If communicating with Mach3 CNC software and write to multiple Analog Outputs reg. cant get respons from library #2

If communicating with Mach3 CNC software (ower USB) and write to multiple 
Analog Outputs reg. then can't get answer from modbus library.

Mach3 sends hex: 01 10 00 00 00 05 0A 00 00 00 00 00 00 00 00 00 00 01 F8, (10 
reg.) but no responds. Is this function implemented?

write to single Analog Outputs (01 06 ....) works.
Reading Analog Inputs with Mach3 works.

I use Arduino Micro.

Greetings,

Great project! 
One small issue I found was that when using an HMI, I could only read address 0 
when I used 1 for register.  Any other 30001 or 40001 and even 10001 were not 
found and a zero was located at those addresses.  I even used the test program 
that creates random numbers in some of those registers and only saw a random 
number at address 0.  Hopefully, my Arduino Uno was not at fault.  Other than 
that, it worked flawlessly once I got the hardware issues out of the way.

Again,

Thanks and good luck.

RC
