Post by mondinmr on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
In Windows I need create shared memory in PC software and connect from CODESYS. If shm is not GLOBAL doesn't work due different users between runtime and PC software. PC software need admin privileges. Name need "Global\\" before key. Very unsafe!!! If CODESYS create shared I cannot find key PC side. In Linux I can create shared memory as standard user, bind in the runtime docker, use keys without any "Global\\". Much more safe!!! If CODESYS create shared you need play with permissions to use app as standard user. I prefer create form PC software as standard user.

Post by mbmik on IoDrvModbusTCP_Diag not defined when using MODBUS ^{CODESYS Forge talk (Post)}
Hi Im trying to setup a Weidmüller WL2000 to run with MODBUS, to get some data from a server. Codesys V3.5 SP20. The issue is, that whenever i attach an ethernet port and add MODBUS Master und also a Slave, codesys will compile the project, but there always seem to be some remaining errors, which or only visible, when setting the messages window to "Pre-Compiled". I tried a lot of stuff to get rid of these errors, but cant find to seem the reason. New installation of codesys, cleaned project, setup completely empty new project, manually adding libs. Nothing helps. Any help is apreciated. Maybe we are doing something wrong.. Example Project is available, if somebodey wants to take a look. Greetings and thanks alot

Post by stewnguth on New License not working. ^{CODESYS Forge talk (Post)}
Hey there, I am pretty new to the codesys space, but I got a codesys control basic M license for my raspberry pi that isntalled with no problem yesterday. Today, I went to install the visualization M locense as well because I went over the variable limit and am getting a "servernotfound" error in codesys when attempting to activate. I also tried to follow the advice in some other threads and install using a license request file on the web interface but am getting a message saying "An internal error occured" when attempting to install the license. Can anyone help me get this up and running? Thanks for your time.

Good night. I am having a problem with CODESYS 3.5.11.40, which gives the exception EXCEPTION [ProcessorLoadWatchdog]. I followed some forum posts and tried to modify the CODESYSControl.cfg file, but it shows: [SysFile] Windows.WorkingDirectory=C:\ProgramData\CODESYS\CODESYSControlWinV3\D5050FE1 Then I go to this directory and try to modify CODESYSControl.cfg according to the forums, but it doesn’t work: [CmpSchedule] ;EnableLogger=0 ProcessorLoad.Maximum=80 ;Timeslicing.Mode=Internal ;Timeslicing.PlcSlicePercent=80 ;Timeslicing.PlcSliceUs=4000 ;Timeslicing.StartOnProcessorLoad=1 ;SchedulerPriority=5 ;SchedulerInterval=1000 I tried to change ProcessorLoad.Maximum to 0 or 100, but it doesn’t compile when I try. I really don’t know what to do,

The machine I'm currently using (Celeron J1900) already has the Kernel RT patch. I checked the performance according to the documentation. After running CyclicTest for 4 cores, the value for each core is around 6-7. I went through the entire process according to the documentation (I envy the TaskMonitor results in the documentation). The documentation states: "CODESYS Virtual Safe Time Provider The CODESYS Virtual Safe Time Provider is a standard interface that the user can use to transfer a second and external time base to the CODESYS Virtual Safe Control. The implementation is done as a client, which must run on another system with an independent time base." How do I implement this? I've been struggling for two weeks now - I'm too old to give up.

Post by imdatatas on Codesys IDE initialization error from a new Sandbox image ^{CODESYS Forge talk (Post)}
Hello everyone, I created a new sandbox image on the D drive with Codesys Installer. However, when I launch the IDE from this image, it gives the error shown in the attached image. -- Codesys V3.5 SP19 Patch7. -- The installer is the latest (2.5.0). -- All packages in the installer were updated to the latest version as of today when creating the sandbox. -- The originally installed IDE on the C drive does not give this error when launched. -- I last upgraded it to Softmotion 4.20.1.0 through the installer. Has anyone encountered the same or a similar issue? Will this issue be fixed in the next update? Best regards, Imdat

Post by timvh on Version management ^{CODESYS Forge talk (Post)}
This depends on what you want to achieve with installing the latest version and how you manage your projects and repositories. Maybe you also want to update your device (right click on it to update) or maybe your device is depending on certain versions of libraries (go to the library manager in your project and download the missing libraries). An option is also to first create a projectarchive of the current project you have before you install a new version of CODESYS. Then you can open this projectarchive in the new CODESYS version. Especially if you install the latest version of CODESYS in a Sandbox.

Post by gmau on Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired ^{CODESYS Forge talk (Post)}
Hello, I am writing to You with the problem of Profinet communication in my Codesys V2.5 SP21 project working on Codesys Control RTE V3 x64 device. I have implemented multiple Profinet devices in the network, the Profinet itself is configured properly, based on the hardware and software parameters of the industrial PC (Windows 10 IoT). My Profinet network contains such Profinet devices as a robot, IO-Link master with some devices on it, IO modules, safety, vision sensor (the configuration is attached to this topic). Once every few hours, sometimes more often, sometimes not even once a day, the error show up at one, two or a few random modules at the same time, every one is the same: "Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired". The communication is then lost with that module, but it is up instantly. It is not such a problem when it comes to regular IOs, but with safety or rotation table, it causes errors and machine stops. I have tried multiple solution based on any forum suggestions, manuals, etc., but it is still happening. Mabye when I turned on the Watchdog for this communication, it is happening less times, but still, I could not turning up the Watchdog parameters at the expense of cycle time of the process. The same is with Send Clock, Reduction and DHT. I have one of the ethernet port on the PC configured with CmpEt1000Drv driver. The card itself is Intel Ethernet Connection I219-LM. These devices are connected to one EKI-2728-NI-A Profinet switch (it was changed from the standard non Profinet one, but still nothing has changed). As I said ealier, I am attaching all the configurations for each device and the communication itself - if any of You had the same problems or have any ideas what could be the cause, I would be much gratefull for any help. For now I am out of ideas, if You have any additional question, please ask. Sincerely, PF
