IbaPADU-S-IT-16 modular central unit

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:
