ibaBM-CAN CAN / CANopen Bus Sniffer

Product basic information

Product positioning: ibaBM CAN is a CAN/CANopen bus sniffer developed by iba AG in Germany. Its core function is to extract CAN bus message measurement data and CAN bus diagnosis. It can seamlessly connect to existing CAN buses without changing their physical characteristics, and supports independent connection of 2 CAN buses and independent control of terminal resistance;

Version and Certification: The manual version is Issue 1.1 (January 20, 2014), and the equipment complies with European standards and CE certification, with order number 13.122000;

Core advantage: The unique microsecond level CAN bus cycle time measurement function can detect faults such as bus overload and insufficient priority of important IDs. The measurement data can be graphically displayed in ibaPDA-V6 and used to trigger control.

Core Key Characteristics

Specific parameters/functions of characteristic categories

Connect two CAN buses (Bus0/Bus1) to the CAN bus, with speeds ranging from 10kbit/s to 1Mbit/s; Supports 11 bit standard IDs (0x1~0x7ff) and 29 bit extended IDs (0x1~0x1f ff ff ff)

The data transmission capacity can transmit 512 analog signals per millisecond (supporting BYTE/INT/WORLD/DINT/DWORD/FLOAT, large/small end)+512 digital signals; Analog signals support linear conversion of Gain/Offset to physical units

Communication interface fiber optic: ibaNet 32Mbit/s TX interface (RX not functional), maximum transmission distance without relay 2000m, needs to be matched with ibaFOB-D series fiber optic input card;

Configuration: Ethernet TCP/IP (10/100Mbit/s), USB 2.0, used for parameter configuration and firmware updates

The diagnostic function measures the cycle time (μ s) of each ID message transmission and diagnoses the deterministic behavior of the diagnostic bus; Support timeout configuration, send the last value or default value when timeout occurs

Bus adaptation can be accessed as a bus terminal, intermediate node, or loop through mode; Two independent CAN bus terminal resistors (120 Ω) switch, which does not affect the original CAN bus communication

Equipment Installation and Disassembly

The device is installed vertically on DIN rails, and there is no need to open the device during the entire operation process (there are no maintenance parts inside, and opening the cover will result in loss of warranty). The core steps are:

Installation steps

Press the DIN rail buckle on the back of the device, insert the device into the rail and secure it;

Grounding the device through shielded connector X29 as needed;

Connect a 24V DC power supply (pay attention to polarity), then connect the fiber optic cable (TX connected to ibaFOB-D input card) and configure the interface (Ethernet/USB) in sequence;

According to the CAN bus access mode, set the S4/S5/S6 switch (terminal resistance/direct mode).

Disassembly steps

Turn off the device power switch S11 and disconnect all external connections (power, fiber optic, configuration interface, CAN bus);

Press and hold the top of the device with one hand, and press the bottom buckle with the other hand and lift it up to detach the device from the DIN rail.

Equipment Structure and Core Components

The device consists of three parts: interfaces, control components, and indicator components. Each component has clear functions, and the core components are as follows:

Core interface (including pin definition)

Interface name identifies key parameters of core functions

CAN bus interface X40 (Bus0)/X41 (Bus1) is connected to 2 CAN bus D-Sub9 pins, Pin2=CAN_L, Pin7=CAN-H, Pin3=GND, Pin5=shielded

Fiber optic interface RX/TX data transmission to ibaPDA RX with no function, TX=32Mbit/s ibaNet, ST connector, 62.5/125 μ m fiber optic

Ethernet interface X22 TCP/IP configuration/firmware update 10/100Mbit/s, unique MAC address, device name format can_nnnn (nnnn is the last 4 bits of MAC)

USB interface X23 local configuration/firmware update USB 2.0, requires the installation of a dedicated NDK driver, fixed IP 192.168.0.1

Power interface -24V DC power supply 2-pin Phoenix terminal, 24V DC ± 10%, maximum 600mA

Shielding grounding X29 equipment grounding should be connected as needed to match the shielding grounding requirements of CAN bus cables

Control Components

Component identification type core function

The power switch of S11 ship type switchgear does not affect CAN bus communication when turned off

S1/S2 rotary switch combined with S10 to restore factory settings (S1=6, S2=9)

Press the reset button on S10 to restore factory settings in conjunction with S1/S2

S4 dip switch Bus0 terminal resistor (120 Ω) switch, ON=ON

S5 dip switch Bus1 terminal resistor (120 Ω) switch, ON=ON

S6 dip switch Bus0/Bus1 direct switch, ON=two bus connections (loop mode)

Indicator element (LED)

The device includes three types: device status LED, communication interface LED, and CAN bus LED. Each status has a clear meaning, and the core is as follows:

Device status LED: Run (green, 1Hz flashing=normal, constantly on/off=fault), 32Mb (white, on/flashing=fiber optic communication), Stop (red, on=internal fault, flashing=startup error);

Communication interface LED: Ethernet (green=connected, red=faulty), USB (green=connected, red=faulty), CF (no function, only card detection);

CAN bus LED (Bus0/Bus1): Run (green=controller normal), Bus (yellow=bus communication), Act (white=configuration loaded successfully), Err (red=bus error, flashing=occasional fault).

CAN bus system integration mode

IbaBM CAN supports three CAN bus access modes without modifying the original bus structure. The switch configuration corresponds to the access method:

Applicable scenarios for access mode S4/S5 settings S6 settings Key instructions

The bus terminal device connected to the CAN bus terminal plug corresponds to the bus ON (opening the terminal resistor) OFF, which can simultaneously connect to 2 independent CAN buses (Bus0/Bus1 each connected to 1)

Bus intermediate devices connected to CAN bus intermediate nodes are all turned off (terminal resistors are turned off), which does not affect the original communication of the bus and only collects data

The loop through device is connected to the CAN bus with both end plugs turned off (terminal resistance turned off) and turned on (direct connection turned on). Only one CAN bus is supported, and Bus0/Bus1 connection is a loop

Core Configuration Method

The device configuration is divided into three parts: physical switch configuration, software configuration (ibaPDA-V6), and web interface configuration, which work together to achieve full functional configuration:

Physical switch configuration

Terminal resistance: S4/S5 independently controls the 120 Ω terminal resistance of Bus0/Bus1, and the bus end needs to be turned on;

Direct mode: When S6 is turned on, Bus0/Bus1 are connected, only used for loop direct mode;

Factory reset: S1=6, S2=9, press and hold S10 and restart the device, release after 10 seconds to clear network/password configuration (signal parameters. csv retained).

ibaPDA-V6 software configuration (core, used for signal acquisition)

To be completed in ibaPDA-V6 I/O Manager, the core steps are:

Connect the device power supply, fiber optic cables, and configuration interfaces, start ibaPDA-V6, and open the I/O manager;

Select ibaFOB-D fiber optic card, add ibaBM CAN module (supporting automatic detection), configure global parameters such as bus baud rate, timeout, IP address, etc;

Add Sniffer submodule under ibaBM CAN module to configure the bus for analog/digital signals COB ID、 Data type, address, etc;

Activate the configuration and verify it, and the configuration will be automatically transferred to the non-volatile memory of the device.

Key configuration items:

Analog signal: supports 6 data types including BYTE/INT/FLOAT, can set Gain/Offset linear conversion, and can choose the final value/default value when timeout occurs;

Digital signal: Positioned by byte offset and bit number, supporting two data sources: IO data/status information;

Timeout configuration: Supports global bus timeout and individual COB ID independent timeout (microsecond level).
