Processing details
• These instructions write the clock data stored in device numbers (s) to (s)+6 to the clock data area (SD210 to SD216 and
SD8013 to SD8019) of the built-in real time clock in the CPU module.
• Executing these instructions immediately changes the real time clock data. Therefore, transfer the clock data of a few
minutes ahead the current time to the clock data area (s) to (s)+6 in advance. Execute the instruction when the actual time
matches the clock data time.
• When using these instructions to set the clock data (i.e., performing time adjustment), control of special relay SM8015
(clock stop/adjustment) is not required.
• If incorrect values (i.e., values out of range) are set to the write source area, the clock data will not be updated. In this case,
correct the clock data in the write source area and execute the instruction.
• Day of the week (SD216 and SD8019) is automatically corrected.
