Diagnostics messages
● Check time-of-day synchronization
If synchronization is via the mobile wireless network the option cannot be activated.
If this option is enabled, the RTU checks whether its time of day has been set according
to the settings made.
– If the time of day was set, the RTU enters a diagnostics message of the class. "INFO"
– If the time of day could not be set, the RTU enters a diagnostics message of the class.
The diagnostics messages are entered incoming/outgoing; in other words, only the last
message is entered in the diagnostics buffer.
● Reduction factor for communication cycle
By selecting an entry from the drop-down list, you specify the reduction factor for the
cycle in which the RTU checks the time of day synchronization.
The basis for the checking cycle is the basic cycle of the communication mode that you
configure on the WBM page "Operating mode".
If you select a reduction factor of 1, the acceptance of the time of day is checked with
each change to the communication mode.
If you select a higher reduction factor, the cycle is increased according to the displayed
value.
Set system time manually
Select one of these options if you want or need to reduce communication via mobile
wireless.
The system time set here is kept by the internal clock of the RTU. For information on the
accuracy, see section Technical data (Page 261).
● New system time
Here, enter the current time of day manually.
When making your entry, keep to the specified format.
Month, day, and hour can also be entered as single digits. Example: March is accepted
as "03" or as "3".
If you click the Apply new time of day button the RTU adopts the entered time of day.
● Adopt PC time
If you click the Adopt PC time button the RTU adopts the time of day from the
configuration PC.
