4–17 Using Unscheduled Messaging
Publication 1336 FORCE–5.18 ––March, 1999
This example shows the response message N7:90 through N7:112 in
both binary and ASCII. Note the ASCII information beginning with
N7:99. The parameter name characters return in reverse order for
each word. N7:99 has the ASCII value of eV. To read this, invert the
word to read Ve. The next word (space)l, inverted gives you
l(space). These words, along with the following two words, form the
word “Vel_” The parameter name Vel Ref1Hi can be seen in words
10 through 17 of the response message. In addition, word 23 is also
returned in this format. This word provides the units the parameter is
defined in, which in this example is “RPM”.
Word 18 contains the file, group, and element which are used to
reference the parameter.
Words 19 through 21 contain the minimum, maximum, and default
values of this parameter.
