The MC Protocol node can request more than 1 thing at a time. This is documented in the built in help.

NOTE: Addresses must be in the same device area (memory area).

NOTE: Even if you want DM1, DM30 and DM99 - it is STILL quicker (and better, for consistency) to request 1 lot of 100 things than it is to make 3 separate requests

Here is an article I wrote explaining why: [Modernize your legacy industrial data. Part 2. • FlowFuse](https://flowfuse.com/blog/2023/09/modernize-your-legacy-industrial-data-part2/)

PS: the buffer-parser node can help with data conversions and pulling the items out of the data in a no-code graphical manner.
