Functional Description

IO Option Fitted with Real Time Clock

When an IO Option is fitted, (part number 7004-01-00 or 7004-02-00), this parameter 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. Once set the RTC hardware on the IO option will maintain the time even when power to the drive is removed.

No IO Option

When no IO Option is fitted this parameter may be used as the destination of a broadcast time from a communications master.
