Precautions for Correct Use

Precautions for Correct Use
• Do not remove the SD Memory Card (for NX-series) or the SSD (for NY-series) from Drive Bay A
while you are using the Time Series Database Function. Doing so will prevent these devices from
saving TimeSeries data normally.
• Before you perform error determination, make sure that both the Feature Extraction Function and
the Machine Learning Function are running.
• Before the power is interrupted, make sure to change the TSDB service status to Shutdown.
If the power is interrupted without stopping the time series database, it could cause your valuable
equipment data to be lost and cause the time series database to generate an error at the next pow-
er-on.
If an error occurs with the time series database, perform necessary actions as specified in the trou-
bleshooting procedures.
• To prevent a loss of data from the unexpected power interruption or momentary power interruption,
take appropriate measures for the interruption with the uninterruptible power supply (UPS).
• Data is recorded in a ring buffer of the TimeSeries. Data in the TimeSeries may be overwritten ac-
cording to the sampling period and the export period. The storage usage volume of the TimeSeries
can be checked from the AI Operator. Make sure to adjust the export period when you use the Time
Series Database Function.
• When the TimeSeries Record Addition Failed event occurs, replace the TimeSeries storage.
• If you insert a new storage into a wrong drive bay when you replace the storage, the AI Controller
may not start up. Make sure to insert an expansion storage into Drive Bay A.
• Do not replace the main storage inserted into the AI Controller to another main storage of a different
model. If you do so, it could prevent the AI Controller from starting up.
• If you use an OMRON SD Memory Card, the life expiration of the SD Memory Card can be detected
in the following methods.
When the life expiration is detected, replace the SD Memory Card.
a) _Card1Deteriorated (SD Memory Card Life Warning Flag) system-defined variable
b) SD Memory Card Life Exceeded event
