The purpose of the subscription is to monitor writable nodes for changes and then to write those changes to the OPC-DA server. On the first line, the SubscriptionHandler class is instantiated with n=len(writeable_variable_handles), so n is really just the number of monitored variables. Sub = server.create_subscription(100, handler).subscribe_data_change(writeable_variable_handles.values()) Handler = SubscriptionHandler(len(writeable_variable_handles)) The error points to tree = parent.add_folder(idx,folder) in my case.Īlso, to avoid any other issues, I'm just passing the following nodes to the for loop. ValueError: A LocalizedText object takes a string as argument, not a, Random
