Post by daanyouknow on Using a raspberry pi and NVLs to log variables outside of Codesys ^{CODESYS Forge talk (Post)}
Hi, My PLC/controller doesn't support OPC UA, so my current plan to create a ringbuffer/circular logger is to connect a raspberry pi to it, use the Network Variable List receiver and sender and raspberry pi codesys runtime to get the variables to the raspberry pi, after which I will use the pi which DOES support OPC UA to get the variables to a python program which logs the desired variables for a certain amount of time for me, would this work? I don't want to spend 50+ euros + licencing fees for a solution that might not work.

Hello, I'm asking for help with installing the license server for Linux SL 4.18.0.0. When I try to install it, I get a message that the WIBUCodeMeter package is missing. I checked the package manager tab to see if the package is installed, and it is - Codemeter 8.40.7120.501. I've checked the CodeMeter Runtime on the target machine, and everything seems to be working fine. One thing caught my eye: the Device Architecture tab says "None" Please help me solve this problem.

I want to cancel the automatic address allocation for all IO mappings. If I directly set the automatic_iec_address in class ScriptIoMapping to False, the address becomes None. So I reset manual_iec_address with itselfs value. It only work with the Input IOMapping . For output, it reports an error: "Invalid address: The channel type 'Output' requires address type '%Q'." I checked the description file ,both accessRight are total same. Does anyone know what causes this?

So here's how: I manually installed the following packages: codemeter-lite_8.30.6885.501_amd64.deb codesyslicenseserver_licenseserver_4.18.0.0_all.deb codesyswbmbase_wbmbase_4.18.0.0_all.deb codesyswbmlicensing_wbmlicensing_4.18.0.0_all.deb Of course, the license server appeared immediately. Trying to install it again using Install in the Deploy tab, the same error appears. Of course, the information that such a server is already installed is also there. Configuring PLC, S_PLC, EDGE, and SAFE_TIMER_PROVIDER went smoothly, and basically everything works. I wrote a simple program for S_PLC. I'm loading the programs into PLC and S_PLC. When loading the program into S_PLC, a message appears stating that there is no connection to the S_PLC controller. Timeout error. Restart the controller, attempt to load, and see the above. After changing the cycle time for S_PLC to 50ms, the problem no longer occurs. My question, besides the difficulty of installation for a new user, is what causes the cycle time for S_PLC to be so long, and how can I fix it?

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,

Is there a way to store persistent variables without a restart of codesyscontrol? Can anyone explain how and when CODESYS store persistent variables?

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.

I've created a TitleBar Visualization in which I have "Logo" on the Left corner, "Screen Name" in the center and Time/ date on the right corner. I've also created a 'Menu" visualization that slides out from left to right. I have TitleBar and Menu Visualizations in the MainScreen (3rd Visualization). I want to have "Screen Name" automatically updated on TitleBar Visualization based on Menu item selected from the "Menu" visualization. Can anyone advise how can I achive this? TIA

Hello, Basically, everything is clear to me. There's still the issue of a TimeProvider for an external device. This may be a stupid question, but I can't find this package. And of course, the question is, can the RPi machine be an external provider? Has anyone tested such a solution?

Hi, Im struggle with making custom button. The idea is simple grey light bulb after touch (input var) it changes to yellow but shows output var status not switch status. So if light is physically on, switched by physical switch, bulb is also yellow. How to do it?

Post by althafu on Codesys v 3.5 to factory IO ^{CODESYS Forge talk (Post)}
I have been following the steps shown in the RealPars video to connect CODESYS with Factory I/O. The connection works correctly when I use Ladder Diagram, but when I try the same simple input–output logic in Structured Text, the simulation does not behave as expected. Has anyone experienced this issue or knows what might be causing it?

As I see from your logs I think the Timeprovider is not accurate enough in your case. Things to check - at the moment you run it on the same device? (for tesing purpose ok) I would set 127.0.0.0 as IP and set it not really to Core 0 ( many other stuff is there)
