Rockwell Automation 1203 Serial Communications Module Series B - Manual (Page 58)

5–10
1203–5.5 September 1995
This example shows the response message N10:90 through N10:112
in both binary and ASCII. Note the ASCII information beginning
with N10:99. The parameter name characters return in reverse order
for each word. N10:99 has the ASCII value of (aM). To read this,
invert the word to read (Ma). The next word (ix), inverted 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 7 through word 14 of the response message. In addition,
word 20, is also returned in this format. This word provides the units
the parameter is defined in. In this example it is vlts.
Word 15 contains the file, group, and element which are used to
reference the parameter.
Words 16–18 contain the minimum, maximum, and default values of
this parameter.
