Operands:
S : Device for storing the new time to be written into RTC
Explanations:
1. S will occupy 7 consecutive devices.
2. See the specifications of each model for their range of use.
3. Flags: M1016, M1017, M1076. See remarks of API 166 TRD for more details.
4. To make adjustment on the RTC built in EH/EH2/SV/SA/SX/SC series MPU, use this instruction to write the
correct time into the RTC.
5. When this instruction is executed, the new set time will be written in the RTC built in PLC immediately.
Therefore, please be noted that the new set time has to match the current time then when the instruction is
executed.
6. If S exceeds its range, the program will regard it as an operation error and the instruction will not be executed.
M1067 and M1068 will be On and D1067 will record the error code 0E1A (hex).
Program Example 1:
When X0= On, write the correct current time into the RTC.

Program Example 2:
1. Set the current time in the RTC as 15:27:30, Tuesday, August 19, 2003.
2. D0 ~ D6 indicate the new set time in the RTC.
3. X10 = On for changing the current time in the RTC and make the changed value the new set value.
