Adressing the RDM

All RDM devices have a UID preprogrammed into them that is like a unique electronic serial number. This is how they are discovered by an RDM Controller.

The DMX Address of the device can be changed, but the UID can not.

2. After installing such lighting fixtures is that they can identify and where it is placed where it is if you have to evaluate visually?

There is a command you can send to a device for it to visually identify itself.

3. How they are recognized when connected to the RDM controller?

The controller goes through a discovery process that finds all the connected RDM devices by their UID.

4. Is it possible to create a virtual map of their location?

The controller can discover them all, it is up to whatever controller you are using in how it presents this information to the user.

Could you tell us more about this? What are the commands?
How do they work?

The controller can discover them all, it is up to whatever controller
you are using in how it presents this information to the user.

Whether it is possible to see eg. 1000 luminaires in the form of a matrix with
the exact location of the housing with the UID?
Do you recommend a driver who knew how to do it?
What software you recommend?

The specific command is IDENTIFY_DEVICE. It is all documented in the standard itself as to how the protocol all works. Every controller presents it differently to the user depending on the design of the UI.

It is possible for a controller to implement it as you suggest, it just depends on the specific controller. I don't have any recommendations on which one to use though.
