Central units 
The iba modular system acquires and processes measurement signals and is - with the appropriate signal output modules- also suited for control applications. The modular concept is based on a module rack with backplane bus for one central unit and up to 4 input and output modules. With user-specific central units, various applications can be implemented. - ibaPADU-S-CM is a pure communication unit for the input and output of different signals.
- ibaPADU-S-IT has an integrated processor and an internal memory and is suitable not only for the fast acquisition of measurement values but also for intelligent processing of signals and system controls.
- ibaCMU-S is the metrological core for Condition Monitoring applications.
- ibaPQU-S is a Power Quality Unit for monitoring the network quality with the highest precision.
Moreover, the central units offer 8 digital inputs with an input signal range of ±24 V. The system includes several I/O modules for analog and digital inputs and outputs as well as for SSI and pulse transmitters. All I/O modules work with sampling rates of up to 40 kHz absolutely time-synchronously. Due to the modular technology and the broad range of I/O modules, the iba modular system can be flexibly adapted to the respective requirements. The areas of application depend on the central unit that is used, the plugged modules and the used iba-applications. Typical examples are: - Acquisition of measurement values with and without pre-processing
- Signal management
- Controlling
- Fast drive and position control
- Condition Monitoring
- Data logger (Transient Fault Recorder)
- Mill chatter monitoring and excentricity analysis
- Power Quality Monitoring
The I/O modules are detected automatically by the central unit. The iba modular system can be configured by means of the I/O Manager in the ibaPDA application or the I/O Configurator in the ibaLogic application. The central unit requires a power supply of 24 V DC. The power supply of I/O devices is provided internally by the backplane bus. A synchronization channel on the backplane guarantees isochronous sampling of all I/O modules.
The following table gives an overview over the current I/O modules and how they may be combined with the different central units.  All central units can send and receive the ibaNet protocol 32Mbit Flex bidirectionally. The signal acquisition can be done with up to 40 kHz and can be selected variably for each modular system. Moreover, some central units support the previous 3Mbit and 32Mbit ibaNet protocols.
32Mbit Flex protocol With 32Mbit Flex, the measurement data and the configuration data are transferred bidirectionally via 2 FO cables. A LAN connection for transferring the configuration data - as for the previous ibaNet protocols - is not required. 32Mbit Flex works with a data transfer rate of 32 Mbit/s and supports up to 15 „flex-capable“ devices connected in a ring topology. The size of the data telegrams is flexible, as long as the overall data volume of 4060 Byte is not exceeded. The sampling rate can be set flexibly for the modular systems at up to 40 kHz. Every system can work with its own sampling rate. The sampling rates only have to be a multiple of the basic sampling rate and the whole volume in the FO conductor must not be exceeded. In principle, the following rule applies: The less data is transmitted, the higher the possible sampling rate. - Modular data acquisition and control system
- Graphical programming by the user (IEC61131)
- Stand-alone system with ibaLogic onboard
- Optional acquisition of raw data and values calculated with ibaPDA
- Control system, Soft PLC
- Time-synchronization possible (NTP, DCF77)
- Data are stored on the device (110 GB SSD)
Due to the integrated processor and the large RAM, the ibaLogic control programs can be loaded in
ibaPADU-S-IT and executed in a temporally deterministic way with a cycle of 1 ms. After having been programmed with ibaLogic, an iba modular system with ibaPADU-S-IT as central unit can work autonomously without a connection to the ibaLogic development computer. In case of an autonomous measurement data acquisition, the measurement data can be stored as files in the .dat format on the local hard disk and then downloaded via the network.  Moreover, ibaPADU-S-IT can transfer in parallel raw data and characteristic values calculated from the measurement data in real-time to the ibaPDA system. Thus, e.g. a local pre-processing of the signals like e.g. digital filtering or FFT calculations can be done with an ibaLogic application in the central unit.
In addition to the ibaMS-modules, a huge number of different peripherals can be connected and acquired and processed with ibaPADU-S-IT. This includes process data from external systems, that are fed in e.g. with ibaNet periphery over FO cable. The internal ibaLogic application allows the selection of all raw data and user-specific processing of these data with freely programmable function blocks. Moreover, an Ethernet connection provides access to internal signals and allows control applications to run.  Measuring application (capturing, recording, analyzing)- Signal recording with ibaPDA

Sample-synchronous acquisition
In an iba modular system, the signals of all connected modules are acquired absolutely time synchronously. If several systems are connected in an FO ring topology, the run time is taken into account in the FO conductor and the data are acquired sample-precisely on the ibaFOB card in the ibaPDA system. This means that all channels which are acquired by means of an ibaFOB card, are also recorded sample-synchronously in ibaPDA. A prerequisite for the data acquisition in the ring topology is the ibaNet protocol 32Mbit Flex.

ibaCMU-S is the metrological core of an iba modular system for Condition Monitoring applications. The central unit is extended by I/O modules which are suited for Condition Monitoring purposes, especially with analog current and voltage inputs and modules for IEPE sensors. The system is configured by means of the Condition Monitoring Center ibaCMC. ibaCMC is a Web-based application which serves as analysis and configuration backend for ibaCMU-S systems. In ibaCMC, the user can configure the plant that is to be monitored, specify analyses and define alarm functions as well as report generation. For larger plants or a cross-plant solution, several CMUs can be used, that are configured in a centralized Condition Monitoring Center.  ibaCMU-S acquires the raw data of the connected sensors time synchronously with up to 40 kHz and processes them in real-time. The central unit exchanges data with the automation environment and carries out internally a major part of the signal analysis. The calculation results and raw data are stored in the internal memory and optionally transferred to an ibaPDA system via FO conductor. The outputs can be used for warning and alarm messages, but also for an automatic adaptation of parameters in the plant control.
ibaCMU-S can also be operated without an ibaPDA system. On the central unit, a Web interface is available which offers comprehensive diagnostic functions. Optionally, slower process signals can be interfaced using ibaNet750 modules. - Modular Power Quality Monitoring System for monitoring the network quality at the highest precision
- Net-synchronous measurement

 An essential basis for improving the network quality and the availability of the networks is the precise knowledge and analysis of all decisive quality parameters. ibaPQU-S is a compact system for monitoring the network quality and for analyzing failures, it realizes all measurement tasks that are relevant
therefore. By means of the determined characteristic values, the network failures can be analyzed in detail and the network operation can be organized more efficiently.
ibaPQU-S is suited for DC networks, for networks with 50 Hz and 60 Hz as well as for special networks like e.g. the railway network with 16.7 Hz. The system measures raw values like current and voltage net-synchronously and calculates internally the characteristic values which are relevant for the net quality according to IEC 61000-4-30 (class A). For the Power Quality function, selected input modules are suitable: - ibaMS3xAI-1A
- ibaMS3xAI-5A
- ibaMS3xAI-1A/100A
- ibaMS4xAI-380VAC
- ibaMS8xAI-110VAC
- ibaMS16xAI-10V
In ibaPDA, any triggers can be configured for triggering event-related measurements and acquiring failures. For a detailed analysis, the data are acquired at a high resolution with an appropriate lead-time or follow-up. Moreover, failures can be indicated by means of an alarm function. With ibaAnalyzer, long-term trendings and comprehensive reports can be created, that prove e.g. the compliance with the EN 50160 standard. The following characteristic values are determined: - Voltage, current (raw values)
- Frequency (all times complying with standards)
- RMS and maximum value, rectified value, form factor, crest factor (all times complying with standards)
- FFT (Harmonics up to 50, Interharmonics up to 50, beginning with 200 ms all times complying with standards)
- THD (harmonic distortion, beginning with 200 ms all times complying with standards)
- Phase values (V/I phase angle to the reference voltage)
- Power values (active power, apparent power, reactive power, electric energy, power factor for single conductors and also the whole network)
- Symmetric components of three-phase-systems (Positive sequence, negative sequence, zero sequence) and voltage balance
- Flicker (short-term, long-term)
