2 Introduction
The ibaPADU-8-M (parallel analog & digital unit 8 multiplexed) serves as a data acqui-
sition device for applications requiring sample rates up to 25 kHz per channel. This de-
vice is suitable for vibration measurement applications, such as …
drive controller optimization
power line monitoring (with signal conditioning device)
machine vibration monitoring
rolling mill chatter monitoring
various dynamic process monitoring requiring fast signal processing
Since the majority of applications require measurements from ibaPADU-8-M devices on
a scheduled, periodic basis, devices are multiplexed. Each of up to 4 fiber-optic links
(on an ibaFOB-4i -card) may interface with individually addressed ibaPADU-8-M units.
Depending on the processing power of the PC, either 8, 16, 24 or 32 analog and binary
channels may be sampled simultaneously.
Per fiber-optic link, a maximum of 96 devices can be addressed via an ibaFOB-4i + 4o
combination or an ibaFOB-io card interface. This provides a maximum of 4x96x8 =
3072 analog and digital measurement channels.
Another possible application is the simultaneous monitoring of up to 128 analog and
128 binary channels with up to 25,000 samples / s. This operational mode is supported
by PCI cards in combination with the iba Online Data Acquisition software ibaScope
only! The master ibaFOB in that case controls the ADC converter triggering with an ac-
curacy of max. 100 ns (plus fiber optic cable length = approx. 4 ns /m) difference with-
out any jittering. This allows a variety of new applications to be performed in a wide
area with a big amount of simultaneous signals.
In order to provide a rich dynamic range each analog channel comprises a 14-bit ADC.

8 System integration
As far as no special relation to a PC board is necessary the ibaFOB-4i / -4o and/or iba-
FOB-io are referred to as ibaFOB card. It is assumed that the card(s) run in iba FOB-M
mode (controlled by software application)
ibaPADU-8-M devices are interconnected in a ring structure with the ibaFOB serving as
a central controller for all connected devices. An ibaFOB card can control one (ibaFOB-
io) or 4 fiber-optic links (ibaFOB-4i / -4o). Each link on the ibaFOB card has a TX/RX
port for transmission of control signals and reception of data from connected ibaPADU-
8-M devices. All devices connected in each fiber-optic link must have unique ad-
dresses.
The TX port on an individual
ibaFOB interface must be
connected to the RX port on
the first ibaPADU-8-M in the
fiber-optic ring. Installed de-
vices may be interconnected
in any order (consecutive
addresses are not required)
provided that all devices
have unique address set-
tings. The TX port on the
last device in the chain must
be connected to the RX port
on the respective ibaFOB in-
terface card.
Ring topology
Device addresses are set using the address switch settings on the front panel of the
device. See chapter 7.2 “Device view, interfaces and operating elements” for further
details.
Each device in a chain must have its unique address (0…95).
Important note
This ring topology is only supported by ibaLogic-V3, since numbering of the devices
can be done automatically in ibaLogic-V3.

8.1 Process Monitoring Topology Example
Figure 2 depicts a possible topology for process monitoring of mill chatter. In this con-
figuration, up to 4 ibaPADU-8-M can be simultaneously sampled at up to 25 kHz. Each
ibaFOB link can support a single ibaPADU-8-M. Maximum 32 (analog and binary)
channels can be sampled continuously using this topology. For continuous process
monitoring, multiplex operation of the device network is not required.
If an ibaPADU-8-M is connected
with a fiber optic link of an iba-
FOB card, no other ibaPADU
type can be connected to the
same link. But it is allowed to use
other devices on the other links
since the fiber optic links on one
card can work in different modes.
It is possible to couple other
process signals using other input
devices available from iba, in
which case the corresponding in-
terface must be available.
For example, ibaPADU-8 devices
can be used to monitor the proc-
ess state and indicate that high-
speed, ibaPADU-8-M monitoring
is required.
Star Topology

ibaPADU-8-M Manual
Issue 1.9 17
8.2 Online Machine Condition Monitoring Topology
System topology 3 depicts a possible topology for online machine condition monitoring.
In this configuration, up to 4x96 ibaPADU-8-M can be sampled in a multiplex fashion to
provide up to 3136 online channels per monitoring station. Each ibaFOB link can sup-
port up to 96 ibaPADU-8-M, measuring one at a time.
Even in the branch with multi-
plexed ibaPADU-8-M de-
vices only one device can be
used at a time.
The selection of the devices
which signals shall be captured
can be automatically done in iba-
Logic or manually in ibaScope or
ibaPDA.
If an ibaPADU-8-M is connected
with a fiber optic link of an iba-
FOB card, no other ibaPADU
type can be connected to the
same link. But it is allowed to use
other devices on the other links
since the fiber optic links on one
card can work in different modes.
For example, ibaPADU-8 devices
can be used to monitor additional
process variables.
System Topology 3
Note
The use of the ibaBM-FOX-i-3o splitter in conjunction with ibaPADU-8-M is not sup-
ported.
Due to the bidirectional data transfer between ibaPADU-8-M and ibaFOB-card it is not
possible to split the signals.
If a multiplication of signals is required, please contact iba.

Manual ibaPADU-8-M

9 Settings of the Device
Each ibaPADU-8-M is programmable. A single, common sampling rate for all channels
may be set.
9.1 Sampling Rate
The sampling rate can be programmed via the ibaFOB interface in steps of 50 nano-
seconds from 40 s (25 kHz) to 2 ms (500 Hz). The chosen sample rate is then com-
mon for all channels, analog and digital. Each channel has an individual ADC circuit to
ensure very accurate phase matching between channels.
9.2 Input Gain
Note
No input gain may be changed with program setting. The gain factor is fixed to 1. The
response on a parameter request is 0 = 0 dB!
9.3 Low Pass Filter
Note
The ibaPADU-8-M only has a fixed input low pass filter for each channel. No program-
mable setting are to be made for this. The response on a parameter request is
ftp = 0 Hz (no filter).
9.4 Input Impedance
The input impedance changes with frequency!
Standard values for 6 dB low pass
RiON = 100 kOhm @100 Hz; 10 kOhm @ 5 kHz
RiOFF = 50 kOhm
Note
At corner frequencies < 1000 Hz, reflected frequencies above 50x the corner frequency
are possible.
Example 1: fc= 100 Hz
reflected frequency band starts at 50 x 100 Hz = 5000 Hz. A signal frequency of
5100 Hz would be noticeable at 100 Hz.
Example 2: fc= 1000 Hz
reflected frequency band starts at 50 x 1000 Hz = 50000 Hz. A signal frequency of
51000 Hz would be dampened 6dB by the static low-pass filter. This signal would be
noticeable for signal strengths above 20 dB.
If a device for low-frequency applications should be required, iba can supply a variant
of this device for sampling at 1 kHz or less, with a static low-pass filter. Please contact
iba for further details.

10 Data Selection for ibaPADU-8-M
ibaPADU-8-M is actually supported by ibaLogic-V3, ibaScope and ibaPDA-V6 software.
The following chapters describe example configurations in ibaLogic and ibaPDA. The
settings in ibaScope correspond to the settings in ibaLogic, although the dialogs are
slightly different. For setup of the device with ibaScope please refer to the ibaScope
manual.
10.1 Working with ibaLogic-V3
With ibaLogic you may analyse 25 kHz signals. By using additional (slow) process
variables you may define monitoring ranges. In order to conceive and analyze the be-
haviour of dynamic processes which are much faster (40 s) than the usual time base
of ibaLogic (1 ms) the data type ARRAY is used by ibaLogic.
In the following you will find a short description of installation and application of the de-
vice.
10.1.1 Typical Configuration
Configuration with Sensors

Manual ibaPADU-8-M
20 Issue 1.9
10.1.2 Hardware Settings
The connection between ibaPADU-8-M and the software application on the PC is the
ibaFOB-io (-S) PCI-board or the combination of ibaFOB-4i + ibaFOB-4o.
Please note to connect the fiber optic links to the corresponding ports on the ibaFOB-4i
and ibaFOB-4o card (same order top-down), e.g. as shown in the figure above.
Modes of Operation FOB-F and FOB-M
In contrary to previous interface cards, the modes of operation are set by software
means. In ibaLogic there are corresponding dialogs.
Basically, there are two operational modes: FOB-F and FOB-M.
FOB-F is the mode of operation for usual data acquisition with the major part of iba de-
vices such as ibaPADU-8, -16, -32, ibaLink-SM-64-io, ibaLink-SM-128V-i-2o,
ibaNet750-BM etc. The fastest sample rate is 1 kHz (1 ms). You may use ibaPDA,
ibaLogic or ibaScope as software application. When using ibaLogic, only an asynchro-
nous mode is possible, i.e. ibaLogic can not be synchronized by ibaPADU-8-M.
The FOB-M mode is used for fast data acquisition with sample rates of up to 25 kHz
(40 s). Running in FOB-M mode, the ibaFOB-card can only work with the devices
ibaPADU-16-M, ibaPADU-8-M M or –ICP. Only ibaLogic or ibaScope can be used for
software application. The operation in a synchronous mode, i.e. with synchronizing
multiple systems, is possible with ibaScope only.
Menu “File - System Setup - FOB-IO / FOB-M”
The checkbox “Used by ibaLogic” must be checked for ibaFOB-card which is con-
nected to the ibaPADU-8-M.
