PLC-5 Read/Write Time Registers
The DTAM Plus reads and writes the time to the following fixed registers.

S:18 Year
S:19 Month
S:20 Day
S:21 Hours
S:22 Minutes
S:23 Seconds
SLC Read/Write Time Registers
The time data register is a 16 bit integer format. Time/Date data is stored in
each of the eight sequential registers as shown below. The register locations
are defined by the Time Base Register (see previous page).
Location Time Data
1 Seconds 0-59 (Decimal)
2 Minutes 0-59 (Decimal)
3 Hours 0-23
4 Day (Week) 1-7 (Sun - Sat)
5 Day (Month) 1-31
6 Month 1-12
7 Year 1980-2079
8 AM/PM 0 or 1
(Bit Designation)
Note: Synchronization can’t occur if the base register is zero (such as N7:0).
SLC 5/03 Time Synchronization
Do not use S:37 as base register for a clock sync read or write. The
SLC-5/03 locations S:37 through S:44 have a different sequence of data than
DTAM Plus locations 1 through 8 as shown below. For example, set the base
register to N7:10 and then use ladder programming to move each data
location to the time/date status words.
