- When TWR (FNC167) instruction is executed, the clock data of the real time clock is immediately changed.
Accordingly, transfer the clock data several minutes ahead to
FNC167 instruction when the accurate time has come.
- When setting the clock data (time) using this instruction, it is not necessary to control the special auxiliary relay
M8015 (time stop and time setting).
- If a numeric value indicating impossible date/time is set, the clock data is not changed.
Set the correct clock data, and then write it.
