Explanations:
1. TWR instruction updates the RTC with the value set in S.
2. If the time data in S exceeds the valid calendar range, it will result in an “operation error”. PLC
will writes in the smallest valid value automatically, M1067 = ON, M1068 = ON, and error code
0E1A (HEX) is recorded in D1067
3. For explanations of associated flags and the characteristics of RTCS, please refer to Points to
note of TRD instruction.
Program Example 1:
When X0 = ON, write the new time into RTC.

RTC
Program Example 2:
1. Set the current time in RTC as 2004/12/15, Tuesday, 15:27:30.
2. The content of D0~D6 is the set value for adjusting RTC.
3. When X0 = ON, update the time of RTC with the set value.
4. When X1 = ON, perform ±30 seconds correction. Correction takes place when M1017 goes
from OFF to ON (Second data in 0 ~ 29: reset to 0. Second data in 30 ~ 59: minute data pluses
