PSI 9000 2U Series
3.4.10 Recording to USB stick (logging)
Device data can be recorded to USB stick (2.0 / 3.0 may work, but not all vendors are supported) anytime. For
specifications of the USB stick and the generated log files refer to section „1.9.6.5. USB port (front side)“ .
The logging stores files of CSV format on the stick. The layout of the log data is the same as when logging via PC
with software EPS Power Control. The advantage of USB logging over PC logging is the mobility and that no PC
is required. The logging feature just has to be activated and configured in the MENU.
3.4.10.1 Configuration 1
Also see section 3.4.3.7 . After USB logging has been enabled and the parameters “Logging interval” and “Start/
Stop” have been set, logging can be started anytime from within the MENU or after leaving it, depends on the
selected start/stop mode.
3.4.10.2 Configuration 2
Also see section 3.4.3.1 . There are additional settings for the CSV file itself as generated by the USB logging feea -
tures. You can switch the column separator format between german/european standard (“Default”) or US american
standard (“US”). The other option is used to deactivate the physical unit that is added by default to every values
in the log file. Deactivating this option simplifies the CSV file processing in MS Excel.
3.4.10.3 Handling (start/stop)
With setting “ Start/stop with DC output ON/OFF ” logging will start each time the DC output of the device is
switched on, no matter if manually with the front button “On/Off” or remotely via analog or digital interface. With
setting “ Manual start/stop ” it is different. Logging is then started and stopped only in the MENU, in the logging
configuration page.
Soon after logging has been started, the symbol indicates the ongoing logging action. In case there is an error
while logging, such as USB stick full or removed, it will be indicated by another symbol ( ). After every manual
stop or switching the DC output off the logging is stopped and the log file closed.
3.4.10.4 Log file format
Type: text file in german/european or US american CSV format (depending on the selected setting)
Layout (default german format shown):
Legend:
U set / I set / P set / R set : Set values
U actual / I actual / P actual / R actual : Actual values
Error : device alarms
Time : elapsed time since logging start
Device mode : actual regulation mode (also see
„3.2. Operating modes“
)
Important to know:
• R set and R actual are only recorded if UIR mode is active (refer to section 3.4.5 )
•
Unlike the logging on PC, every log start here creates a new log file with a counter in the file name, starting
generally with 1, but minding existing files
3.4.10.5 Special notes and limitations
• Max. log file size (due to FAT32 formatting): 4 GB
• Max. number of log files in folder HMI_FILES: 1024
• With setting “ Start/stop with DC output ON/OFF ”, the logging will also stop on alarms or events with action
“Alarm”, because they switch off the DC output
• With setting “ Manual start/stop ” the device will continue to log even on occurring alarms, so this mode can be
used to determine the period of temporary alarms like OT or PF
