Known Issues

This section describes bugs and issues that have been reported and that the development team is currently working on. For further questions, see Frequently Asked Questions (FAQ).

Scan

• Some IO-Link devices take longer to be recognized by the IO-Link network module. #55747

  Workaround

  Rescanning IO-Link devices can remedy the situation.

• A subsequent change of the connection type of an IO-Link network module from http to https can lead to the status of connected devices not being updated by the Continuously check connection status function. This problem will be fixed for the next release. #167088

  Workaround

  Rescanning IO-Link devices can remedy the situation.

General information

• When the language is changed from German to English, the context menu language is still German. #132571

  Workaround

  Setting the language to English and restarting the application will fix the problem.

• During the BET installation, all network drivers and network adapters are restarted. This can have a particular impact on real-time applications such as soft PLC programs that rely on uninterrupted network connectivity or where there is an active VPN connection. #135670

  Workaround

  your system and pose security risks, including accidents or data loss. We recommend that you close all critical applications, especially real-time or mission-critical software, before proceeding with the installation. Save your work and make sure you are aware of all possible consequences.

• If a static port has been set in the user settings of BET , crashes may occur if BET is started multiple times in parallel. #162124

Topology

• After the topology import all parameters are marked as “changed” with a yellow triangle. This enables immediate writing of all parameters after importing the topology. #132583, #49920

  Workaround

  The parameter values are the values that were read when exporting the topology. Press WRITE TO DEVICE to write all values or execute READ FROM DEVICE to read the current values.

• Devices are displayed as “not connected” although they are connected. #242265

  Workaround

  Repeat the update. By right-clicking on the topology or in the detail view.

• If a device requires a “login”, starting a login process in the detail view will not revert to the login data for the device that already exists in the database. #94602

  Workaround

  Log in by entering your username and password.

Parameterization of IO-Link devices

• Error message: Parameter cannot be written, although the parameter is shown as writable. This problem can occur if the parameter is of type ArrayT, TimeT or TimeSpanT. #132888

  Workaround

  Use the “ISDU parameters” tab.

• Diagnosis menu/observation is displayed without entries: The IODD for this device contains process data mapped as ISDU parameters. However, the process data is only displayed at BET within the “Process data” tab. Since the interface for the device is automatically built from the IODD, there may be no data in the “Diagnostics” tab.

• BNI IOL sensor/actuator hubs: Extension port cannot be switched on via IODD. The settings for the extension port are not included in the IODD. Therefore, they cannot be changed via the normal parameters. If a PLC is connected, the correct setting of the hubs is generated by the validation of the devices. #132591

  Workaround

  • If a PLC is connected, the correct setting of the hubs is generated via the validation of the devices.

  • If you do not have a PLC connected at the moment but want to switch the hubs, you can use the option to change the index and subindex via the web interface of the Balluff-IO-Link network MOdul or via the “ISDU parameters” tab. As a rule, the index 0x55 must be changed. More detailed information can be found in the instructions of the hubs.

• Parameters of IO-Link Devices are marked red (not writable). It can happen that some parameters in the “Parameters” tab of the IO-Link device view are marked red and cannot be written for an IO-Link device. This problem usually occurs if the firmware of the device does not match the IODD version. #132593

  Workaround

  In this case, please import another version of the IODD file that matches your device and update the device in the device view.

• Parameterizing many parameters of a device at the same time does not work completely. If, for example, all parameters are set to “changed” and these are to be written via WRITE TO DEVICE. #132597

  Workaround

  Write the parameters marked with “Error” (red triangle) again individually with WRITE directly at the parameter.

• When displaying parameters in the detail view and when comparing parameters, it can happen that contents become illegible. The reason for this is that in some languages (mostly Japanese) the standard ASCII table was not used when describing the parameters. #19640

• If a parameter of type TimeSpanT is entered, inaccuracies may occur in the value entered. For example, 30 days can be written one millisecond higher or lower than entered. #173446

• When importing a topology with Ethernet IP network modules and writing the parameters at the same time, a warning may be displayed indicating that the port settings have not been written. However, the port settings are written correctly. This is only a display error. The problem will be fixed in the next releases. #89953

IODD update

• After updating an IODD, it may happen that the associated device in the topology displays an incorrect status. #3161

Workaround

Refresh the devices after an IODD update using Check connection status continuously in the main view.

Parameterization of IO-Link network modules

• The BNI web interface shows more port parameters than the BET port options menu. Some of the IO-Link network modules provide more port configuration options within the web interface panel than in the port configuration panel. This is because these settings cannot be retrieved from the network module via the current interface of BET . #132600

  Workaround

  Log in to the web interface of the IO-Link network module to configure these additional port parameters.

• Port configuration of IO-Link network module does not allow configuration of PIN 2. For some IO-Link network modules, the configuration of pin 2 on ports cannot be read. This problem is caused by faulty device-specific files (IODD), over which the BET has no control. However, efforts are being made with the manufacturers to correct this problem. #132886

• The display of the legend on mouseover may behave differently. It may happen that the legend is not displayed. #77361

  Workaround

  Move the mouse pointer outside the field and then slowly move it back inside the field.

Device List

• When you export the device list, all columns are exported, even those that are currently excluded from display. #132885

Firmware update

• Since March 2024, you have received encrypted firmware for the following network modules:

  • BNI00HL

  • BNI00K4

  • BNI006A

  • BNI008M

  • BNI00HM

  • BNI00HW

  • BNI00H4

  • BNI00K5

  The new firmwares offer an increased security standard. These encrypted firmwares can no longer be replaced by the previously unencrypted firmwares. Upgrading to encrypted firmware is only possible if the firmware used on the network module has been prepared for such an upgrade.

  If an attempt is made to update from an unencrypted firmware that is not designed for an upgrade to an encrypted firmware to an encrypted firmware, this will result in a failed update.

  If an attempt is made to set an encrypted firmware from an unencrypted firmware, this will result in a failed update.

• For BNI00HL firmware version 1.1.4 and BNI00HM firmware version 4.8.4 is not supported:

  • Correct visualization of the port status in the master view

  • Visualization of the process data of all connected devices in the master view

• When updating the firmware of a BNI00HL with FW 1.0.x to FW 1.1.4, BET displays an error at the end of the update because the device is reset to the factory settings and BET cannot find the device after the reset (no IP address in Profinet and default Profinet name). The firmware is saved on the device despite the error message.

  Workaround

  • Resetting the settings indicates a successful update

  • After the update, perform a new network configuration for the devices and change the IP address.

• When updating the firmware of a BNI00HM with FW 1.1.x to FW 4.8.4, BET displays an error at the end of the update, as the device is reset to IP 192.168.1.1 and BET cannot find the device after the reset, unless the update has already been carried out with this IP. The firmware is saved on the device despite the error message.

  Workaround

  • Resetting the settings indicates a successful update

  • After the update, perform a new network configuration for the devices and change the IP address.
