2 Introduction
The ibaPADU-C-8AI is intended for off-line data recording of process data. With the in-
ternal lithium ion battery the device can be powered for about 19 - 24 h independent of
the main power. Once the ibaPADU-C-8AI is connected to the mains power grid, the
internal battery will be charged automatically, and thereby provides by-pass protection
during unexpected power failure.
The device is characterized by its simple handling. It is configured via an editable text
file that is saved on the device in the "config" directory.
The sampling time can be adjusted for long-term measurements (sampling rate 1 sam-
ple/min) and measurements with high sampling rates (1000 samples/s).
The measurement data recording is started and stopped by:
keystroke (manual) or
external signal (triggered)
To read the measurement data, the device is connected to a PC via an USB connection.
The PC recognizes the devices per plug and play like a mass storage device. In addition,
it is possible to retrieve the data using the network connectivity via FTP.
The ibaAnalyzer

5.4 Interfaces
5.4.1 DC input X14
An external power supply (9-30 V, DC) can be connected via the DC input and the inter-
nal battery can thus be charged.
The device switches to battery operation if there is no external power supply available.
Polarity X14:
5.4.2 Ethernet interface X22
Connectivity to a network to retrieve the data via FTP.
Note
This is only possible if the device is not connected as a mass storage via USB and an
IP address has been configured.
5.4.3 USB interface X23
A PC can be connected via this USB interface in order to read data. At the same time
the internal battery is charged.
Important note
When a PC is connected to the device via USB while measuring, the measuring accuracy
< 0.1% of the total measuring range could be exceeded due to ground loops. Therefore
we recommend disconnecting the USB connection from the PC while measuring.
Power should be supplied via the DC input or the internal battery. The access to the data
via Ethernet has no effect on the measuring accuracy.

6 Commissioning and configuration
The configuration is done via a text file (config.ini), which is stored in the memory of the
device in the directory "config". The file can be accessed and adjustments can be made
by a PC connected via the USB or the Ethernet. Subsequently the file is stored in the
device memory.
Note
During the initial start-up the PC can only be connected via the USB. Only once the
device IP address has been changed according to its network environment, you will
have access to the device via the Ethernet.
The following parameter can be set:
sampling rate
trigger
time zone (hours and minutes)
data format (dat or csv)
DHCP
device IP address
subnet mask
gateway IP address (for time synchronization)
signal name
scaling
unit name
time until an automatic shut-down
6.1 Requirements

Note
The function “automatic shut-down” is a protection against battery discharging. When the
device is not active it will be shut down automatically after the time set here. The device
will not be shut down, when data capturing is active or when an external power supply is
applied via USB or DC.
The function is switched off, when the time is set to zero.
sampleRate_ms:
sampling rate in ms
fileType:
possible configuration "dat" or "csv"
trigger:
possible configuration "none" or "highPulse"
autoCleanup:
on: At least 100 MB of hard disk memory space remain free by
deleting the oldest measuring files. The recording of measuring
data continues.
off: If free memory space on the internal hard disk is below
40 MB, the recording of measurement data will be automatically
cancelled.
Default setting: „off“.
Note
Only files with the following format are deleted by the “auto cleanup” function:
paduc_2014-12-31_23.59.59.dat
Only empty directories with the following format are deleted: 2014-12-31
name:
Names can be assigned to the 8 analog and 8 digital input sig-
nals. These names will be visualized for example in the applica-
tion ibaAnalyzer. The name may have up to 63 characters. The
default name for analog signals is „Voltage[0]“ to „Voltage[7]“,
for the digital signals „Digital[0]“ to „Digital[7]“.
unit:
Unit of the value to be measured
The maximum length of the name is 7 characters
Example: W (power given in Watt)
max:
Maximum value, used for scaling2
Example: 10 V input voltage = 100 W
min:
Minimum value, used for scaling
Example: -10 V input voltage = -100 W
It is also possible to scale the signals asymmetrically:
Example: 10 V input voltage = 250 A
-10 V inputs voltage = -100 A
6. Save the configuration file again under "config.ini" in the "config" directory.
2
The scaling factors can be entered according to scientific notation, i.e. 103complies with 1 E3. If invalid
values are entered (letters except E or special characters), scaling will be ignored.

7. Close the explorer and remove the device symbol from the system bar with "Securely
remove hardware".
8. Briefly press theS11 key or start the device anewto accept thechanged configuration
file.
Note
Should the time synchronization be done via the gateway, then the device must have
access to the Internet.
The file system can be destroyed and the risk of data loss is present when the mass
storage is improperly removed.
Tip
Files in csv format are uncompressed and therefore occupy more storage space. It is
therefore recommended to use files in dat format.
Tip
During a faulty configuration an error log is stored in the "log" directory, which indicates
the current error in clear text.
6.2.1 Time synchronization
The time can be synchronized via an external server. The timeserver address is stored
in the device (default time server is FU Berlin):
URL: time.fu-berlin.de
IP: 130.133.1.10
Protocol: Time Protocol
If a NTP timeserver is available in the network, it can be used for time synchronization.
For this purpose, enter the IP address of the NTP timeserver in the config.ini file.
If you want to use an external timeserver via the Internet, enter the IP address of this
timeserver in the config.ini file. To have access to the timeserver when it has a fixed IP
address, the gateway address for the Internet access must be set in the “config.ini” file:
Example: gatewayIpAddress = 192.168.0.1
The time will be synchronized every time when the device boots up and when data cap-
turing starts.

Manual
ibaPADU-C-8AI
18
Issue 1.11
Note
If the timeserver is not available, measurement will be started without synchronization.
6.2.2 Product information
The file “product.log” is stored on the device in the “log” directory. It contains important
device information, such as hostname, serial number, hardware and firmware versions,
MAC address etc.

6.3 Start measurement process
First connect the input signals with the analog or digital inputs. The measurement can
be started in two ways:
6.3.1 Start measurement process manually
The manual measurement process is started and stopped by briefly pressing the S11
key. Proceed as follows:
1. Switch the device on by briefly pressing the S11 key. All LEDs initially light up in red,
once the device is ready L1 lights up orange.
2. Start the measurement by briefly pressing the S11 key. As long as the measurement
process is running, the L1 will flash in green.
3. You can stop the measurement by briefly pressing the S11 key again. L1 lights up
orange.
6.3.2 Start measurement process triggered
If the measurement process should be started via a trigger signal, then it must be entered
in the configuration file "config.ini":
Configuration for "trigger": [highPulse]
The measurement process only takes as long as the trigger signal is pending (digital
signal, start trigger increasing flange, stop trigger decreasing flange). The trigger signal
must be pending at least as long as the configured sample rate in order to start the data
recording.
The trigger signal connection is described in chapter 5.4.4 “Analog/digital inputs X1”.
Proceed as follows:
1. Switch the device on by pressing the S11 key for a longer period. All LEDs initially
light up in red, once the device is ready L1 lights up orange.
2. Go to the "wait for trigger" state by briefly pressing the S11 key. L1 lights up green.
3. L1 flashes green when the trigger signal is pending and the measurement starts.
Data is only saved while the trigger signal is pending.
4. Once the trigger signal is no longer pending, the measurement is ended and L1 lights
up green.
5. To leave the "waiting for trigger" state, briefly press S11.
Note
During eachmeasurement anew measurementfile is created. During long-term record-
ings new measurement files are automatically created after every 100,000 samples.
Once the free memory space on the internal memory falls below 40 MB, the measure-
ment data recording is automatically aborted. This is indicated by the LED L1 flashing
red. In addition, an error message file "Error.log" is stored in the "log" directory with the
following content: „[ERROR] stopped measuring --> running out of disk space“.
