Hi all, is there some library for Codesys to handle predictive models (MPC) such as https://www.mathworks.com/help/mpc/gs/what-is-mpc.html https://en.wikipedia.org/wiki/Model_predictive_control
/var/opt/codesys/PlcLogic not work here, again FILE_OPERATION_DENIED. May I simply moved my files in /var/opt/codesys/PlcLogic or need some particular settings?
/var/opt/codesys/PlcLogic not work here, again FILE_OPERATION_DENIED. May I jyst move my files in /var/opt/codesys/PlcLogic or need some particular settings?
By using the CAA FILE library (FB FILE.Open) (raspberry pi, codesys 3.5.19.0) I always get the error FILE_OPERATION_DENIED The file exist, it has r/w/x access and path is correct... Some idea to fix it?
some help?
I'm trying to add a canbus interface to my project (codesys 3.5.16.50) , but I get the error "Identifier 'CANbusDevice.CanbusDiag' not defined" . The library CANbus is properly add to the project. How to fix it?

I think the only way to readuce CPU load is slow-down task execution (orr of course get a bigger CPU). In your case take care to CPU load average, it's pretty high (more than 5, should be <0.65)

Is there some way to protect a POU with password in Codesys 2.3? I've tried with "user group" but seems not working well
I'm using Codesys 3.5.18 , is it possbile to define the Uinid ID in MOdbus TCP server?
Hi all, in my PFC200 Wago (750-8212) ,from time to time, I get following popup during download: When it appears, download is not possbile anymore: I need to "Reset all" the download the entire project. Did it happen to someone? any idea about to solve it? Thnaks for suggestions

After updating from 3.5.17.0 to 3.5.17.3 , every time I open the project i I get this addons are updated, what am I missing?
I'll try, thanks
that's strange,project has been saved with same Codesys version (3.5.16 patch 5), other causes?
I have a small project saved as library (3.5.16 patch5). If I try to save it as Compiled library I get this popup: What does it means? how to fix it?
Hi all, I have a rpi licensed (SL) actually running. Can I "backup" the license (transfer it out on rpi)? I need to format SD card , install new version of Raspberry pi OS and then I0d like to get back my license running. Is there some guide? is it feasible? BR
no way to run Codesys runtime with Bullseye.. Only restoring a previous SD card image (October, Buster) everything come back to work. Is the Bullseye the issue or because I update from Buster?
I have same issue.. not able to detect rpi by scanning after updating raspberry pi os.. this is what I see (moreover I have license but it seems to be in demo mode!!)

Do any of you use / used the Codesys redundancy package? Some feedback about its performance and limits? Thanks in advance

By saving a project as compiled library I get this error in latest Codesys release.. But I cannot find the library documentation package in Codesys store, where retrieve it?
Is there some way to perform an alarms ACK (All visible alarms) from logic (PLC_PRG) in stead of from Visual push button?
an example is pretty huge...and it'll referred to a specific file. In terms of concept you had to: 1-open the csv file (FILE.Open FB) --> get header of file (file.CAA.HANDLE) 2-using the header you read the 1st row (FILE.Read FB) https://help.codesys.com/webapp/VIPLMVOpanJfjqQXFKWGQlzGjxw%2FOpen;product=CAA%20File;version=3.5.17.0 3-you have to update the header to the last character read (File.GetPos --> File.SetPos) 4-read the 2nd row (FILE.Read FB) ...... x - close the file (FILE.Close) I suggest...
It works! thanks
I'll try, thanks for suggestion
for sure I have more than 80 characters..but string seems contains, just visualization area is not enough..
Maybe it's a stupid question, but I cannot find a way to wrap a text in a %s text field. If the connect variable (string) value is pretty big I see for cut text on webvisu
Thanks!
is there a way to change from a visualization to another using PLC code in stand of video push button?
Hi all, I'm trying to run a COM.Open FB in a Codesys 3.5 runtime of a Linux Embedded Device (Topcon OpusA3). I've got a look at serial sample on 3S website, but if I run the COM.Open I always get ERROR_UNKNOWN. Every suggestion is highly appreciated!
nevermind..after some reboot and apt-get autoclean CPU load moved to usual values
I've just migrating from Codesys 2.3 to 3.5 for programming Epec devices over CAn interface (Kvaser usb/can adapter). With 2.3 I've just set communication So, how get it with 3.5?
After updating the RPI runtime from 3.5.16.20 to 4.0.0.0 I get an high CPU load (>50%). Before updating it was just 3~5%,. Is it normal?

Hi Ingo, thanks for clarification. Do you know some function to read the "total" CPU load? (to get same value as in htop?)
I'm testing the call udiProzessorLoad:=SchedGetProcessorLoad(Result); but the CPU load I get is very different from "htop" value (In codesys I read 8, in htop I get less than 4%).. Why?

I've got again the popup.. did someone get something like this?
I've made a small application with raspberry and runtime v.3.5.14.40 with logic + Webvisu. Once a day or two, I've got crash of runtime as this: and I get description " [INFORMATION] A core dump created on the 05-Apr-20 08:55:55 for the application 'Application' is available on the device. " this is what I see on log
