IbaFOB io ExpressCard fiber optic interface card

Removal steps:

Disconnect the fiber optic cable.

Gently push the card to unlock it, then carefully pull it out of the slot.

Deep analysis of software configuration and application

Configuring the card in ibaPDA-V6 software is a crucial step in achieving data collection.

I/O Manager Configuration

Start the ibaPDA-V6 client and go to "Configure ->I/O Manager". Select ibaFOB io ExpressCard in the left tree structure.

Configuration tab:

Interrupt mode: For single card laptop applications, "Master mode internal" is usually selected.

Enable status: Check the "In use" option to enable ibaPDA to recognize and use the card.

Onboard watchdog: optional feature. After activation, if data collection stops for more than 2 seconds, the board will generate an alarm message, set the output value to zero, and light up the red LED indicator light. This function can be used for external system monitoring of the operational health of ibaPDA.

Information tab:

This tab provides board hardware information and loaded firmware versions. Important reminder: Firmware updates must be carried out under the guidance of the IBA technical support department and should not be operated arbitrarily.

Link status monitoring

The software interface provides detailed diagnostic information for each fiber link (Link 0). These pieces of information are crucial for troubleshooting communication failures.

Communication status area:

Communication status: Displaying "OK" indicates that the fiber optic communication is normal, that is, the received data message matches the mode of the link configuration.

Detected link protocol: Display the link protocol automatically detected by the board (such as 3.3 Mbit/s, 32 Mbit/s, or "?").

Telegram/Error counter: Display the number of correctly received and erroneous messages (such as checksum errors) respectively. If the error counter continues to increase, it indicates interference or poor connection in the fiber optic link.

Detailed analysis of diagnostic information (differentiated by protocol):

3.3 Mbit/s or 2.0 Mbit/s mode:

FO signal strength: displays the strength of the fiber optic input signal (range 0-255), with higher values indicating stronger signals.

Device ID: Display the ID of the last device on the link.

5.0 Mbit/s mode:

Device firmware date: Displays the firmware date of the connected device.

Gain and filter table: suitable for ibaPADU-8-ICP devices, displaying their configured gain and filter settings.

32Mbit Flex mode:

Mode: Indicates whether the connection mode is "Ring" (bidirectional closed loop) or "Open chain" (open chain, only input connection).

Round trip delay: In a closed-loop fiber optic ring, the cycle time of data packets is related to the number of devices in the ring.

Image generation area:

This section describes the status of the data buffer that the board writes to the system memory through DMA.

Images processed at interrupt: Displays the number of images available in the DMA buffer at each interrupt.

DMA buffer empty/Dropped images: These two counters are key to diagnosing system performance bottlenecks. DMA buffer empty increment indicates that the buffer is empty, usually occurring when the fiber link is disconnected. Dropped images increment is a serious warning, indicating that the DMA FIFO of the board is full and unable to transfer data over the PCI bus. This suggests that the PCI bus is overloaded or the system is not responding in a timely manner.

Operation mode and device compatibility

The flexibility of ibaFOB io ExpressCard is reflected in its support for multiple operating modes, enabling it to connect almost all iba field devices.

Operation Mode Link Speed Maximum Signal Number Sampling Time Typical Equipment Application

Unidirectional fiber input mode

2.0 Mbit/s 32 INT+32 Digital ≥ 1 ms old ibaPADU (S/N<1000)

3.3 Mbit/s 64 INT + 64 Digital ≥1 ms ibaPADU 8/16/32

5.0 Mbit/s 8 INT + 8 Digital ≥50 μs SIMATIC TDC LO5

32 Mbit/s 512 REAL + 512 Digital ≥800 μs ABB AC 800PEC (1 ms)

8 x (64 INT + 64 Digital) ≥1 ms ibaBM-COL-8i-o (1 ms)

Bidirectional fiber mode (requires output link)

5 Mbit/s 8 INT + 8 Digital ≥40 μs ibaPADU-8-M, ibaPADU-8-ICP

32Mbit Flex variable * ≥ 10 μ s ibaPADU-S-IT

*Note: Under the 32Mbit Flex protocol, the packet length can be variable, for example, 72 bytes can be transmitted at a sampling time of 25 μ s, or 3147 bytes can be transmitted at a sampling time of 1ms.

Troubleshooting and LED indicator lights

The four LED indicators on the front end of the card provide intuitive hardware status feedback:

Run (green): Flashing indicates that the power is turned on and the channel function is normal; Constant shutdown means that the controller has stopped (due to hardware failure).
