Summary0007632: Defined VariableTypes should be removed - they just add complexity but are not necessary
Description

What is the benefit of the VariableTypes PublisherCapabilitiesType, SubscriberCapabilitiesType, ServerAddressType, SecurityKeyServerAddressType?

It makes the implementation much more complicated and there is no benefit for clients since they need to handle complex types anyhow since they are contained in the sub-variables.

Arguments for VariableTypes in addition to DataTypes:

  • Support simple clients that are not able to display complex types (not relevant since the sub-variables still use complex types)
  • Monitor single fields of a structure - not relevant, the information is not frequently changing
  • Write single elements of a structure - not relevant since most of the data is readonly or is changed only by one client (locked)

I would strongly recommend to delete the VariableTypes and to define only the DataTypes.

TagsNo tags attached.

Initial discussion is that capabilities might be better as an object type and no structure

the other two might need more explanation - where the selection list is obtained from (engineering tools)

Converted the PublisherCapabilitiesType and SubscriberCapabilitiesType to Object types and removed the Datatype. This information did nto need to be read as a single unit and thus did not need the datatype.
Additional text was added to explain the ServerAddressType and SecurityKeyServerType and there use of a datatype to go with the Varaibale. This data is updated by general OPC Ua clients and ten used (passed) always as a structure.
