How to control the start-up of each process has a certain interval at the node-red start-up

1.My flows have some server node,when the node-red start up,I hope i can define the Order and time interval of each flow,Is there any thing that can be done?
2.Is there a way to know the flow id of the current flow in the flow?

Flows do not start up until they receive a message or something like an inject node fires. Can you give an example of a flow that you want to delay?

for a example,this is a flow of opcua server,it will execute the process as soon as it is enabled, but I don't want that to be.

Your flow is not importable, please see this post for how to share a flow. However, when I said an example I did not really mean to share a flow, but a description of what an example does, what triggers it and why it should not start immediately.
