Resolution of the displayed values
In the display, set values can be adjusted in fixed increments. The number of decimal places depends on the device model.
The values have 4 or 5 digits. Actual and set values always have the same number of digits.
Adjustment resolution and number of digits of set values in the display:

USB port (front side)
The frontal USB port, located above of the rotary knobs, is intended for the connection of standard USB sticks and can be
used for loading or saving sequences for the arbitrary and the XY generator, as well as for recording measured data during
running operation.
USB 2.0 and 3.0 sticks are well supported. The stick must be
FAT32
formatted.
All supported files must be held in a desig
-
nated folder in the root path of the USB stick in order to be found. This folder must be named
HMI_FILES
, such that a PC
would recognize the path G:\HMI_FILES if the drive were to be assigned the letter G. Subfolders are supported. In case there
are multiple files of the same type, e. g. such starting with “wave”, the device will list the 20 first it can find.
The control panel of the device can read the following file types and names from a stick:
File name
Description
Section
wave_u<arbitrary_text>.csv
wave_i<arbitrary_text>.csv
Function generator for an arbitrary function on voltage (U) or current (I)
The name must begin with
wave_u
/
wave_i
, the rest is user defined.
profile_<arbitrary_text>.csv
Previously saved user profile. A max. of 10 files to select from is shown
when loading a user profile.
mpp_curve_<arbitrary_text>.csv
User-defined curve data (100 voltage values) for mode MPP4 of the
MPPT function
psb_pv<arbitrary_text>.csv
psb_fc<arbitrary_text>.csv
PV or FC table for the XY function generator.
The name must begin with
psb_pv
or
psb_fc
, the rest can be user de-
fined.
pv_day_et_<arbitrary_text>.csv
pv_day_ui_<arbitrary_text>.csv
Day trend data file to load for the simulation modes DAY I/T and DAY U/I
of the extended PV function.
iu<arbitrary_text>.csv
IU table for the XY function generator.
The name must begin with
iu
, the rest can be user defined.
The control panel of the device can save the following file types and names to a USB stick:
File name
Description
Section
usb_log_<nr>.csv
File with log data recorded during normal operation in all modes. The
file layout is identical to the those generated from the Logging feature
in EPS
Power Control. The <nr> field in the file name is automatically
counted up if equally named files already exist in the folder.
profile_<nr>.csv
Saved user profile. The number in the file name is a counter and not
related to the actual user profile number in the HMI. A max. of 10 files to
select from is shown when loading a user profile.
wave_u<nr>.csv
wave_i<nr>.csv
Sequence point data (here: sequences) of either voltage U or current I
from arbitrary function generator
