overview
This section explains a sample that synchronizes the time between a PC and a PLC. This sample gets the time from the PC and writes it to PLC.
The Time sync action is a function that writes PC time information to PLC (tag). Information from the year to the second is written to separate tags, and the ladder on the PLC side processes the written date information into a time that matches the PLC format, synchronizing the time.
Action used: Time sync action

Action Settings
1.Time syncRegister action "A01".
2.From the Shutdown tab, configure the screenshot settings.
•Synchronization method: Set the computer's time to the PLC (tag)
•Check year "U01.F01.YEAR"
•Check the month "U01.F01.MONTH"
•Check the day "U01.F01.DAY"
•Check "U01.F01.HOUR"
•Check the minute "U01.F01.MINUTE"
•Check the second "U01.F01.SECOND"
Event Settings
1.Create a Tag event to perform the action.
In this example, we will set the event to occur when U01.F01.T01 becomes TRUE.
Set the execution action to "A01".
Application of this sample
This sample introduced an example of a process for writing the PC time to a PLC, but by selecting "Set the PLC( tag) time to the PC" in the synchronization method settings, you can change the PC time based on the PLC date and time data.
