Post by martinlithlith on Relay board / relays for raspberry pi 3 b+ ^{CODESYS Forge talk (Post)}
hi! im planning a project on a raspberry with Codesys. For this I'll need a number of relays to control heating and fans, all a max of 24v and about 2a. How would i know if the board / relays i buy will be working with Codesys? Does every hat work or does it need a library/driver? is there a list of drivers/libraries created? as this is a hobby project all tips on a relay board or single boards that works with codesys and not to expensive are very welcome.

Post by transmin01 on CANbus issue ^{CODESYS Forge talk (Post)}
Update: This initial issue was when using a Linux target PLC. Since then I have created a Win10 target PC and the Codesys software reported an issue associated with the device version (see attached). I am assuming this is an incompatibility with the xml file from the manufacturer and the firmware version on the module and I am chasing this up with Beckhoff. Question is, why would this not report with a Linux target?

On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

Post by martinlithlith on Raspberry Pi: List of available drivers / libraries ^{CODESYS Forge talk (Post)}
As most of the posts are moved here around 2015, what would be the right version of codesys to run? Would it be better to install a older version of codesys or should i keep on downgrading libraries? Is there any work done to update theses libraries? It´s been a few years since the last update in this post, are there new libraries/devices for raspberry being added/posted somewhere else? Thanks, Martin

Post by john-martin on Send file from codesys to...... ftp, cloud, etc ^{CODESYS Forge talk (Post)}
Hi everybody, I am looking for a solution to send files, for example, to an ftp or a cloud. I can't use oscat library because 64 bit controller are not supported. Therefore, I see that the IIoT library has some functions that might help me to implement this sending process in codesys. Does anyone have any examples of how to do this? I have spent some days with this issue without success. Best regards.

Post by timvh on Management of a PLC network from a remote station ^{CODESYS Forge talk (Post)}
Maybe the CODESYS HMI is a good solution. https://store.codesys.com/en/codesys-hmi-sl-bundle.html Run this on the remote main control station. In the HMI application you can add the data source manager and to this manager you can add Data sources. A data source has a reference to the PLC you want to connect to and can get access to the variables of the PLC application. You can then use these variables in the visualization of the HMI application.

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

@eschwellinger do you have any examples of using a USB barcode scanner? I have read through the forums here and I am unable to find how to get the barcode data to populate in a text field without having to first click into the text field to activate it. Is there a library that allows you to access the barcode data? I am really new to this in general any help is greatly appreciated, hopefully you have a pretty clear example

Post by andrax on Stop Programm geladen Ausnahmefehler ^{CODESYS Forge talk (Post)}
Hallo, ich habe seid neustem ebenfalls dieses Problem auf den Raspberry. Codesys 3.5.18 Nach dem Download geht die SPS in STOP und es blinkt schwerer Ausnahmefehler. Der Fehler kommt sporadisch und ist nicht reproduzierbar. Es passiert beim kompletten Download, aber auch bei Änderungen. Wie kann ich den Fehler eingrenzen? Nachtrag: Wenn der Fehler kommt, ist die Runtime auf dem Raspberry nicht mehr ansprechbar. Der Raspberry selbst schon. Für einen neuen Download muss ich den Raspberry neu starten. Das selbe ist auch in der Programmierumgebung, die Software hängt sich auf.

Hey all CODESYS-experts. I'm at a customer site, and we hade a power-failure and one of the devices apparently runs codesys and has crashed. It's an old device (out of warranty) that is bought many years ago. Now this device doesn't seem to boot. Any idea what to do in this case? We have access to the drive so we have access to the files. See screenshots.

Post by timvh on IFM CR711S Version Mismatch ^{CODESYS Forge talk (Post)}
You should ask IFM to provide you with the correct version of their controller packages. Then after you have installed this, you can select the correct version of the controller by right clicking on it in the device tree, update device, enable the option "Display all versions" and then select the version which matches your controller. Alternatively you can ask IFM to provide an update package which can update the runtime version on your controller to 3.2.0.0.

Post by marcolim on RPC failed 0x16c9a085 ^{CODESYS Forge talk (Post)}
Hello Matteo, I think the problem is about configuration of firewall (windows firewall usually). You can disable temporary the firewall to check if the communication works. Eventually you can: Go to the control panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change the settings. Scroll down in the application list to CODESYS and CODESYS ControlService. If you don’t see this application add it to the list. Make sure that all the checkboxes are checked (Domain, Private and public).

Good morning. I'm working with a Weidmuller controller using Codesys. My project use OPC-UA to communicate an application in my pc with the controller. Yesterday, I installed the license of the controller and test it, and the communication works perfect. I use the communication with anonymous login, and works fine. But, hours later, the anonymous login don't work, and the controller only allows connection via OPC with username and password. Someone know why this happend? Thanks

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

I'm using version 3.5.13. Is it possible to handle Recipe Manager in PRG in this environment? Can you give me a simple example? Although it has been confirmed that the functions work on Recipe Manager, they do not work properly when implemented through FB within a simple PRG. I would like to save the current value as a recipe or load the recipe's value as the current value. And I want to save the recipe as a file or load the recipe saved as a file. somebody help me. (TT)

there is a new problem with latest bootloader version. The problem seems to be: Version from2024-04-20 does not work-> 2024-01-15 version works the workaround is a rollback to January version: cp /lib/firmware/raspberrypi/bootloader-2712/stable/pieeprom-2024-01-15.bin ./pieeprom.bin rpi-eeprom-config pieeprom.bin > bootconf.txt rpi-eeprom-config --out pieeprom-new.bin --config bootconf.txt pieeprom.bin sudo rpi-eeprom-update -d -f ./pieeprom-new.bin sudo reboot

Post by micik on CAA File, how to check whether file exists or not ^{CODESYS Forge talk (Post)}
Hello, what would be the most efficient way to check whether the file exists or not. I don't want to use file.Open function, it seems like rather inefficiet operaton. I considered GetAttribute function, but this function doesn't accept filename (with path) as an input. Basically I need to check first time when program is loaded to the runtime i.e. when application is started for the first time, whether a file exists on the specific location or not.

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.

OK, I got this to work as shown above in mos89p's comment. What I did: Tools/Update Raspberry Pi. Reloading the runtime seems to have solved the web problem. I can view the visualization on the Pi and laptop using a browser as shown above. Thanks! But Isn't the visualization supposed to take over the screen of the Raspi? When I run visu projects on Windows or Wago, the visualization shows on that device's screen by default.. But this is not happening in this case
