The <strong>T1</strong>-<strong>16S</strong> enhanced model is equipped with the real-time clock/calendar for year,<br />
month, day, day of the week, hour, minute, and second.<br />
These data are stored in the special registers SW07 to SW13 by 2-digit BCD format<br />
as follows.<br />
Register Function Data<br />
SW07 Year 1999 = H0099, 2000 = H0000, 2001 = H0001, 2002 = H0002 ...<br />
SW08 Month Jan. = H0001, Feb. = H0002, Mar. = H0003, ... Dec. = H0012<br />
SW09 Day 1st = H0001, 2nd = H0002, 3rd = H0003, ... 31st = H0031<br />
SW10 Hour H0000, H0001, H0002, ... H0022, H0023<br />
SW11 Minute H0000, H0001, H0002, ... H0058, H0059<br />
SW12 Second H0000, H0001, H0002, ... H0058, H0059<br />
SW13 Week Sun. = H0000, Mon. = H0001, Tue. = H0002, ... Sat. = H0006<br />
Program example:<br />
In the following circuit, output Y030 turns ON for 1 minute at every Sunday 6 pm.<br />
(H0018)<br />
Clock/calendar back up:<br />
The clock/calendar continues updating even while the power to the <strong>T1</strong>-<strong>16S</strong> is off by<br />
built-in capacitor and by the optional battery (CR2032) if used. Its buck-up period is as<br />
follows.<br />
Environment<br />
Expected value Guarantee value<br />
temperature Capacitor Battery Capacitor Battery<br />
Under 30 °C (86 °F) 2 hours 2 year 1 hours 1 year<br />
Over 30 °C (86 °F) 1 hours 1 year 30 minutes 6 months<br />
As shown in the table, it is recommended to use the optional battery when the realtime<br />
clock/calendar function is used.<br />
In the <strong>T1</strong>-<strong>16S</strong>, the validity of the clock/calendar is checked. If the data is not valid by<br />
excess power off period, special relay S00A is set to ON. Therefore, when the<br />
clock/calendar is used, it is recommended to check the status of S00A in the user<br />
program.<br />
Setting the clock/calendar:<br />
To set the clock/calendar data, the following 2 ways are available. In both cases, the<br />
week data is automatically calculated.<br />
(1) Setting the clock/calendar data on the system information screen of the<br />
programming tool.<br />
(2) Using the Calendar Set instruction (CLND) in the user program.<br />
