Books or Polish guides for learning GX IEC Developer with Mitsubishi PLCs?

Does anyone know about any book that teaches PLC programming based on GX IEC Developer and MITSUBISHI drivers or knows about the existence of other materials (guides to this software) in Polish (e.g. materials for students for automation laboratories)?
I want to try my hand at PLC on the example of GX IEC Developer. However, I am a beginner and I am looking in the dark. You can study literature in a foreign language if you know more or less what you are looking for.
Thank you in advance for any help

Hello

I don't want a new thread.

please decipher the functions
GX Developer:
MOV [D810Z0 D300]
exactly what does Z0 mean?

I found a description for the Q driver.
The next question is where the Z values are stored

Hello Z0 V0 are index registers, as the name suggests, are used to index devices in the controller
There are a lot of mitsu driver manuals on the web for details.

Among the driver registers there are also:
used for modification, index registers V and
FROM.
The V and Z index register is added to the other
device as follows:
[In this case, "V0, Z0 = 5"]
D100V0 = D105, C20Z0 = C25
