This documentation provides users with a high degree of confidence that a PLC will consistently provide control information or data that meets predetermined specifications. It requires extensive documentation, including procedures, test data, summary reports and certification forms. PLC validation is a legal requirement in some industries such as drug manufacture, where product quality is particularly important. OPC UA also has sophisticated security that authenticates clients and servers to ensure the integrity of their communications. It uses an integral information model, meaning that an organization can model its data into a namespace to take advantage of OPC UA’s service-oriented architecture (SOA). OPC UA allows industrial equipment and systems to communicate with each other, generally for the purposes of control and data collection. Furthermore, OPC UA has an open source, so it can be used without fees or restrictions. OPC UA is platform independent, meaning that it doesn’t require a particular operating system or programming language. Key industries using this protocol include manufacturing, pharmaceutical, industrial robotics, building automation and oil & gas. It was developed by the OPC Foundation, which currently has over 35 collaborations. OPC UA is a machine-to-machine communication protocol for industrial automation. Visual Components provides an interface for OPC UA that allows users to perform PLC validation by connecting a simulation to external controllers. OPC UA overcomes the limitations of OPC Classic to increase productivity, improve quality and lower costs. PLC validation often relies on OPC Unified Architecture (UA), which is the latest OPC technology. This process consists of three phases, which include defining the functions that the PLC must perform, building a PLC that performs those functions and proving the PLC behaves as intended. PLCs are commonly used in manufacturing processes, especially robotic devices on assembly lines.Ī PLC’s design must be validated before it can be used. A programmable logic controller (PLC) is a specialized type of computer designed for applications requiring high reliability, ease of programming and sophisticated fault diagnosis.
