Message Operation
The Warning Queue Entry Read Full function specified in the PMW
reads the contents of the warning queue specified in word 3 of the
PMW message. The response returns the warning text which can be
shown as ASCII text. The text will have every two characters in
reverse order and return a time stamp indicating the day and time the
warning occurred. The Clock Time is returned in the order shown in
the header message. You should view this information as ASCII text.
This field:
Indicates:
Day
The day of the week, where 1 is Sunday and 7 is
Saturday.
Year
The number of the year. 1990 is referenced as 0.
Therefore, the year 1995 would return a value of 5.
Month
The month of the year, where 1 is January and 12 is
December.
The Date and Time are in hexadecimal format.
