System information
- Movement path :
The screen displays the version of the program applied to the MICOM(Master, Slave and Display). "Program version
No." is shown for follow-up service and is useful for trouble shooting in case there is a problem in MICOM.
(1) Year, Month, Day, Day of the week, Hour, Minute and Second
Here, you can set the date and hour. The data will be the reference for information storage time, problem/caution
occurrence time and Scheduled r operation time.
Since it is the reference time for the MICOM operation, please make sure to check whether there is any deviation
from the present time.
(2) Operation data saving cycle
Here, you can set the operation data saving cycle. Operation data are the measured values by the sensors shown
in the basic screen, and saved on every time which was set in the operation data saving cycle when operation the
