Precautions
The following shows the considerations for the time synchronization setting in a multiple CPU system.
■Windows setting
To synchronize time in this product (CPU No.2 or later), change the following settings to 'Off' in 'Date & Time' on Windows.
• "Set the time automatically"
• "Set time zone automatically"
*1 The "Time zone" setting in 'Date and Time' on Windows will automatically change to the one on the CPU No.1 module.
■Windows time zone setting
When synchronizing time with a programmable controller system, the 'Date and Time' settings on Windows will be as follows:
• "Time zone": (UTCXXX) MELSEC iQ-R series CPU
• "Adjust the daylight saving time automatically": OFF
The following shows the examples of time zone.
• UTC+9: (UTC+09:00) MELSEC iQ-R series CPU
• UTC-12: (UTC-12:00) MELSEC iQ-R series CPU
*1 XXX: Complies with time zone of the CPU module (CPU No.1)
*2 The "(UTCXXX) MELSEC iQ-R series CPU" is added to the list of "Time zone." If the "Time zone" setting is changed manually while this
product is in use, the time zone which is added to the list at time synchronization will be applied.
*3 If the time zone setting of the CPU module (CPU No.1) is changed, the changed time zone will be applied when synchronizing time. The
time zone which is added before changing the setting will be deleted from the list.
*4 The added time zone cannot be deleted manually. If the time synchronization function is disabled, the time zone which is added at last
will remain on the time zone list.
The setting name of Windows time zone, which is added by this product, is determined depending on the language selected
at the Windows setup.
Language of Windows
Japanese
Other than Japanese
Even if the Windows display language is changed, the setting name of the time zone will not be changed from the language
selected at the Windows setup. Therefore, the following cases may occur:
• The setting name is displayed in Japanese while the Windows display language is other than Japanese.
• The setting name is displayed in English while the Windows display language is Japanese.
To match the setting name with the current Windows display language, perform the following procedure:
1.
Select "Region" in the Control Panel.
The "Region" screen appears.
2.
Select the [Administrative] tab.
3.
Click the [Copy settings] button in "Welcome screen and new user accounts."
The "Welcome screen and new user accounts" screen appears.
4.
Check the status of "Current user," and select the checkbox of "Welcome screen and system accounts" displayed at the
bottom of the screen.
5.
Click the [OK] button.
6.
Restart Windows.
