IbaPADU-S-IT-16 modular central unit

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.

System Integration and Network Topology

As the central unit, ibaPADU-S-IT-16 must be installed on a dedicated backplane (such as ibaPADU-S-B4S or B1S) and communicate with I/O modules through the backplane bus. Its system integration method is very flexible and supports multiple application scenarios.

1. Typical application architecture:

Pure measurement system: ibaPADU-S-IT-16 serves as the data acquisition front-end, transmitting raw I/O signals to ibaPDA through optical fibers for recording and analysis. This is the most common application mode.

Measurement system with intelligent preprocessing: Run ibaLogic program inside the device to perform preprocessing such as filtering, calculation, and feature extraction on the raw signal. The preprocessed signal is transmitted to ibaPDA along with the original signal via optical fiber. This mode can significantly reduce data volume, improve data quality, and achieve real-time response.

Independent control system: The equipment operates completely independently, relying only on local I/O and internal ibaLogic programs to complete complex control logic, without the need to connect to an upper computer. At this point, it becomes a powerful programmable automation controller (PAC).

Hierarchical automation system: ibaPADU-S-IT-16 serves as a high-speed local controller to perform fast closed-loop control, while exchanging data with a central computer (such as a PC running ibaPDA or ibaLogic) through a high-speed, deterministic ibaNet fiber network to achieve upper level monitoring and optimization.

2. Fiber optic ring network (FO Cascading):

When using the 32Mbit Flex protocol, up to 15 devices that support the protocol (such as ibaPADU-S-IT-16, ibaPADU-S-CM, etc.) can be connected into a fiber optic ring network. Each device is assigned a unique address (1-F) through the S1 rotary switch, forming a high reliability, low latency real-time data sharing network.

Initial startup and configuration

The initial configuration of ibaPADU-S-IT-16 is mainly completed through its built-in web server, which is intuitive and convenient to operate.

1. Default settings and recovery:

User account: Factory default two users: padu (password 1234, with viewing permission) and admin (password 1234, with full configuration permission).

Network parameters: The Ethernet interface defaults to a fixed IP address of 192.168.1.1, subnet mask of 255.255.255.0, and DHCP is not activated.

Host name: The default format is S-IT-16-<serial number>, such as S-IT-16-000050.

Factory reset: Set S1 to "6" and S2 to "9", press and hold the S10 button while restarting the device to restore the network settings and password to factory settings.

2. Network connection establishment:

Through Ethernet: Connect the PC and device to the same network, ensuring that the IP address of the PC is on the same subnet as the device (such as 192.168.1. x). Enter the device's IP address (default 192.168.1.1) or hostname in the browser to access the web interface.

Through fiber optic (32Mbit Flex): In ibaPDA I/O Manager, Autodetect is performed on the FOB-D card link connecting the device, and ibaPDA automatically discovers the device and displays its IP address allocated through fiber optic (such as 172.16.0. x). Enter this IP address in the browser to access.

3. Main configuration of the web interface:

Network Settings (Network tab): Administrators can modify host names, enable DHCP, or set static IP addresses, subnet masks, and default gateways here. FTP/Telnet access permissions can be configured simultaneously.

Time setting (time tab): The device itself does not have the ability to maintain the clock during power failure and needs to be maintained through external buffering or synchronization. Support manual setting of system time, or synchronization with network time servers through NTP protocol, or high-precision synchronization by receiving DCF77 time signals through a digital input channel.

Password Management (Passwords tab): Administrators can modify the passwords of "padu" and "admin" users here.

System update (update tab): Used to upload and install device firmware update files (in. iba format).

IbaLogic Management (ibaLogic tab): Display the current PMAC (ibaLogic runtime) version and manually start/stop the runtime, configure whether to automatically load and run ibaLogic programs when the device starts.

Collaborative application with ibaLogic

The strength of ibaPADU-S-IT-16 lies in its deep integration with ibaLogic-V4, making it a programmable edge computing platform.

1. Platform configuration: In ibaLogic Client, add a new platform through "Tools Platform Configuration", select the device class as "PADU-S-IT-16", and enter the device's hostname or IP address. After establishing the connection, the device can be used as the target platform.

2. I/O configuration: In "Tools - I/O Configurator", click "Update Hardware" to automatically identify the modules installed on the current backplane. Users need to configure signals for the central unit and each module. The key configurations include:

Central unit digital input: Each channel can be configured with an anti shake filter type (DebType_Ch00... 07) and anti shake time (DebTime_Ch00... 07) in the output signal.

FiberOptics_IO: This is the key to communicating with the external world, such as ibaPDA. The input and output protocols must be set to 'External' to enable communication with ibaPDA in 32Mbit Flex mode. At this point, the S1 rotary switch must be set to an address between 1-F.

Buffered Access: If you need to collect signals at a sampling rate of less than 1ms, you must enable 'Buffered Access'. After activation, the signal will be provided to the ibaLogic program in array form with timestamp information attached.

3. Program design: After completing the configuration of I/O signals and assigning them to the program, functional blocks (such as DATFHIR LOWRITE) can be used in the programming interface for logic design, mathematical operations, and process control. For example, the measurement data can be directly saved to the local RAM disk of the device (default path C: dat) using DATFILE&WRITE, and then downloaded remotely through Ethernet using ibaDatCoordinator software.

4. Program deployment: After completing the program compilation, select "Evaluation - Store Program to PMAC" to load the compiled program onto ibaPADU-S-IT-16. If "AutoStart" is enabled in the "ibaLogic" tab of the web interface, the device will automatically load and run the program every time it is powered on, achieving true independent operation.
