Operands:

D: The device for storing the current time read in RTC

Explanations:

1. D will occupy 7 consecutive devices.

2. See the specifications of each model for their range of use.

3. Flags: M1016, M1017, M1076. See remarks for more details.

4. The built-in RTC in EH/EH2/SV/SA/SX/SC series MPU offers 7 data (year, week, month, day, hour, minute,

second) stored in D1319 ~ D1313. TRD instruction is for program designers to read the current data in RTC

and store the data to the 7 registers designated.

5. D1319 only reads the 2-digit year in A.D. If you wish D1319 to read the 4-digit year, see remarks for more

information.

Program Example:

1. When X0 = On, the instruction will read the current time in RTC to the designated registers D0 ~ D6.

2. The content of D1318: 1 = Monday; 2 = Tuesday … 7 = Sunday.
