An OPC UA FX Descriptor defines the information for using and configuring one or more AutomationComponents. This information may contain data provided by the vendor of the AutomationComponent or configuration data produced by Controls Engineers in the OfflineEngineering phase.
A Descriptor is a digitally signed multi-document file (AML Container) containing Information Model files in the AutomationML language and other artefacts such as manuals, drawings, product pictures, binary files, certificates for authorship and conformance, etc. This is shown in Figure 5.
