2 Introduction
The ibaPADU-8-ICP (parallel analog & digital unit 8 channel ICP) serves as a data ac-
quisition device for applications requiring sample rates to 25 kHz per channel. This de-
vice is suitable for vibration measurement applications, such as …
machine vibration monitoring
rolling element bearing monitoring
rolling mill chatter monitoring
various dynamic process monitoring
Since the majority of applications require measurements from ibaPADU-8-ICP devices
on a scheduled, periodic basis, devices are multiplexed. Each of up to 4 fiber-optic
links (on a iba FOB 4i PCI-card) may interface with individually addressed ibaPADU-8-
ICP units. Depending on the processing power of the PC, either 8, 16, 24 or 32 ICP
and binary channels may be sampled simultaneously.
Per fiber-optic link, a maximum of 96 devices can be addressed via a ibaFOB-4i/-4o
combination or a ibaFOB-io card interface. This provides a maximum of 4x96x8 = 3072
analog and digital measurement channels. Each analog channel can be connected di-
rectly to ICP®type sensors without interposing signal conditioning. ICP®sensors must
meet the specification of IMI1, whereby each channel is powered with a current loop.
This provides both a signal level for measurement as well as open-circuit, short-circuit
detection possibility.
Another possible application is the simultaneous monitoring of up to 128 analog and
128 binary channels with up to 25 ks/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 accuracy of
max 100 ns (plus fiber optic cable length = approx. 4 ns /m) difference without any jit-
tering. 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 ICP®channel comprises a programma-
ble analog gain, programmable low-pass filter, and a 14-bit ADC.

with other ibaPADU-8-ICP devices and the ibaFOB-card links. Connect the TX port of
the iba FOB-card to the RX port of the first ibaPADU-8-ICP device in the ring. Then,
connect the TX port of this ibaPADU-8-ICP device to the RX port of the next ibaPADU-
8-ICP device in the ring. Continue until all of up to 96 ibaPADU-8-ICP devices are inter-
connected. Finally, connect the TX port of the final ibaPADU-8-ICP device to the corre-
sponding RX port of the ibaFOB-card.
7.2.3 Setting the Device Address with S1 and S2 Decade Switches

7.2.7 Service Interface
Note
Firmware may only be updated by iba!
A 9-pin SUB-D port, found on the under side of the device, may be used to load new
firmware for the device. New firmware is loaded via a V.24 interface. Please contact iba
regarding loading new firmware.
The firmware will be loaded via the pins 2, 3, 5 and the bootpin (7). At first, the device
must be set into boot mode by applying 0 V to the bootpin and then the device must be
booted (switch off and on the power supply). Now the device is in boot mode and ac-
cepts the new firmware. Afterwards the V.24 cable has to be removed (or apply 5 V to
the bootpin) and the device has to be rebooted. The device is now booting with the new
firmware.
Under normal service conditions, the V.24 cable must not be connected.
Service Interface Pinout Diagram
7.2.8 Shield Connector for Physical Earth
Proper connection of cable shielding to the device should be ensured. The shield con-
nector found on the underside of the device should be connected with any total shield
that serves for all sensor cables. In addition, each individual sensor channel shield
must be connected to its respective input channel shield pin.
Note
Sensor cable shield should be connected only on the ibaPADU-8-ICP side in order to
avoid ground loops with the sensor housing.
Note
Always ground the DIN rail on which the device is installed.

8 System integration
As far as no special relation to a PC board is necessary the ibaFOB-S-, -D- or -Dexp-
cards are referred to as ibaFOB card.
ibaPADU-8-ICP devices are interconnected in a ring structure with the ibaFOB serving
as a central controller for all connected devices. Each link on the ibaFOB card has a
TX/RX port for transmission of control signals and reception of data from connected
ibaPADU-8-ICP devices. All devices connected in each fiber-optic link must have
unique addresses.
Figure 1. Ring topology
The TX port on an individual iba-
FOB interface must be con-
nected to the RX port on the first
ibaPADU-8-ICP in the fiber-optic
ring. Installed devices may be in-
terconnected in any order (con-
secutive addresses are not re-
quired) provided that all devices
have unique address settings
(0…95). The TX port on the last
device in the chain must be con-
nected to the RX port on the re-
spective ibaFOB interface card.
Important note
This ring topology is only supported by ibaLogic-V3, since numbering of the devices
can be done automatically in ibaLogic-V3.
The ring topology can also be used in ibaPDA or ibaScope, but the automatic number-
ing is not possible. The user has to change the device number and to restart the acqui-
sition. Therefore this topology is not advisable for continuous measuring.

ibaPADU-8-ICP Manual
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-ICP can be simultaneously sampled at up to 25 kHz.
Each ibaFOB link can support a single ibaPADU-8-ICP. Maximum 32 (analog ICP®and
binary) channels can be sampled continuously using this topology. For continuous
process monitoring, multiplex operation of the device network is not required.
Figure 2. Star Topology
If an ibaPADU-8-ICP is connected
with a fiber optic link of an ibaFOB
card, no other PADU 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 dif-
ferent modes.
It is possible to couple other pro-
cess signals using other input de-
vices available from iba, in which
case the corresponding interface
must be available.
For example, ibaPADU-8 devices
can be used to monitor the pro-
cess state and indicate that high-
speed, ibaPADU-8-ICP monitoring
is required.

8.2 Online Machine Condition Monitoring Topology
Figure 3 depicts a possible topology for online machine condition monitoring. In this
configuration, up to 4x96 ibaPADU-8-ICP can be sampled in a multiplex fashion to pro-
vide up to 3136 online channels per monitoring station. Each ibaFOB link can support
up to 96 ibaPADU-8-ICP, measuring one at a time.
Figure 3 System Topology for Online Machine Condition
Monitoring
Even in the branch with multi-
plexed ibaPADU-8-ICP devices
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-ICP is con-
nected with a fiber optic link of an
ibaFOB card, no other PADU
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.
Note
The use of the ibaBM-FOX-i-3o splitter in conjunction with ibaPADU-8-ICP is not sup-
ported.
Due to the bidirectional data transfer between ibaPADU-8-ICP and ibaFOB-card it is
not possible to split the signals.
If a multiplication of signals is required, please contact iba.

ibaPADU-8-ICP Manual
9 Programmable Settings of the Device
Each ibaPADU-8-ICP is programmable. A single, common sampling rate for all chan-
nels may be set. Each ICP®input channel has a programmable gain and filter setting
as well.
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.
9.2 Input Gain
The following table displays the possible gain settings for an ICP®input channel. Notice
that for small gain values, incremental steps of 0.5 dB are possible. After about 40 dB,
the steps are larger from 1 dB to 6 dB at the end of the scale. Because the device may
not reach a gain that is requested via an ibaFOB telegram, the device returns the ac-
tual gain setting when measurements begin.
Table 1. Possible Input Gains
0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 0.5 dB step area
5.0 5.5 6.0 6.6 6.9 7.5 8.0 8.4 9.1 9.6
9.9 10.5 11.1 11.4 12.0 12.4 13.2 13.6 14.0 14.4
14.9 15.4 15.9 16.5 17.1 17.7 18.4 19.2 20.0 20.5
21.0 21.5 22.0 22.5 23.0 23.5 24.0 24.5 25.0 25.5
26.0 26.6 26.9 27.5 28.0 28.4 29.1 29.6 29.9 30.5
31.1 31.4 32.0 32.4 33.2 33.6 34.0 34.4 34.9 35.4
35.9 36.5 37.1 37.7 38.4 39.2 40.0 40.9 41.9 43.1 1-1.5 dB step area
44.4 46.0 48.0 50.5 54.0 60.0 bigger steps
Tip
Typical ICP®circuits have a settling time of 3-4 seconds after gain changes. This is
also true when the sensor saturates the circuit.
Note
With an input gain of 40 dB and higher, the signal/noise ratio quickly deteriorates. This
can be an indication that a more sensitive sensor is required, e.g. 1000 mV/g instead of
100 mV/g.

9.3 Low-Pass Filter
A programmable 72 dB 6-pole low-pass filter is implemented on each ICP®channel.
Commands sent from the ibaFOB are used to set this filter frequency.
The frequency range for the low-pass filter is 0.5 Hz …25 kHz.
Specification Example
Range (Hz) Accuracy Reference (Hz) Actual Value (Hz)
100-250 1 % 126 126,3
250-500 1 % 270 270,3
500-1000 1 % 990 990,1
1000-10000 10 % 3750 3773,6
10000-25000 10 % 21500 22222
Tip
The programmable digital filter produces modulation component frequencies with
< 72 dB of the maximum signal strength. Therefore, the analysis software should take
this into account.
Tip
At corner frequencies < 1000 Hz, reflected frequencies above 50x the corner fre-
quency are possible.
Example 1: fc= 100 Hz
reflected frequency band starts at 50 x 100 = 5000 Hz. A signal frequency of 5100 Hz
would be noticeable at 100 Hz.
Example 2: fc= 1000 Hz
reflected frequency band starts at 50x 1000 = 50000 Hz. A signal frequency of
51000 Hz would be dampened 6 dB 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.
