Time Sync is used to define rules and/or actions to be used when comparing the device clock with the host clock.
See the General Object Configuration guide for assistance configuring the General tab. |
Default = 120. This field defines the minimum time difference between the device and host that should result in a time synchronization. If this value is set to zero, all time checks will result in time synchronization.
Range Examples
Device Time | Host Time | Range | Result |
---|---|---|---|
9:00:00 AM | 9:02:00 AM | 0 | Host Time Is Sent To Device |
9:00:00 AM | 9:02:00 AM | 120 | Host Time Is Sent To Device |
9:00:00 AM | 9:02:00 AM | 90 | No Changes Sent To Device |
9:00:00 AM | 8:58:00 AM | 0 | Host Time Is Sent To Device |
9:00:00 AM | 8:58:00 AM | 120 | Host Time Is Sent To Device |
9:00:00 AM | 8:58:00 AM | 90 | No Changes Sent To Device |
Default = Not Selected. Automatically Adjust for Daylight Saving Time.
Default = Not Selected. Select to prevent synchronizing if the hour on the device will change, even if within the "Range Seconds" established above.
Default = 0. This field defines an overall maximum time difference between the device and host that should result in time synchronization. If zero (no max) this check is disabled.
Default = Selected. Alarm and Error values are used when this option is selected. When selected and a time synchronization is triggered by the configured options here, these will be values written to the LastTimeSyncResult OPC item and no synchronization will take place.
Default = -100. The value of the alarm as seen in the OPC client and log files.
Default = -200. The value of the error as seen in the OPC client and log files.
