hello all:
I was wondering if someone might be able to help. I have been confused for several days.
I write a OPC server and want to read a UDT tag.Firstly I want to
use the Get Attributes List Service(0x03) to get some information for the template ,however i don't know how to get the instance number of the template,and the attribute ID information .
anyone can help me ,thanks a lot.
