I’m having trouble reading the UDT parent type of a UDT instance using the system.tag.readBlocking function. The old system.tag.read function still works, but system.tag.readBlocking returns None.
Here is some example code.
path_to_udt_instance = "[default]some_tag_path"
print system.tag.read(path_to_udt_instance+".udtParentType").value
print system.tag.readBlocking([path_to_udt_instance+".udtParentType"])[0].value
