The SICK AppEngine software product integrates devices such as industrial PCs or controllers into the SICK AppSpace eco-system and makes them programmable. The SICK AppEngine thus expands the portfolio of programmable devices on which SICK AppSpace can be used. With the aid of the eco-system, sensor applications are implemented and executed on the SICK AppEngine. The SICK AppEngine contains a collection of powerful software libraries and provides application developers with numerous functions via a uniform API structure.
This document pertains to the software SICK AppEngine 1.7.0. It contains new features, minor improvements, and fixes since its previous version and remaining known limitations and issues.

Description
Workaround
ARM64 ARM32 Windows x64 Linux x64
Timer API precision
Precision of the Timer API in SICK AppEngine is limited by the precision of the system timer of the operating system. Timer precision depends heavily on the general system load of the host hardware (SAE-95).
Please make sure that your application handles these precision limitations.
ARM64 ARM32 Windows x64 Linux x64
Ethernet interfaces limited to 8
The number of Ethernet interfaces that can be accessed by SICK AppEngine is limited to 8 Ethernet adapters of the host hardware on which SICK AppEngine is running. SICK AppEngine scans for Ethernet interfaces during installation and uses the first 8 adapters (SAE-91).
If your host hardware offers more than 8 Ethernet interfaces, please reduce the numbers of network adapters to max. 8, so that all adapters can be used by SICK AppEngine.
ARM64 ARM32 Windows x64 Linux x64
Auto IP scan shows IP address 0.0.0.0
When automatically searching for SICK AppEngine on certain host hardware using the SICK tools AppManager, AppStudio or SOPAS ET, sometimes the IP address 0.0.0.0 shows up (SAE-67).
Please use SICK AppEngine under the IP address 127.0.0.1 or the IP address of the respective host hardware instead.
ARM64 ARM32 Windows x64 Linux x64
Auto IP scan cannot find SICK AppEngine sporadically
Sometimes, SICK AppStudio and SICK AppManager are not able to find the running SICK AppEngine when using the automatic IP address scan, since the UDP scan is getting lost.
Please uncheck the automatic IP scan and only use the custom IP address configuration by adding the IP address of the host hardware of SICK AppEngine to the list to ensure that SICK AppManager and SICK AppStudio will find SICK AppEngine on the host hardware.
ARM64 ARM32 Windows x64 Linux x64
Copy protection mechanism
Copy protection mechanism for SensorApps in SICK AppSpace is not supported by SICK AppEngine. This means that it is not possible to install copy protected Apps so that they are still available after restart of SICK AppEngine. For development of new SensorApps, the copy-protection mechanism is deprecated in SICK AppEngine.
For copy-protection of SensorApps on SICK AppEngine, a licensing mechanism is offered. Please refer to the documentation of the Licensing API to protect your Apps.
ARM64 ARM32 Windows x64 Linux x64
Multi-Engine is not yet supported
The application of running multiple instances of SICK AppEngine on the same host hardware is not supported yet.
Please get in touch with SICK to clarify your request.
ARM64 ARM32 Windows x64 Linux x64
Access to external drives
For usage within SensorApps, SICK AppEngine provides access to the file system of the host hardware via its APIs. By using the File API, AppEngine has access to the user's directory under C:\Users\<user>\AppData\Local\SICK\SICK AppEngine, but cannot access other directories or external drives such as USB drives (SAE-104).
Access to additional drives is possible with SICK AppEngine build-to-order on request only. Please get in touch with SICK to clarify your request.
ARM64 ARM32 Windows x64 Linux x64
Warnings at SICK AppEngine startup
During startup of SICK AppEngine, there are still some warnings: Could not write udhcpc script (SAE-128)
The warnings will be resolved in the next release version of SICK AppEngine x86-64 for Linux.
ARM64 ARM32 Windows x64 Linux x64
Licensing
Licensing via CodeMeter runtime fails when system time of the host hardware is before 1.1.2000 (SAE-336)
Please set the correct system time on your host hardware.
ARM64 ARM32 Windows x64 Linux x64
App sorting
Usually, for AppSpace devices apps are ordered in an alphabetical order. For SAE the order differs with the effect that the default msdd that is shown when opening the IP address in the browser might be different (SAE-300)
We do not recommend relying on alphabetical order, instead, please make use of the following parameter to define the default webpage: Parameters.set("AEDefaultWebpage", _APPNAME)
ARM64 ARM32 Windows x64 Linux x64
Warning: API.Parameters.Node
Warning: API.Parameters.Node. Parameters CROWN won't be able to handle BigInt values
This warning can be ignored, SICK AppEngine is working as expected.
Windows x64 Linux x64
No support for GigE-Vision 2D cameras
SICK AppEngine itself does not support GigE-Vision 2D cameras
Use a third party GigE-Vision 2D driver like Halcon (3D drivers are included!)
Windows x64 Linux x64
AppEngine works with max. 2 GigE Vision cams
AppEngine may crash in applications with more than 2 GigE Vision-based cameras when applied inappropriately, like picoCam2 or midiCam2 (SAE-318)
Only use SICK AppEngine in applications with max. 2 cameras. Will be fixed in one of the next versions soon.
Linux x64
Error on memory consumption
SICK AppEngine is continuously observing the available memory on your host hardware. If you get the following message on the console window "Garbage collector called because system is going to get out of memory (>90% memory usage)! Please investigate.", this might happen, if the overall system load is high.
Please investigate the memory consumption of all applications running on the host hardware. Usually, the resource utilization is not caused by the SICK AppEngine and the associated Apps, rather as there are a lot of applications running in parallel on the same host hardware.
Linux x64 (legacy only)
Library dependencies issues
Dependence issues during installation depending on operating system and already installed library versions.
The script usually returns and error with the missing dependencies.
With online access please install them with your favorite package manager (e.g. "sudo apt install -f"). Without online access use an online device to search and transfer the package to your offline device (e.g. search on the official debian.org package search: https://www.debian.org/distrib/packages#search_packages).
More information on already known dependence issues can be found in the "Known issues" section in the SICK AppEngine (x64) - Getting Started.
Linux x64 (legacy only)
CodeMeter service is not starting during SICK AppEngine installation ("Wait for CodeMeter service")
Depending on the library versions on your operating system, it is possible that the CodeMeter service will not start during the SICK AppEngine installation.
CodeMeter depends on libxcb-xinerama0 which is probably missing on your operating system.
With online access please install them with your favorite package manager (e.g. "sudo apt install libxcb-xinerama0"). Without online access use an online device to search and transfer the package to your offline device (e.g. search on the official debian.org package search: https://www.debian.org/distrib/packages#search_packages).
Afterwards CodeMeter should be removed completely: "sudo dpkg --purge --force-remove-reinstreq CodeMeter" And SICK AppEngine installation script started again "sudo ./install-linux.sh"
More information can also be found in the "Known issues" section in the SICK AppEngine (x64) - Getting Started.
