The BSI has investigated the security of OPC UA and found no systemic security gaps. In this way it can be controlled which client is allowed to connect to the server. OPC UA uses a certificate exchange for further security, so that each client has to authenticate with a certificate. This reduces multi-access from the data source, and hence reduces the load on the data source. Why do we need OPC server?Īn OPC server reduces the load on data source devices as it enables communication with several applications, while having only one connection with the data source. It is platform-independent and ensures the continuous flow of information across multiple vendor devices. OPC is a software interface interoperability standard that allows secure and reliable exchange of data between Windows programs and industrial hardware devices. OPC standard is implemented in server/client pairs. OLE is based on the Windows COM (Component Object Model) standard. The acronym “OPC” stands for “OLE (Object Linking and Embedding) for Process Control”. OPC is a widely accepted industrial communication standard that enables the exchange of data between multi-vendor devices and control applications without any proprietary restrictions. One application acts as the server providing data, and the other acts as a client using data. PLCs vs LabVIEW? Well, a PLC is a hardware controller, and LabVIEW is software, so they’re quite different.
