C-166 Parameter ReferenceAC30 series Variable Speed DriveReal Time ClockParameters::Device Manager::Real Time ClockParameter Name No. Path Default Range Units WritableTime and Date 1186 Parameters::Device Manager::Real TimeClock1970/01/01 1970/01/01 to 2038/01/19 ALWAYSTime and Date in the format yyyy/mm/dd hh:mm:ssTime Zone Offset 1228 Parameters::Device Manager::Real TimeClock0.00 -14.00 to 14.00 ALWAYSA value in hours that defines the difference between Coordinated Universal Time, (UTC), and local time. UTC is equivalent toGrenwich Mean Time, (GMT). This value is required when the time is to be set from a network source using the SNTP client.DST Active 1225 Parameters::Device Manager::Real TimeClockFALSE ALWAYSWhen TRUE, one hour is added to the internal time before being presented as the value in “Time and Date”.Functional DescriptionIO Option Fitted with Real Time ClockWhen 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 Clockhardware. 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 timewrite 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 timeeven when power to the drive is removed.SNTP ClientWhen the SNTP client is enabled, “Time and Date” is updated from the NTP master, adjusted for Time Zone and DST.SNTP ServerWhen 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 OptionWhen no IO Option is fitted “Time and Date” may be used as the destination of a broadcast time from a communications master.
