IbaPADU-S-IT-16 Central Unit: The Core of Modular Measurement and Control Platform

Product Overview and Core Positioning

IbaPADU-S-IT-16 is a high-performance central processing unit and the core component for building the ibaPADU-S modular system. It is based on a powerful 1.6 GHz Atom processor and Windows CE 5.0 operating system, designed specifically for high-speed applications such as measurement technology, signal processing, and real-time control. Its biggest feature is that it is not only a front-end for data collection, but also a platform with local intelligent processing capabilities.

Core functions and positioning:

The brain of modular systems: ibaPADU-S-IT-16 is connected to up to 4 input/output modules through a backplane bus, forming a flexible and expandable measurement and control system. Users can combine different I/O modules according to their specific needs to achieve complex closed-loop control from simple signal acquisition.

Local intelligent processing (edge computing): the device has built-in ibaLogic-V4 runtime system (PMAC). Users can load the compiled ibaLogic program into the device, enabling it to run independently, perform real-time preprocessing, filtering, calculation, and even execute local control logic on the collected signals. This edge computing capability greatly reduces the burden of the upper computer (such as ibaPDA), and achieves very low latency response.

Seamless integration with ibaPDA: As part of the iba ecosystem, ibaPADU-S-IT-16 can be connected to the ibaPDA data acquisition system via a high-speed fiber optic interface (ibaNet). Both raw I/O signals and signals preprocessed by ibaLogic can be transmitted in real-time to ibaPDA for recording, analysis, and visualization.

Durable and Maintenance free Design: The equipment features a sturdy casing design without fans or rotating parts, making it almost maintenance free and ideal for long-term stable operation in harsh industrial environments.

Hardware interface and functional characteristics

The hardware design of ibaPADU-S-IT-16 is compact, with rich interfaces, fully considering the connection and debugging needs of industrial sites.

1. Front panel interface and indicator lights:

Digital input (X5): Provides 8 electrically isolated digital input channels with reverse polarity protection. The input signal range is ± 60V for permanent safety, and the logic level meets the 24V standard. Each channel supports configurable debounce filters, including multiple modes such as "edge extension" and "edge delay", effectively suppressing signal jitter.

Power interface (X14): Connect an external 24V DC power supply (± 10%) through a 2-pin spring terminal. The maximum power consumption of the device itself is 20W. When fully loaded with I/O modules, it is recommended to have a power capacity of 3A.

Buffer voltage interface (X30): Starting from hardware version B3 and software version V02.06.001, it supports external buffer voltage (typical 12V DC, 9-15V). In the event of an external power failure, this interface can provide a brief buffer for the internal clock and fiber optic communication link of the device, ensuring time synchronization and network communication continuity.

Status indicator light:

L1 (green): Equipment operating status. Regular flashing indicates normal operation; Fast flashing indicates being in system programming or update mode.

L2 (yellow): ibaLogic runtime status. Flashing indicates that PMAC has started and the program is running.

L3 (white): Fiber optic receiving status. Constant illumination indicates normal fiber reception.

L4 (red): Equipment malfunction indication. If it is constantly on or flashing, it indicates an internal application failure of the device and support needs to be contacted.

L5-L8: Used for status and progress indication during network settings or firmware updates.

L10-L17 (green): corresponding to the status of 8 digital input channels, lit up indicates that the input is logical "1".

2. Top and bottom interfaces:

Fiber optic interface (X10 TX, X11 RX): uses standard ST connectors for high-speed data exchange with ibaPDA or other ibaNet devices. Supports multiple ibaNet transmission protocols such as 3Mbit, 32Mbit, and 32Mbit Flex, with a maximum sampling rate of 40kHz. The maximum transmission distance depends on the protocol and fiber type (500m for 32Mbit and 2000m for 3Mbit).

Network interface (X22): Standard 10/100 Mbit/s Ethernet port, used for device parameter configuration, web interface access, and communication with ibaLogic development environment.

USB interface (X24, X25): Two USB host interfaces reserved for future functional expansion.

Operating components:

Power switch (S11): Control the power on/off of the device.

Rotary switches (S1, S2): used to set the fiber ring network address (in 32Mbit Flex mode, S1 defines the device's position 1-F in the ring network) and to perform special functions in conjunction with S10 (such as restoring factory settings and directly setting IP addresses).

System Function Button (S10): Used in conjunction with a rotary switch to restore factory settings, directly set network parameters, or delete loaded ibaLogic programs.
