I'm having right now trouble if the NVL is 'big' and I've needed to reduce the size. It sends for (about) 1 hour then stops.

...hört sich für mich eher nach Hardware problemen an, kann mich auch teuschen. Würde immer ins "SPSLog" schauen - vielleicht gibt da noch mehr info auch für den Fall das die Runtime nicht hochläuft.

Thank you for your answer. I did install certificates, especially for OPC UA Client/Server tests. This OPC UA PubSub test uses pre-shared keys, not certificates. By the way, I do you 3.5.22 patch 2.

Interesting. In the SMC_LimitDynamics case, do you reduce the maximum velocity of the SMC_GeoInfo based on the third derivative of the spline?

yes, you need to install Control RTE CX. In that package there is the Internal EthercatMaster / EthercatMasterSoftmotion which you could add then.

I installed Linux ARM SL and it recognizes the RJ45 ethernet ports, but I cannot get it to recognize the internal port for the IO cards.

Post by megasilver on Cannot download program to CR1074 – Version mismatch error ^{CODESYS Forge talk (Post)}
Hello, I am having a problem downloading my application to an ifm CR1074 using CODESYS. When I try to download the program to the controller, I get the following errors: [FATAL ERROR] Version mismatch at: 'KEYBOARD_SET_MAPPING' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 [FATAL ERROR] Version mismatch at: 'SYSCFG_SPLASH_SET_SPLASH_SCREEN_VISIBLE' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 [FATAL ERROR] Version mismatch at: 'SYSTEM_IO_BACKLIGHT_SET_CURRENT_BACKLIGHT_BLOCKING' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 [FATAL ERROR] Version mismatch at: 'SYSTEM_IO_BACKLIGHT_SET_CURRENT_BACKLIGHT' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 [FATAL ERROR] Version mismatch at: 'KEYBOARD_RESET_LEDS_BLOCKING' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 [FATAL ERROR] Version mismatch at: 'KEYBOARD_SET_LED_COLOR' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 [FATAL ERROR] Version mismatch at: 'SYSCFG_DEVINFO_GET_KEYBOARDS_INFO' Requested version: 2.0.0.12 Implemented version: 3.4.0.0 The controller is running an OS version that should be compatible with CODESYS 3.5 SP16, and I am using the latest available ifm/ecomatDisplay package for this OS version. Therefore, I do not think this is simply a CODESYS or OS compatibility issue. It looks like the application expects system functions with version 2.0.0.12, while the controller implements version 3.4.0.0. Could this be caused by an incorrect or outdated library, device description, package installation, or a mismatch between the libraries used in the project and the libraries installed on the CR1074? What would be the correct way to identify which component is requesting version 2.0.0.12 and how can I resolve this version mismatch? Thank you for your help.

Did you check the communication with a sniffer ? (ex. Wireshark) to check if the holding get to zero by a wrong writing (client initialization?) o something else?

For the DynamicText error i have finally found a solution. You have to delete some libraries from your project. For me it was the WagoSysIcon library which wanted to reference dynamictexts even though i didn't have any in my project.

Post by nickpoon on SysProcessCreate stopped working after SP21? ^{CODESYS Forge talk (Post)}
I'm going through the process of updating the CODESYS Project a machine to 3.5 SP21 (old version was 3.5 SP20). One function that stopped working when upgrading was SysProcessCreate. I need to run a .exe file that is located in C:\Program Files\MQTTStream. Some initial searching suggested that there are new security rules that prevent the SoftPLC from reading/writing files to outside of its Device folder (located here - C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\24FD6770) Relocating files helped fix my JSON file reader/writer functions (which were failing previously), but not the case for SysProcessCreate. I've even attempted to just run window's cmd.exe and with: pszCommandLine = 'cd /d C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\24FD6770\PlcLogic\MQTTStream & sift-proxy.exe --grpc_uri="https://grpc-api.siftstack.com" --api_key="xxxxxxxxxxxxxxxxxxx" mqtt-client --broker_ip=10.0.10.101 --broker_port=1883 --config_file="mqtt_telemetry_config.json" --username Plantd --password 1234 --stream_metrics --storage_path="sift-proxy-logs"' I have not been able to find a lot of documentation on this, and I suspect the new update may have created a bug for SysProcessCreate. Any help would be greatly appreciated
