(3) Holding the collected user alarm data
(a) Overview of the power failure backup
Once the user alarm data are stored in the data storage or the SRAM user area as the alarm log file, the
user alarm data are held even when the GOT is powered off.
When the alarm log file is stored in the data storage or the SRAM user area when the GOT is powered on,
the alarm log file is read automatically and the user alarm history before the power-off is restored.
Data storage
The timing with which alarms are saved in the data storage can be set.
(Rise, Fall, Sampling, ON Sampling, or OFF Sampling)
Data can be saved with touch switch inputs.
