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 EA
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
Also see section
. 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
Handling (start/stop)
With setting
Start/stop with DC input ON/OFF
logging will start each time the DC input 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’s 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 input off the logging is stopped and the log file closed.
3.4.10.3
Log file format
Type: text file in european CSV format
Layout:
Legend:
U set / I set / P set / R set
: Set values
U actual / I actual / P actual / R actual
: Actual values
R mode
: Status of resistance mode being activated or not
Output/Input
: Status of the DC output/input
Error
: Device alarms
Device mode
: Actual regulation mode (also see
Time
: Elapsed time since logging start
Important to know:
•
R set and R actual are only recorded if UIR mode is active (refer to section
•
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
3.4.10.4
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 input ON/OFF
”, the logging will also stop on alarms or events with action
“Alarm”, because they switch off the DC input
•
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
