The TLS (Transport Layer Security) Protocol in Secure Modbus/TCP

What is TLS and what is its role in the Modbus-TCP version of the Modbus protocol? Security comes with added protocol complexity. Many industrial control systems rely upon encapsulating Modbus Application Protocol (MBAP) Protocol Data Unit (PDU) messages carried on a TCP/IP network within a “TLS” layer to secure communications. The combined solution is called ‘Modbus/TCP … Read more

Design Strategies and Characteristics of Adaptive Machines

In this article, we take a look at adaptive machines and how they differ from traditional manufacturing techniques. With Industry 4.0 approaching, manufacturing processes and industrial control systems will change dramatically with adaptive machines set to become the next generation production method. The rapid growth of consumer product developments combined with changing consumer requirements is … Read more
