Clock data is rewritten if a data rewrite flag changes (OFF to ON or ON to OFF). You cannot change the "Seconds" data. It is reset to "0" when the clock data is rewritten.
For example, October 16, 2005 9:57 PM
The current data in the [Clock Data (Preset Value)] address is 0000.
Write the "Month", "Day", and "Time" into the following addresses.
Write 0010 to [Clock Data (Preset Value)] + 1.
Write 0016 to [Clock Data (Preset Value)] + 2.
Write 2157 to [Clock Data (Preset Value)] + 3.
In the [Clock Data (Preset Value)] addresses, turn ON the 15th bit under "Year" (data 8005) and the clock data is rewritten.
The clock data's [Data Type] is set to BCD.
When setting the clock data using the memory link method, use the five addresses 0004 to 0008 to directly store the data, such as year, month, day, hour, and minute, respectively.
Ethernet Multilink Restrictions
On slave display units, you cannot use the [Common Settings] menu's [Clock Update Settings] to automatically get the time. From the [Clock Update Settings] dialog box, select the [Customize] check box and set up the address values to read as time data. You can retrieve the device/PLC data via the master display unit.
If you want to use time functions on the slave display unit right after powering up, design your system so that the function runs after the clock on the slave display unit is updated. The time lag from when the slave display unit is powered up to when its clock is updated depends on the structure of the Ethernet Multilink connection.
