OPC servers serve as an interface between the measuring instrumentand the central building control system or PLC in these cases.OPC drivers, therefore, offer a standardised interface for easy data exchange without exact knowledgeabout the communication options in the counterpart system.The OPC can be used to link the measurement data with the data from other trades and archive itin the database structures for process control techniques. OPC drivers for process control techniquesare used by almost all renowned manufacturers of building automation systems.154
