I am taking 3 mc protocol node for 3 address,but I have 100 address so not possible every address assigned single node , please help how to get multiple address in one function or how to managed?
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
PS: the buffer-parser node can help with data conversions and pulling the items out of the data in a no-code graphical manner.
