The invention relates to a method for configuring a component of a subsystem of an industrial
plant, the component comprising an OPC UA
server and an OPC UA
data model comprising attributes of the component, the method comprising the following steps: an OPC UA
client of a mapping tool selecting the OPC UA
server of the component; the OPC UA
client receives an OPC UA
data model including an attribute
list from the OPC UA
server; the mapping tool retrieves a parameter
list from an
engineering database related to the component; the mapping tool retrieves a
list of relationships between attributes of the OPC UA
data model and component parameters from dictionaries in a dictionary
database; for each attribute, the mapping tool checks whether the dictionary contains a relationship from the relationship list including the attribute; for each relationship including the attribute, the mapping tool adds the relationship to a mapping definition file; the mapping tool adds parameters to an
address space of the OPC UA server by using the OPC UA
Reference Type HasDictionaryEntry on the basis of the mapping definition file so as to configure the component; and an OPC UA
client of the
control unit PLC reads the parameters of the components.
