Example
In this example, a reference time stamp data read was requested
through the PMW. Word 2 of the PMW defines this request with a
decimal value of 2816 for the PLC command code. The PMR
response indicates a successful request with a returned value of 2816
in PMR word 2. Words 4 through 7 then return the clock data. The
clock data indicates a time stamp of February 1995, the fifth day of
the week (Thursday), and a date of 23 (17 in ASCII). The hour,
minutes, and seconds change according to the time.
