Version 2.15.6

Release Date: 28. November 2023

Main Features

The self-signed OPC UA client certificates generated by the ioHandler for OPC-UA shipped with 2.15.5 were invalid and thus not accepted by some PLCs. This issue has been resolved.

If you have previously installed WebIQ 2.15.5 and upgrade to WebIQ 2.15.6 you have to manually delete the client certificate files:


If you have previously installed WebIQ < 2.15.5 you do not need to and should not delete these files!

Please note that when you delete these files the newly generated client certificate has to be trusted usually on the OPC UA server!

Version 2.15.1

Release Date: 15. September 2023

Important Update

WebIQ 2.15.0 erroneously only utilized unencrypted connections to the OPC-UA server, unfortunately. Because a fallback to unencrypted connections happened by default we have both fixed the initial issue and changed the way encryption is handled.

When updating from a previous WebIQ version before 2.14.0 please update first to 2.14.3 - otherwise WebIQ will not work anymore on your system. This will be fixed with the upcoming 2.15.2 release.
BREAKING CHANGE If you have been using unencrypted connections to your OPC UA server and you want to keep using unencrypted connections after updating to WebIQ 2.15.1 you have to manually modify the IO Handler configuration in the IO Manager by setting both Message Security Mode and Security Policy to None manually, otherwise WebIQ will support encrypted connections to the OPC UA server only and you might not be able to access items from the server until you change this setting.
In general we recommend to only use encrypted connections to the OPC UA server

Please note that this release only updates the OPC UA IO Handler, there are no changes in WebIQ Server, WebIQ Designer and WebIQ Visuals so these will still be shipped in version 2.15.0

WebIQ Server

  • WEBIQ-3977 IO Manager: Message Security Mode 'automatic' no longer contains 'none' so it will not fallback automatically to non-encrypted communication if encryption fails

  • WEBIQ-3975 Fix: WebIQ 2.15.0 did not support encrypted connections to OPC-UA servers anymore and tried to fall back to unencrypted connections, see WEBIQ-3977

Version 2.14.3

Release Date: 22. June 2023

Main Features

  • Bugfix release mainly for WebIQ Server

WebIQ Server

  • WEBIQ-3863 Fix: Internal items (using the internal IO Handler) were not stored persistently anymore.

WebIQ Designer

  • WEBIQ-3866 Fix: HMI Project Starter: contained some locale settings that might have overwritten some default localizations

  • WEBIQ-3845 Fix: IQ Text: when opening the localization selection dialog and clicking OK without selecting a localization 'null' was inserted

Version 2.14.1

Release Date: 26. May 2023


  • Bugfix release mainly for ctrlX

WebIQ Server

  • WEBIQ-3846 Fix: When an alarm was raised the acknowledgement was not set correctly anymore

  • WEBIQ-3807 Fix: Bugfix for a freeze of WebIQ 2.14.0 on ctrlX: disabled SSDP/UPNP auto-discovery on ctrlX for now, added optional new parameter --disable-upnp for WebIQ Server in general

Version 2.14.0

Release Date: 02.05.2023

Main Features

  • Alarm Manager: alarms can now be duplicated and imported and exported

  • Widget templates and composite widgets can now be imported and exported as instances

  • All Roboto fonts can now be used in IQ styling for all widgets

  • WebIQ Server project configuration database (project.sqlite) has been removed and replaced by JSON files for better versioning of changes

  • The server configuration tool (connectcfg) has been removed as all functionality is now available through the Runtime Manager

  • Connections to OPC-UA datasources can now be forced to be encrypted with disabling unencrypted fallbacks

  • New widget IQ Trend-Set Select for configuring different trend sets through the HMI

Release Notes

  • Updated supported minimum browser versions to these (or compatible):

    • Chrome 80 (released 04.02.2020)

    • Firefox 74 (released 10.03.2020)

    • Edge 80 (released 07.02.2020)

    • Safari 14 (released 16.09.2019)

    • Opera 67 (released 25.02.2020)

  • As the configuration tool connectcfg has been removed it can no longer be used. However, this did not work with WebIQ 2.13 already on Linux.

  • If your HMI is using prepared SQL statements which you have manually added to project.sqlite before and which reference project.sqlite itself (the "target_database" column contains "project") your corresponding code has to be modified, because as the database does not exist anymore you cannot perform SQL queries on (now new) JSON files. Instead, there are two options:

    1. your code has to include the SQL statement itself used to fetch all other associated SQL statements before from the database

    2. you have to use the Server API ( to retrieve the corresponding SQL statements. Before you have to add an ACL entry for the list/read command.

In any case, please contact us if you are affected by this issue so we can ensure a smooth transition. Please note that this issue affects only a very small amount of users and cannot be caused by working with WebIQ Designer - you would have to manually edit the database file project.sqlite to cause that issue.

WebIQ Installer

  • WEBIQ-3688 Added '(incl. Runtime)' to the development system in the installer to point out that WebIQ Server will also be installed on a development environment

WebIQ Server

  • WEBIQ-3720 Fix: [SECURITY] SQLite database file could be downloaded through the browser. As these include the unencrypted credentials for OPC-UA servers this is a security vulnerability and all OPC-UA server credentials should be considered compromised and changed immediately.

  • WEBIQ-3631 Fix: An error message was logged when a websocket was not closed correctly that was not really an error and has thus been removed

  • WEBIQ-3650 Fix: The Alarm List did not always show results when the server was running on Linux

  • WEBIQ-3664 Fix: When using source timestamps for items in a trend no data was recorded

  • WEBIQ-3699 Fix: Runtime Manager: when the connection was lost to WebIQ Server the error message was not displayed correctly

  • WEBIQ-3718 Fix: Improved error log in case WebIQ Designer sends an invalid request to WebIQ Server

  • WEBIQ-3791 Fix: Runtime Manager: No error message was shown when connect.sqlite could not be written due to incorrectly set file permissions by the user.

  • WEBIQ-3797 Fix: A simulation item with the simulation function 'randomramp' was changed to 'ramp' automatically and three parameters were added.

  • WEBIQ-3804 Fix: Runtime Manager: when a master license key with multiple licenses with one license containing an infinite number of tags had been selected, 0 was shown instead of unlimited for tags - this was only a display error.

  • WEBIQ-3805 Fix: Path placeholders like %configpath% were replaced by their value and then stored. This resulted in the complete path in the configuration instead of the one with placeholders which is not desirable.

  • WEBIQ-3806 Fix: When an alarm had been deleted in WebIQ Designer it remained active and could be triggered. On trigger an error was logged in the logfile.

  • WEBIQ-3809 Fix: It was no longer possible to use median aggregation in a trend - if such a trend was used in a Trend display widget no lines were drawn

  • WEBIQ-3818 Fix: Trend aggregation using rolling median returned wrong data after some time

  • WEBIQ-3825 Fix: Process Data Manager: when browsing an OPC-UA server not all nodes were accessible sometimes

  • WEBIQ-3367 Almost all configuration options for an HMI project are now available as JSON files for easier versioning - project.sqlite has therefore been removed.

  • WEBIQ-3680 Demos and News can now also be accessed with a proxy configured on the system

  • WEBIQ-3723 It is now possible to enforce an enrcypted connection to the OPC-UA server

  • WEBIQ-3761 When certain errors occurred that related to Windows WinHTTP interface the exact Windows error code was not shown before - this has been added now

  • WEBIQ-3762 Added support for the reverse proxy on ctrlX systems

  • WEBIQ-3785 License activation did not work when the Windows "WinHTTP Web Proxy Auto-Discovery" (WPAD) service had been disabled. WebIQ now does not rely on that service anymore.

  • WEBIQ-3801 License Agent: can be configured by a JSON file which will now be created by default (it was supported before, but not created if it did not exist)

  • WEBIQ-3819 Removed PnP DeviceID from licensing data to prevent licenses from becoming invalid when the firmware or driver is updated (specifically Windows)

WebIQ Designer

  • WEBIQ-3227 Fix: When updating to a newer version of WebIQ some dialogs inside the System dialog that had changed were not shown in the latest version because of caching
