S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
The clock data stored in to +6 is written to D8013 to D8019 for the built-in PLC real time clock.
- D8018 (year data) can be converted into the 4-digit mode. (Refer to the program example shown later.)
- 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 to +6 in advance, and then execute
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.
Operand type Description Data type
Specifies the head device number to which the clock data is written.
(Seven devices are occupied.)
