IDS NXT cockpit 3.1

This version of the IDS NXT cockpit supports Windows 10 64-bit (version 22H2) and Windows 11 64-bit (version 22H2).

New and changed functions

Support of scalar variables (Single Part Results) for OPC UA.

General improvements

The transfer to the FTP client is no longer automatically deactivated if the connection is interrupted. Transmission errors are stored in the logbook. If the file transfer fails repeatedly, a system status message is displayed.

Classifier 3.1.0

Support of the new CNN file extension *.rcla. Neural networks trained in IDS lighthouse for OS version 3.1.0 receive the new file extensions.

CNN Evaluator 3.1.0

Support of the new CNN file extensions *.rdet and *.rcla. Neural networks trained in IDS lighthouse for OS version 3.1.0 receive the new file extensions.

Object Detector 3.1.0

Support of the new CNN file extension *.rdet. Neural networks trained in IDS lighthouse for OS version 3.1.0 receive the new file extensions.

OPC UA Server

3.1.1

An error prevented the OPC UA Server from being stopped. This error has been fixed and the OPC UA Server can now be stopped again in the IDS NXT cockpit via the "Server" slider.
An error could lead to a crash of the OPC UA Server vision app if a vision app on the camera transmitted an empty result after image acquisition. This error has been fixed.

3.1.0

Support for scalar variables (Single Part Results) for easier access to programmable logic controllers (PLCs).
Vision app information, results, configurables, actions and info elements are now available as nodes.
The result processing has been optimised.

IDS NXT Vision App Creator 3.1

The IDS NXT API has been updated to version 3.1.0 so that you can program vision apps for IDS NXT OS 3.1.0.

Known issues

IDS NXT cockpit	Upload backups	The maximum possible backup size is limited to the free RAM space of the camera at the time of upload.
IDS NXT cockpit	Number of maximum accesses limited to 3 per camera	A maximum of 3 users can access the same camera via IDS NXT cockpit at the same time. This also applies in the context of self-programmed applications.
IDS NXT cockpit	Vision app "Crawler" is no longer usable.	The separate vision app "Crawler" is no longer compatible with IDS NXT cockpit 2.3.0 or higher, as the Crawler application has been integrated into IDS NXT cockpit from version 2.3 on. If you are working with an IDS NXT cockpit version 2.3.0 or higher, uninstall the Vision App "Crawler" if it is still installed on the camera.
IDS NXT cockpit	Icon for Crawler is displayed 2x in IDS NXT cockpit.	If the vision app "Crawler" is still installed on the camera after an update to IDS NXT cockpit 2.3, the crawler icons are displayed 2x in the IDS NXT cockpit. Uninstall the previous vision app "Crawler" on the camera.
IDS NXT cockpit	Mixed operation of IDS NXT cockpit and IDS peak	In the case of mixed operation with IDS peak, uninstalling IDS peak or IDS NXT cockpit may lead to complications when updating the GUF files. After uninstalling, reinstall the remaining software to fix the problem.
IDS NXT cockpit	Vision apps and previous ROI feature (IDS NXT OS < 1.3.0)	If vision apps are still using the previous ROI feature, the ROI may show an incorrect position when switching binning.
IDS NXT cockpit	Multi camera viewer and vision app selection	If you have already selected a vision app for a camera in the multicamera viewer and you subsequently install a new vision app on this camera or delete a vision app, the vision app selection in the multicamera viewer is reset. Set up the vision apps on the camera. Configure the multi camera viewer. Select the vision app in the multi camera viewer.
IDS NXT cockpit	Maximum frame rate in freerun mode	To achieve the maximum frame rate in freerun mode, no images should be displayed with the IDS NXT cockpit due to performance reasons.
Vision apps	Vision app crashed	If a vision app has crashed, you have the following options to restart it: Open the IDS NXT cockpit and restart the vision app in the VApp Manager. When the camera is restarted, the vision app is automatically restarted. If the problem persists, contact the vision app developer.
Object Detector	Result output	Japanese characters cannot be displayed in the result image.
Classifier	Result output	Japanese characters cannot be displayed in the result image.
Classifier	Nets with attention maps	It was noticed that in certain cases classification results differ significantly, which is likely due to the different net architectures. If you use nets with attention maps, you may get different results compared to nets without attention maps. These differences occur because different net architectures are used for training. For serial application, we recommend to use nets without attention maps.
OPC UA Server	New installation of a vision app	After reinstalling a vision app, it may be necessary to call the "PrepareRecipe" method twice to enable the corresponding recipe. Alternatively, after reinstalling a vision app, it is recommended to start it once initially.
IDS NXT Vision App Creator	Update of the IDS NXT Vision App Creator	After an update, the setting of the alternative "Source Folder" for projects must be reset.
IDS NXT Vision App Creator	Update the virtual machine	During the update, the virtual machine is deleted and replaced by a new one. Before updating, you must manually back up files that you have stored in the previous virtual machine and want to use further.
IDS NXT Vision App Creator	Uninstallation	The installation of the IDS NXT Vision App Creator does not require administrator privileges. If you installed the previous version as an administrator, the uninstall entry in the Control Panel may not be removed automatically. Go to "Control Panel" → "Programs and Features" and uninstall the previous version of IDS NXT Vision App Creator here.
