Standardisation by means of OPC UA

OPC UA (Open Protocol for Communication Unified Architecture) is a communication standard designed to ensure interoperability in networked production. This ensures that machines, peripheral devices and cloud-based internet applications can communicate with each other without interference. OPC UA helps standardise horizontal communication between machine and machine (M2M), and vertical communication from the machine to data storage and evaluation. It is irrelevant which manufacturer, which programming language or which system supplier is behind the machine. OPC UA is an open interface standard.

Requirements for use

Controls and devices

More and more controllers and devices provide OPC UA directly as a communication protocol. For others, there is the conversion of proprietary protocols to OPC UA with corresponding OPC servers.
Every machine, every sensor and every other system that provides OPC UA data must be connected in the same way.
If the machine data of an older system is important information, a lot of data can be collected by small controllers (this must be retrofitted).
