2 Introduction
The ibaMS8xIEPE module is member of the iba-modular system. The modular concept
of the iba-modular system is designed on the basis of a backplane. You can plug on this
backplane not only the CPU, but also up to 4 input/output modules. The power supply of
the I/O modules is provided by the backplane bus.
The ibaMS8xIEPE module offers 8 analog inputs
In brief:
I/O module for the iba-modular system
8 analog inputs
Galvanically isolated groups of 2 inputs each
Constant current source 4 mA
Typically for IEPE vibration sensors
Detection of broken line and short circuit
Analog and digital anti-aliasing filter
Synchronous sampling
4 channels can be configured as ±24 V voltage input
High-pass 1 Hz or 0.1 Hz can be configured
Sampling rate 1 kHz1… 40 kHz, freely adjustable
24 bit resolution
Rugged design, easy mounting
Certification according to CE
Fields of application
Measurement of mechanical vibration by means of IEPE vibration sensors:
Wind turbines
Condition Monitoring
Test benches
Monitoring of bearings
Mill chatter monitoring
1Due to the integrated filters, a minimum sampling rate of 1 kHz is recommended for the correct operation
of this module, even if an even lower sampling rate (time base) can be set in the ibaPDA configuration.

7.3 Analog inputs
Important note
A channel requires a settling time of about 10 to 50 seconds after switching on. The
settling time in IEPE 1 Hz mode is shorter than in IEPE 0.1 Hz mode.
This also applies, if the signal was overdriven for a short time.
The analog inputs can be adjusted to different operating modes per channel. The oper-
ating mode is configured in ibaPDA.
IEPE input (±5 V) with 1 Hz high-pass filter2
IEPE input (±5 V) with 0.1 Hz high-pass filter
24 V AC input (AI)
24 V DC input (AI)
4 inputs are adjusted permanently to IEPE mode. The mode of the second input of each
root can be configured: IEPE, 24 V AC or 24 V DC. The following table shows the possi-
ble settings:

When set to IEPE mode (default setting) an integrated constant
current source
provides
4
mA (30
V DC) for the connection of IEPE sensors. However, when the inputs are used
as 24 V input, the configuration to 24 V mode has to be done in ibaPDA
before wiring

7.3.3 Error and status signals
The following table shows the error and status signals available in different operating
modes:
IEPE AI-24 V AC AI-24 V DC
Status signal
Data valid 
Error signal
Broken line --
Shorted --
7.3.3.1 Data valid
The “data valid” signal (TRUE) indicates, when the settling process of the corresponding
signal is completed.
If the measured input values are processed before the signal is TRUE, the resulting val-
ues may be falsified.
When an error occurs during IEPE operation (broken line, short circuit), the signal
changes to FALSE.
7.3.3.2 Broken line
The signal indicates both, a broken line and when a IEPE sensor is not connected.
When the sensor supply voltage exceeds 20 V, a broken line will be detected. After a
delay of 10 seconds the error signal “Broken line” changes to TRUE.
When the sensor supply voltage decreases below 20 V again, the error state will be reset
and the signal changes to FALSE with a 10 second delay.
7.3.3.3 Shorted
In case of a short circuit, this error signal changes to TRUE with a delay of 10 seconds.
When the short circuit is eliminated and the sensor is connected properly again, the error
state will be reset automatically and the signal changes to FALSE with a 10 second delay.

8 Start-up / Update
Important note
I
nstalling an update can take some minutes.
Please do not switch off the device when an
update is running. This might damage the device.
8.1 Auto-Update
After having mounted the module and applied the voltage to the central unit, the central
unit detects the modules and checks the software version.
The central unit has a so called “overall release version“. This version contains the cur-
rent software version of the central unit as well as the software versions of the modules.
You can find the “overall release version“ on the Website of the central unit on the „firm-
ware“ tab.
When the software version of a module does not match the “overall release version“ of
the central unit, the central unit does an automatic up- or downgrade of the module.
Thereafter, the module is ready to be used.
Important note
The
“overall release version“ contains all modules developed up to
the date of release
of this firmware
and the corresponding software versions. If a module cannot be de-
tected, yet (
i.e. it is more recent than the Firmware version of the CPU),
this module is
ignored and outlined in red on the Web interface.
In this case, a new u
pdate file has to be installed for the “overall release version“.
If you
want to get the current update file, please contact the iba Support. You will also find it
on the
“iba Software & Manuals“
DVD included in delivery of the module (directory:
0
2_iba_Hardware\ibaPADU-S\01_Firmware).
8.2 Overall Release Version
The „overall release version“ provides information about the software version of the en-
tire iba-modular system. You can find it on the Website of the central unit or in the
I/O Manager of ibaPDA.
Important note
If you require support, specify the „overal
l release version“.
8.3 Update
An update can be installed in two different ways.
Web interface (only with ibaPADU-S-IT-2x16)
ibaPDA
No matter which of the both ways you choose to install an update: the progress of the
update is shown by the LEDs L5 … L8. Beginning with L5, the LEDs are flashing one
after another, at first in orange and then in green and at a slower rate. When the update
is finished, the device will be rebooted.
