Functional Description
IO Option Fitted with Real Time Clock
When an IO Option is fitted, (part number 7004-01-00 or 7004-02-00), “Time and Date” reports the time from the associated Real Time Clock
hardware. On receiving an IO Option from the factory the time is not set and the value will be fixed at 1970/01/01 00:00:00. To set the correct time
write to parameter 1186, or enable the SNTP client if an NTP master is available. Once set the RTC hardware on the IO option will maintain the time
even when power to the drive is removed.
SNTP Client
When the SNTP client is enabled, “Time and Date” is updated from the NTP master, adjusted for Time Zone and DST.
SNTP Server
When the SNTP server is enabled, the value of “Time and Date” is adjusted for Time Zone and DST then transmitted to any requesting clients.
No IO Option
When no IO Option is fitted “Time and Date” may be used as the destination of a broadcast time from a communications master.
