In E1.20, the details of how and when to do discovery are left up to the implementer. Some RDM controllers do constant ongoing discovery, others do discovery only at startup or when requested by the user.

The same applies to E1.33: It's implementation specific.

I suspect many controllers will send the INITIATE_DISCOVERY PID when they startup, then poll the "Discovery State" field to know when it's complete. But this is not required.

Polling intervals are also implementation specific. Some will get a device list once and use it forever, others will poll every few seconds. It's a matter of what best fits the target market.
