示例1: parent
# 需要导入模块: from opcua import Server [as 别名]
# 或者: from opcua.Server import create_custom_event_type [as 别名]
# setup our own namespace, not really necessary but should as spec
uri = "http://examples.freeopcua.github.io"
idx = server.register_namespace(uri)
# get Objects node, this is where we should put our custom stuff
objects = server.get_objects_node()
# populating our address space
myobj = objects.add_object(idx, "MyObject")
myvar = myobj.add_variable(idx, "MyVariable", ua.Variant(0, ua.VariantType.Double))
myvar.set_writable() # Set MyVariable to be writable by clients
# Creating a custom event: Approach 1
# The custom event object automatically will have members from its parent (BaseEventType)
etype = server.create_custom_event_type(2, 'MyFirstEvent', ua.ObjectIds.BaseEventType,
[('MyNumericProperty', ua.VariantType.Float),
('MyStringProperty', ua.VariantType.String)])
# create second event
etype2 = server.create_custom_event_type(2, 'MySecondEvent', ua.ObjectIds.BaseEventType,
[('MyOtherProperty', ua.VariantType.Float)])
myevgen = server.get_event_generator(etype, myobj)
myevgen.event.Severity = 500
myevgen.event.MyStringProperty = ua.Variant("hello world")
myevgen2 = server.get_event_generator(etype2, myobj)
myevgen2.event.Severity = 123
myevgen2.event.MyOtherProperty = ua.Variant(1.337)
serverevgen = server.get_event_generator()
