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 3 to 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 to the right 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 sticks are widely accepted. USB 3.0 sticks work, but not from all manufacturers. The stick must be
FAT32
formatted and should have a
maximum capacity of 32 GB
.
All supported files must be held in a designated folder
in the root path of the USB drive 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.
The control panel of the device can read the following file types and names from a stick:
wave_u<your_text>.csv
wave_i<your_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_<your_text>.csv
Previously saved user profile. A max. of 10 files to select from is shown when
loading a user profile.
iu<your_text>.csv
ui<your_text>.csv
IU or UI table for the XY function generator.
The name must begin with
iu
or
ui
, the rest can be user defined.
pv<your_text>.csv
fc<your_text>.csv
PV or FC table for the XY function generator.
The name must begin
with pv
or
fc
, the rest can be user defined.
pv_day_et_<your_text>.csv
pv_day_ui_<your_text>.csv
Day trend data file to load for the simulation modes DAY I/T and DAY U/I of the
extended PV function. See section
The control panel of the device can save the following file types and names to an USB stick:
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.
pv<nr>.csv
PF function table data, as calculated by the device. Can be loaded again.
fc<nr>.csv
FC function table data, as calculated by the device. Can be loaded again.
wave_u<nr>.csv
wave_i<nr>.csv
Set point data (here: sequences) from arbitrary function generator of either
voltage U or current I
pv_record_<nr>.csv
Data from the data recording option in the extended PV function according to
for details.
