DataSetManager with OpconXml and public interface

Hello,

I would like to ask some implementation questions about PLC side, when use setup control of MES.

1.Should I configure the OpconXml in the DataSetManager ?

2.If select OpconXml, the DDL events will be sent by DataSetManagerAddon automatically  during executing load data command  or I need to create DDL events based on the xml file exported by Cpstudio?

3.if it is sent automatically, where can I find the structure 'DataAccessHead' and assign specific value, for example: type number

 

another question about public interface:

is it possible to use the xml and OPC UA at the same time? I mean telegram use xml, DatsSetManger use public interface

thank you~
