2 Introduction
The devices ibaPADU-8, ibaPADU-16, ibaPADU-32 and ibaPADU-32-R (Parallel Ana-
log Digital Units) are designed for data acquisition and control purposes for up to 1 kHz
sampling rate. The four basic device types differ only in the amount of signals per de-
vice i.e. ibaPADU-8 = 8 analog plus 8 binary inputs. Concerning resolution and accu-
racy all devices are similar.
To meet a variety of demands the devices differ in the number of channels and hous-
ings:
ibaPADU-8: Standalone device with 8 A+8 D channels and DIN-rail mount
ibaPADU-16: Table chassis with 16 A+16 D channels and AC 115 V/250 V power
supply
ibaPADU-32: Similar to ibaPADU-16 but with 32 A+32 D channels
ibaPADU-32-R: 19“ rack mount device with 32 A+32 D channels and
AC 115 V/250 V power supply
If no special reference to a device is made in the following text the devices are named
as ibaPADU in general. For special measuring tasks devices with different I/O physics
(i. e. ±20 mA) or higher input impedance (ibaPADU-8-HI) are available
(see chapter 8.3).
The devices are ideally suited for the following applications:
Process data acquisition
Commissioning
Trouble Shooting and error detection
Portable measuring devices (e. g. with the table versions)
To guarantee a good dynamic range or SNR ratio of the signals every A/D channel is
equipped with its own A/D converter.
All ibaPADU devices can be linked in a daisy-chain on the fiber optic links. A maximum
of 64 analog plus 64 digital channels may be connected per link (i. e. 2 x ibaPADU-32,
8 x ibaPADU-8).
For examples for different topologies see chapter 7.2.

6 Mounting and Dismounting
6.1 ibaPADU-8
6.1.1 Mounting
Locate the DIN-rail mounting clip on the rear side of the device. Place the device on the
DIN rail so that the top part the mounting clip engages the top part of the rail appropri-
ately. Slowly push down and in so that the bottom part of the mounting clips snaps onto
the bottom edge of the rail and firmly fixes the device to the DIN-rail.
Then connect power supply (correct polarity!), the analog and/or digital signal connec-
tions and the fiber optic cable(s). Shield if required.
6.1.2 Dismounting
Disconnect all external connections from the device.
Grasp the device with one hand firmly on the top side. With your free hand, grasp the
bottom of the device so that your index and middle fingers rest on the grounding screw.
Lightly push down with the hand on the top side of the device and simultaneously pull
forward with your other hand. With this action, the device should free itself from the
DIN-rail.
6.2 ibaPADU-32-R
6.2.1 Mounting
Fix the device with the four front panel screws into the cubicle. In case of high me-
chanical duty (acceleration > 1 g) support the device at the rear end or mount it on
rails.
Once fixed, on the rear side connect the power supply cord and switch on the device.
Connect fiber optic cable(s) to the TX/RX ports and set device mode and address with
the dial switches.
If the rear side of the device is not accessible after mounting, e. g. in case of closed
cubicle, back to the wall without a swing rack, take above mentioned actions vice ver-
sa. First connect the rear-side cables, dial mode and address and switch on the power
switch. Then move the device carefully into the cubicle (FO-cables, watch limited cable
bending!) and fix the four front panel screws.
6.2.2 Dismounting
Disconnect all external connections from the device. Unscrew the four front panel
screws (and the additional rear holding if present) while holding the device securely.
Remove device from cubicle.
If the rear side of the device is not accessible when inside the cubicle, act vice versa.

7 System topologies and addressing
All ibaPADU devices are normally connected in a straight line topology to their respec-
tive ibaFOB-cards. In case of using the external synchronization function (ibaPADU-8
only) the devices are linked in a ring topology. The outputs of the devices are to be
connected with the input of the following devices until all devices are interconnected
and the last device is connected to the ibaFOB-card. All addresses (1...8) within a
chain must be unique.
7.1 Addressing
One address represents 8 analog +8 digital channels. Therefore devices which hold
16 A+16 D channels need two addresses, an ibaPADU-32 needs four addresses re-
spectively.
Hence, you may connect chains of:
8 ibaPADU-8 or
4 ibaPADU-16 or
2 ibaPADU-32
with 1 fiber optic link.
It is permitted to combine different ibaPADU devices in one chain.
Note
Cascading ibaPADU-16, ibaPADU-32 or ibaPADU-32-R is allowed with serial num-
bers 1000 or higher of these devices (3Mbit telegram).
ibaPADU-16, ibaPADU-32 and ibaPADU-32-R devices with serial numbers 1000 or
higher cannot be connected to ibaCom-PCMCIA or ibaFOB x/4 cards (ISA). ibaPADU
devices with S/N <1000 cannot be operated with ibaFOB-io-X cards because these
cards do not support the 2Mbit protocol.
In ibaPDA the card type ibaFOB is not allowed for ibaPADU-16, ibaPADU-32 and
ibaPADU-32-R devices with serial numbers 1000 or higher.

7.2 Examples for topologies
Example 1: Homogeneous ibaPADU-8 chain
Up to 8 devices in a line
structure.
Every device with 8 analog +
8 digital channels must be set
to a unique station address
between 1...8.
If 2 devices carry the same
address the subsequent de-
vice in the fiber optic link
overwrites the content of the
previous device.
The image, left, shows the
principle of the data pack-
ages in an ibaFOB-telegram.
Each box contains 8 analog +
8 digital signals. The device
address determines where
the data are placed in the te-
legram. Therefore, the posi-
tion of a device in the chain is
independent of the address
setting.
Figure 1: Homogenous ibaPADU-8 chain
Example 2: ibaPADU-32 chain
#1 (occupies 1,2,3 and 4) #5 (occupies 5,6,7 and 8)
2 devices in a line structure.
The device addresses are to
be set as follows.
Because every device needs
four addresses the settings
#1 and #5 are correct only in
order to use all signals of
both devices!

Example 3: Mixed chain with ibaPADU-16 and ibaPADU-32
#1 (occupies 1 and 2) #3 (occupies 3,4,5,6) or
#4 (4,5,6,7) or
#5 (5,6,7,8)
2 devices in a line structure.
Device settings are to be set
as follows:
For example: addresses #1 and #4
ibaPADU-16: Addr. #1; also
the addresses #2 or 3 would
be allowed for Padu16.
In the last case the ibaPADU-
32 must be set to #5 in order
to use all of its signals without
overwriting the data from
ibaPADU-16
Figure 3: Mixed chain with ibaPADU-16 and ibaPADU-32
Example 4: Connection to Notebooks via ibaCom-PCMCIA-F card
#4 (occupies 4 and 5) #1 (occupies 1,2,3 and4)
2 devices in a line structure
connected to a notebook
computer via ibaCom-
PCMCIA-F card.
The last device in the chain
is connected to the
ibaCom-PCMCIA-F card via
the RJ11 cable.
Use the fiber optic adapter
ibaCom-FO-A to do the same
via fiber optics (connected to
TX)
Figure 4: Connection to Notebooks via ibaCom-PCMCIA-F card

8.2.1.2 Fiber optic input X11 (RX) and output X10 (TX)
The 2 connectors (ST type) serve to connect the device to the fiber optic bus.
The X10 output has all data of the device itself and – in case of a daisy chain – the data
from all previous devices. Chaining is done when X10 of a device is connected to X11
of the next device. The last output must then be connected to a fiber optic input of the
ibaFOB-card (or ibaLink-SM-card if used as I/O expander). Connecting and disconnect-
ing of devices on the fiber optic links is allowed at all times. Interrupting the fiber optic
link leads to missing data for the time period of the interruption.
8.2.1.3 Device address setting with Addr.-switch (S1)
S1 is used to set the device address (1 … 8). Each address represents 8 A + 8 D chan-
nels.
Important note
The position of the address switch S1 must not be “0”, since otherwise the link is
broken.
8.2.1.4 Device Mode setting with mode-switch (S0)
S0 sets the device mode. Mode = 0 = Run (standard); other modes are not supported.

8.2.2.2 Fiber optic Input X11 (RX) and output X10 (TX)
The 2 connectors (ST type) serve to connect the device to the fiber optic bus.
The X10 output has all data of the device itself and – in case of a daisy chain – the data
from all previous devices. Chaining is done when X10 of a device is connected to X11
of the next device. The last output must then be connected to a fiber optic input of the
ibaFOB-card (or ibaLink-SM-card if used as I/O expander). Connecting and disconnect-
ing of devices on the fiber optic links is allowed at all times. Interrupting the fiber optic
link leads to missing data for the time period of the interruption.
In order to use all signals of an ibaPADU-16 up to four devices can be operated in a
chain on one FO-link, when using ibaPADU-32 up to 2 devices.
8.2.2.3 Device mode setting with mode-switch (S0)

8.2.2.4 Device address setting with Addr.-switch (S1)
S1 is used to set the device to its address (1...8). Each address represents 8 A + 8 D
channels. An ibaPADU-16 always needs (occupies) two addresses, an ibaPADU-32
four addresses. Odd addresses are allowed, e. g., if the line begins with a single
ibaPADU-8 followed by an ibaPADU-16.
Subsequent devices will overwrite data from previous devices if the same address ex-
ists multiple times in a chain.

8.2.5 Service interface (X12)
A 9-pin SUB-D port, found on the bottom side of the device is dedicated to load new
firmware on the device. For loading new firmware from a PC into the device you'll need
a standard V.24 interface cable.
Note
Please contact iba regarding loading new firmware. You will get the required files and
further information about the loading procedure.
Important note
In normal operation mode the V.24-cable must not be connected.
8.2.6 Shield connector(s) for physical earth
Proper connection of cable shielding to the device should be ensured. The shield con-
nector can be found on the bottom side of the device (or on the right side of each con-
nector on ibaPADU-16/-32/-32-R). It should be connected with any total shield that
serves for all cables. In addition, each individual sensor channel shield must be con-
nected to its respective input channel shield pin.
Note
Connect shield on one cable side only to avoid ground loops.
Note
Always ground the DIN rail on which the device is installed.
