IT updated a group policy that caused this issue. We resolved by going to Local Group Policy Editor > Local Computer Policy > Computer Configuration > Windows Settings> Security Settings > Local Policies > Security Options. Set "System Cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" to DISABLED

Post by mascara on TouchScreen does not work in Webvisualization. ^{CODESYS Forge talk (Post)}
I am configuring a Lenovo M900 computer with CODESYS Control RTE SL 3.5.20.30. I use an Aoc E2272pwut LED 21.5 monitor. The touchscreen works perfectly in the Windows 10 PRO environment but does not work in the WebVisualization environment (Window opened at PLC startup). Does anyone know if it is necessary to configure any drivers in Win RTE? I am at your disposal for any questions. Thank you.

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.

Post by darko7417 on When running as a service, CodesysControl doesn't write log files to the disk (and other CmpLog related issuess) ^{CODESYS Forge talk (Post)}
I run CODESYS runtime as a service and use CmpLog (the LogAdd2 function) to log different events to a file. I have done this many times before on various projects and hardware, and it works fine. On this particular system, I have CODESYS 3.5.20.40 running on a Windows 11 PC. The CODESYSControlService autostarts (with Local System credentials, the default), and the application runs fine. However, the configuration file is not read (or at least not the one that should be, or not the CmpLog section), and log files are not written to the disk. I would be thankful if anyone knew why this is happening and how to fix it. A note to CODESYS people: you must provide more information on the codesys configuration file, CODESYSControlService.exe and other major components and system behaviour. You created the service and various features (i.e. logging), but haven't explained how they work, which, in my opinion, is below standard for industrial automation software. These are my observations: - When running as a service, the config file is not read (none of them), or at least the CmpLog section is not read. I checked the log using Codesys IDE, and the CmpLog parameters are not the ones I have set in any of the config files. Which CmpLog config values does the service use, and where does it read them from? I have no idea, but it's not the config files. Here are the codesys config files I located on the PC's disk: o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControl.cfg (only 2 lines in this config) o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\AppDataFiles\CODESYSControlWinV3\CODESYSControl.cfg o C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\tempCFG\CODESYSControl.cfg - When I run codesys as an app (e.g. by clicking the icon), this config file is read C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg and log files are written ok. The icon target is "C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControlService.exe" -d o the -d option, I think, starts a cmd-like window showing service debug output (the output shown in log in the IDE) o the -i option, again I think, means install the service - I tried adding -d to service start parameters in the registry, but it started only once and after that it refused to start. Knowing what -d does and which other options are available would be great (e.g. can I make the service read a different config file). - Syslog UDP logging works fine in any case. - These are my CmpLog parameters ~~~ [CmpLog] Logger.0.Name=PlcLog3 Logger.0.Filter=0xFFFFFFFF Logger.0.Enable=1 Logger.0.MaxEntries=10003 Logger.0.MaxFileSize=50003 Logger.0.MaxFiles=33 Logger.0.Backend.0.ClassId=0x0000010B ;sends logger messages to SysOut Logger.0.Backend.1.ClassId=0x00000104 ;writes logger messages in a file Logger.0.Backend.2.ClassId=0x00000135 ;sends logger messages as UDP syslog Logger.0.Type=0x314 ;Set the timestamp to RTC ~~~
