Modbus / Re: More modbus "functions" or fewer (with multiple regs per)

Hi,
Yes it is much more efficient to read multiple registers a one time as there is quite an overhead in reading the registers one by one.
I wrote an article on using Modbus with Mach3. The concepts in it are also applicable for Mach4.
