version BL121 Modbus to OPC UA Conversion in Industrial 4.0

Introduction

A Modbus to OPC UA gateway allows for communication between devices that use different protocols. This is important because it enables interoperability and data exchange between different systems within an industrial environment. The gateway typically converts Modbus data into the OPC UA information model, enabling seamless integration and communication between devices from various manufacturers.

?

The advantages of using OPC UA over Modbus include improved security, reliability, and scalability. OPC UA uses encryption, authentication, and authorization to ensure secure communication between devices. It also supports complex data types and structures, making it ideal for the industrial IoT space. OPC UA is also scalable, meaning it can be used for both small and large applications.

Product Description

BL121 is a Modbus to OPC UA gateway that translates data between Modbus protocols and OPC UA (Open Platform Communications Unified Architecture) protocols. Modbus is a popular communication protocol used in industrial automation for connecting different devices, while OPC UA is a more advanced and secure protocol commonly used in the industrial IoT (Internet of Things) space.

?

By using a BL121 Modbus to OPC UA gateway, users can bridge the communication gap between devices that support Modbus and those that use OPC UA. This allows for interoperability and data exchange between different systems within an industrial environment. BL121 typically converts Modbus data into the OPC UA information model, enabling seamless integration and communication between devices from various manufacturers.
