Web Services make us of a very distinct description language, which is WSDL (i.e. Web Service Description Language). The OPC Router reads WSDL descriptions directly – with no detours – and presents the strucutre of the Web Service.
The WSDL description contains a list of functions contained in the Web Service. This list is made available for individual selection.
Functions have parameters and return values. In addition to simple types, both can also contain complex structures, array and arrays of complex structures. All variants are supported by the OPC router and listed for selection.
