5.5.3 Use Daylight Savings Time
Yes or No
This parameter specifies if daylight savings time will be used in the time
computation.
5.5.4 Database Register
-1 or 0 to 3992 as an even value
This parameter specifies if the NTP time computed by the driver is to be placed
into the module’s database. If a value of -1 is specified, the time will not be
placed into the database. If the value is between 0 and 3992, the time will be
placed in the database. The first 4 bytes will represent the seconds since
1/1/1970, and the second 4 bytes will represent the number of microseconds. An
even value should be used for the register value in order for the data to be stored
correctly.
5.6
[IEC-870-5-104]
This section provides information required to configure a server application with
the module. An item of concern is the maximum size of the total database.
Although it is possible to configure a database of considerable size, the
maximum Class 0 request may not exceed 2048 bytes in size.
