This example shows the response message in both binary and ASCII.
Note the ASCII information beginning with word 9. The parameter
name characters return in reverse order for each word. Word 9 has the
ASCII value of (aM). To read this, reverse the word to read (Ma). The
next word (ix), reversed, gives you (xi). These words, along with the
following two words, form the word Maximum. You can see the
parameter name Maximum Voltage in word 9 through word 16 of the
response message. In addition, words 21 – 22 are also returned in this
format. These words provide the units in which the parameter is
defined. In this example it is vlts.
Word 17 contains the file, group, and element which are used to
reference the parameter.
Words 18 – 20 contain the minimum, maximum, and default values of
this parameter.
