Downloading Trend and Alarm History
The Copy button on the Trend History and Alarm History
screens can be used to download the data via USB. In order to
download the trend and alarm history:
1. Insert a USB drive into the left side of the HMI panel or
directly into embedded HMI PC.
NOTE: Thirty MB per day should be available on the USB
drive that is inserted for the download of the trend
and alarm history. There is no warning of insufcient
space.
2. If an error message that states “Error mounting the USB
drive” appears on the HMI, remove and re-install the
USB drive. If the problem persists, try a different USB
drive. Name brand USB drives are recommended.
NOTE: Often times, this error message is due to not allowing
sufcient time between inserting the USB drive and
pressing the Copy button (see Step 4 below).
3. After clicking on the "Display Date" button, choose the
desired date.
4. Press the Copy button. This will download the trend and
alarm history for the selected day. (The Unit Control
Processor will store 30 days of history at a maximum.
The Unit Control Processor will automatically delete old
trend history les as needed to make room for new trend
history les. Old alarm history les are not deleted.) The
HMI will display "download complete" once the history
les have been successfully transferred to the USB drive.
5. Repeat this process for each desired day of history. Each
day must be downloaded individually. It is not possible to
download multiple days of history at once.
Viewing/Using Trend History Files:
Trend history les can be recognized by “Trend” at the
beginning of the le name followed by the date. For example,
if there is a le called “Trend20180623.csv,” it indicates that
the le contains trend history from 6/23/2018. If the history is
downloaded for the current day, there will only be trend history
le up to the current hour. No trend history le is created when
the chiller is powered off.
Viewing/Using Alarm History Files:
Alarm history les can be recognized by “AlarmHistory” at the
beginning of the le name followed by the date. For example,
if there is a le called “AlarmHistory20180623.csv,” it indicates
that the le contains alarm history from 6/23/2018. When the
history is downloaded, there will only be one alarm history le
per day. This one alarm history le will contain all of the alarms
from the selected day. If there were no alarms that day, no
alarm history le will appear when the history is downloaded.
All alarm history les are saved from the Unit Control
Processor as .csv les. These les can be opened on a normal
PC and manipulated using a spreadsheet program.
Requesting Tech Support:
If tech support is requested, ALL of the original, unmanipulated
les (Trend.csv and AlarmHistory.csv, ) must be sent together
to Daikin Applied. Any other le formats are NOT accepted.
