As the two parameters have a resolution of a decimal place for writing of 1.0
and 2.0 seconds, thus the values 10 (000Ah) and 20 (0014h) should be
transmitted.

Function 16 - Write
Multiple Registers
This function allows writing values to a register group that must be in
numerical sequence. This function can also be used to write a single
register(thevalues arealwayshexadecimalvaluesandeach field represents
one byte).
