In the following two examples the keywords that are not recognized are 'Reset T' and 'Tripout'
respectively

In the following example the keyword '********' is not being recognized. If this message is printed
it is necessary to consult Carrier Corp. to learn why a variables’ value is printed as '********'. It
may be that the value is over range or invalid.

Extending the List of Discrete State Words
You can extend the list of state words the driver recognizes by modifying the configuration CSV
file.
The following example adds three state words. If a device reports the state of the variable as
LIGHT then the driver will store the value of 1, if on the other hand the state is reported as DARK
then the driver will store the value zero.

This method may be used to change the values of any of the driver’s default state words by
duplicating the word and specifying a new value in the configuration file.
Appendix A.4.2.
Time Values
If the driver receives a variable value reported in the format hh:mm then the driver stores a
number obtained by multiplying the hours by 60 and adding the minutes. The driver recognizes a
time value by checking the 3
number obtained by multiplying the hours by 60 and adding the minutes. The driver recognizes a
time value by checking the 3
rd
character for a colon and checking that the 1
st
character is a digit.
Value_Stored = hh * 60 + mm
E.g. 5:30pm is reported as 17:20 and is stored as 17*60 + 20 = 1040.
