Well in general every driver woul get the request with all tags. However it's highly dependent on the protocol how they handle that. We therefore have so called "Optimizers" that can intercept and rewrite them before passing them to the protocol logic. The modbus and s7 drivers have very advanced ones. The SPI contains a universal one that makes single item requests out of multi item requests.

Please have a look at those.
