ime derivaTion example
Time is derived from the number of milliseconds since midnight.
Date can be derived from the number of days since midnight 1st Jan 1984.
If Modbus addresses 14720 thru 14724 (6 bytes) and the time is 09:50 and the date is 9th March
2015, then the SR55 will return: 021C49782C7E.
Where: 021C4978 = # milliseconds since midnight, and 2C7E = # days since 01/01/84.
Since there are 60 seconds in a minute, 3600 seconds in an hour, and 86400 seconds in a day,
the time can be derived as follows:
• 021C4978h = 35407992d (ms) = 35407 (s)
• Hour = 35407 mod 86400/3600 = 09
• Min = 35407 mod 3600/60 = 50
• Sec = 35407 mod 60 = 07
So the time is 09:50:07.
For the date the SR55 will only return the number of days since 01/01/84.
So: 2C7Eh = 11390d.
