Overview

A clock (RTC) is built into the Communication Control Unit.
The clock data from this clock is used for timestamps in the event logs and for the time and date of
files that are created on the SD Memory Card.
The following functions are supported.
• Reading/writing the clock from the Sysmac Studio
• Reading the clock from system-defined variables (Writing is not possible.)
• Correcting the clock from an NTP server
Communication Control Unit
Precautions for Correct Use
The clock data is retained by a built-in capacitor in the Communication Control Unit. When the
power of the device is turned OFF if the retention time in the built-in capacitor is exceeded, the
clock data are initialized. If you use the clock data in the event log and other functions, specify
the clock data when you turn ON the power supply every time.
Clock Data Range
• 1970-01-01 to 2069-12-31 (January 1, 1970 to December 31, 2069).
Setting the Time Zone and the Local Time
Before you use the Controller for the first time, set the time zone and local time in the clock data.
You can set the time zone and local time from the Sysmac Studio in the Controller Clock Dialog Box.
