Additional Information
• NTP clock synchronization is normally performed as follows:
•
If the clock deviation is within 128 ms: The clock is synchronized every 0.5 ms.
• If the clock deviation exceeds 128 ms: The clock is synchronized immediately.
• If the NTP operation timing is set for a specified time interval, the timing will not change even
if the time in the CPU Unit is changed during operation.
(For example, if the time interval is set to 60 minutes, the information is updated 60 minutes
after the last time it was updated even if the time in the CPU Unit is changed.)
