Post by durstloescher on Codesys Input Detector ^{CODESYS Forge talk (Post)}
Good morning, I am currently working on implementing a display dimmer. I want the display to dim after X minutes. This works so far. The implementation is done via the Linux subsystem, to which a command is sent to dim the display. However, my problem is resetting the timer when input is received. I want the dimming timer to be reset with each click/touch. Unfortunately, I can't find a suitable solution for this. Are there any ways to do this? Codesys v3.5 SP19 Patch 2

Post by peter-skokanek on Raspberry and problem with runtime ^{CODESYS Forge talk (Post)}
Hi, Similar problem, I have license for Raspberrypi Control MC SL. It didn't work with version 4.10.0.0. I have now instaled new version 4.11.0.0. Raspberrypi Control SL. The same behavior, runtime works sometime several minutes, sometime only several seconds. The second problem is with license. There isn't available any runtime MC SL on Codesys shop, not even older version 4.10.0.0. Is it only temporarily or, MC SL will be not available more for rpi?

Post by john-martin on Control SL Extension Package doubts ^{CODESYS Forge talk (Post)}
Hello everybody, I'm trying to understand the SL control extension package, more specifically, the external IODriver example, because C integration is very easy and I just made my first C component successfully. Ther External IODriver has no documentation and it's not clear how to proceed. Furthermore, there is no information on how to modify the device descriptor, which is necessary to import the device into the Codesys repository. Any advice ? Thank you in advance and best regards.

Post by nano on Is there any support for I2C on Raspberry Pi? ^{CODESYS Forge talk (Post)}
hello jdj this question can be answered well with a pretty good forge documentation: https://forge.codesys.com/drv/io-drivers/doc/Generic/ u r also able to create in codesys directly an iec-code by using the i2c-interface as driver using the codesys ide and st depending on the stepperdriver, used in yöur hat, its possible that an driver is already available in the device-repository. which mcp-device is used on the hat?

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
It's good that you've found a workaround. But it's bad that you need one. The array length auf my struct is 16. My struct also contains other arrays of structs. It contains a total of 1716 variables. I have tested saving and loading extensively under version 4.3.0.0. It looks good. I couldn’t find any problems. Maybe it helps to reinstall the update (see previous post). Otherwise you could try my test project (first post). This should work with version 4.3.0.0.

Post by bjarne-pagaard on WebVisu with Runtime Based User Management, Default user (no login) - is it possible? ^{CODESYS Forge talk (Post)}
Hi, With the new Runtime Based User Management, is there any way for WebVisu clients to be logged in to a default user automatically - no login prompt? I would like for the default user to be able to perform normal operation of the machine, without logging in to the WebVisu. This is possible with the Legacy User Management. For the Runtime based user management, there seems to be a default user for the TargetVisu - but not for the WebVisu. -Bjarne

Post by k4zz on Continuous Build Server ^{CODESYS Forge talk (Post)}
Hallo Martin, Thank you so much for the Code example. It works really fine for .porject Types. However, I encountered a challenge when attempting to apply it to .library Types. I also tried the option to "Perform static analysis automatically after compilation" # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code() Could you please offer any insights into why this might be occurring?

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Hi everyone, Had that problem before where I could not create another user but used the method just above and it worked great. My problem now is that I get this message when attempting to logon to the device: invalid user authentication on the target dev5, the new user created is pretty much a copy of the user 'Owner' except for the password. Any idea as to why I am always getting this "invalid user authetication on the target" message ? Using Codesys V3.5 SP19 Patch 6 + (64 bit) Regards

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Just adding some info regarding the issue above. Logged onto the project using dev3og5 user (see screenshots); appeared to be ok although when attempting to logon to the device message says 'currently not authorized to perform this operation on the device' (screenshot). If user dev3og5 has same permissions as Owner user; why would it not be authorized. I am at a loss; any assistance would greatly be appreciated. Thank you Mike

Post by andy-yemm on Assertion Failed ^{CODESYS Forge talk (Post)}
I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

Post by wind-11 on Problem with simulation Modbus ^{CODESYS Forge talk (Post)}
Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Post by mimodia1 on I do not have any reedings in RUN MODE from MPU6050........ ^{CODESYS Forge talk (Post)}
Good morning, mecke96. Exactly the same thing happens to me, although I have not done the part of executing a .py file. It only reads the temperature and the counter, but the other values are zero as in your image "no readings". I have tested the MPU6050 device on an Arduino and it works. Could you tell me if you solved it?

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello Vincent, I don't have 75 channels but it works for me as described above without any problems. There is also a parameter MAX_MODBUS_CHANNELS in the library parameters for the IoDrvModbusTCP module. The default value there is 100. Perhaps you are reaching the limit there? The value can be adjusted accordingly. I assume that this value is not accepted in the input dialogue and therefore the 'fixed' limit value 10 is used.

Post by rossanoparis on RevPi CONNECT+, CODESYS, EtherCAT master "Filedbus lost synchronicity" ^{CODESYS Forge talk (Post)}
Hello @rmaas I assume, you've already verified and tuned everything regarding the EtherCAT network. In my case the problem was due to a wrong core assignement. I suggest to not use the core #0 for your EtherCAT task. The OS realtime patch, which is present on RevPi OS, uses the core #0 for its porpouses and it mustn't be used by any other task which requires realtime and deterministic features. regards Rossano

Post by swe-hob on call of a method of a function block in another program ^{CODESYS Forge talk (Post)}
Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.
