Operand:

S: Set value for RTC (occupies 7 consecutive devices)

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

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
