7.6.2 Setting items in Time synchronization setting
When the MES interface module cannot obtain time information from the SNTP server
computer due to failure of the network or time synchronization server, it behaves as
follows:
(a) When time information is not obtained at the time of powering ON the
programmable controller from OFF, or resetting the programmable controller CPU
1) The operation for the case of selecting [Synchronize with programmable
controller CPU time] is performed. (Adjusted to the time of CPU No.1. [Daylight
saving setting] is not enabled.)
2) Error code, 0A06h is output to the error log.
3) One minute later, time query is executed again to the SNTP server computer.
(If the time query is successful, [Daylight saving setting] is enabled.)
(b) When time information is not obtained in timings of once a minute
1) The module continues its operations based on the information that was
successfully obtained by time query.
2) When the previous time query was successful, error code, 0A07h is output to
the error log.
3) One minute later, time query is executed again to the SNTP server computer.
Whether time query to the SNTP server computer is executed successfully or not
can be confirmed by [Online] - [View working log].
