It is not always a problem happens, but sometimes a rm takes a long time. I reduced the amount of calls to logi2c.py but I don't understand why TASK-i2c sometimes can cause problems for TASK-CAN

Post by garmusd on Raspberry Pi 5 GPIO not working. ^{CODESYS Forge talk (Post)}
I paid money for the RPi runtime because the Product Description says that GPIO is supported. It is also written in the Versions that since 4.11 RPi5 is supported. And I use 4.13. Nowhere is it mentioned that GPIO is still not supported... It's a pity that the Codesys developers still can't find a way to fix it. Are there plans for when it will be fixed or are the developers too weak? Just wondering, is there anyone with a working GPIO? Can you share the details of your system?

Hello, I currently have my trend configured with a maximum size limit of 5MB (additional settings can be seen in the attached image). However, I am encountering an error related to this trend, specifically within the TrendStorageAccess library. The device log shows the following message: TrendStorageAccess: prvCheckForSizeLimit (see the attached image for details). Does anyone know the reason for this error? Additionally, where can I find more information to troubleshoot this issue? Thanks in advance!

Post by winki on Modbus TCP & RTU with Control for Linux SL ^{CODESYS Forge talk (Post)}
For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.

Post by smartcoco on Request a dark mode for CODESYS ^{CODESYS Forge talk (Post)}
CODESYS IDE is not a modern IDE. Its interface is ugly, its operation is not user-friendly, its functions are lacking, its feedback is slow, and its development is not good enough. In fact, CODESYS is a helpless choice under the current situation. But this situation will not last long. For example, SIMATIC AX is a strong competitor of CODESYS, which is more open and inclusive.

Hi Trusty-Squire, just seen you post , thanks for the reply. I was out on site the other day as it had done it again and changed a few things like cycle time etc. plc load is only 7% at its highest. I took a few screenshots while i was there to add to this post. its been up for about a week now but seems to happen at random every couple of weeks. fingers crossed!

Post by dkugler on Beckhoff EL6652-0010 with Codesys ^{CODESYS Forge talk (Post)}
we use successful for many years the KEB MFI terminal for Profinet, EtherCAT, Ethernet/IP,... You'll need a EtherCAT Coupler as "head" from KEB, Kendrion or Berghof. It's all the same board inside: https://www.kebamerica.com/products/ethercat-bus-coupler/ Or the coupler with 16Di/Do integrated: https://www.kebamerica.com/products/ethercat-digital-io-module/ last year I got a EK1100 with EL6731 Profibus treminal runnig. But it was a lot of reverse engineering and thinkering in Codesys and TwinCAT to be done, to get it up, fulfilling my needs. Good luck!

Post by johnbomb on Ignore Dependencies When Loading Package? ^{CODESYS Forge talk (Post)}
I'm trying to load a .package into Codesys 3.5.21, but the package is intended to only work with Codesys 3.5.18.0 and is configured with dependencies on the specific versions of other packages included with 3.5.18.0, and 21 has newer versions so the package will not install. I would like to install the package anyway to try and get things working on a newer Codesys version, since for some reason the installer for .18 errors out and doesn't fully work in my environment, but .21 seems to work fine.

Hello, For my delta robot i wil use the MC_MoveCirvularAbslolute function. Every time that i set the execute of this function has my Axis group a error. Thats is: The dynamic limits for the movement are invalid. What can i do that this error go away? I saw a view funcitons with limit dymanics but i don't now how they work. If i use the function MC_MoveLinearAbsolute than i have no error. Does anyone know how i fix this?

In order to set the placeholder to empty, open the Library Manager and click on Placeholders in the Library Manager ribbon. If you left click in the library column for CmpEventMgr Implementation, it will show you the available library versions for CmpEventMgr Implementation. To update the runtime, open the Project menu and select Project Environment. That window will show you the current version of CmpUserMgr Implementation and if there is a newer version available in the Recommended column.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
An update note. Still using linux/Qemu. Still happy, but sometimes some things are harder. I lost the "bridge" connection to my VM (meaning for instance I couldnt "scan network" and find local units. Have spent tons of hours to find out why. Finally it seems the traffic got blocked by the firewall/iptables so needed to set rules for that. So friendly note that rules must allow forward traffic to/from you configured host bridge device.

Post by eschwellinger on Licensing info not available. ^{CODESYS Forge talk (Post)}
yes and no ... if you run the license server on the host (to serve licenses to the docker instances / vplcs then there is no runtime which could check the licenses on the host. Therefore you need the CODESYS WBM to activate or check the licenes or you could use in CODESYS IDE the licensemanager ( not the one for the device licenses) but you have the the IP of the license server that he know where to search for the licenses ..tool options i guess to add it, will add a screenshot later.

Hi imdatatas, sorry to hear this issue caused so much overhead for you. Frankly, I'd expect a project created with an older version to compile without errors after opening > it with the latest Codesys version and updating all libraries. Yes, that is a reasonable expectation. I tried a few times but could not reproduce the problem. In case you run into the problem again, we can investigate the issue if you send a project archive.

There seem to be problems with the latest version of raspberry pi os 64bit (I used the lite version). The codesys control runtime crashes after a few seconds. The same runtime works on the raspberry pi image from 2023-10-10 When starting the runtime from the commandline, i get the following error: ooops... this runtime was build for RASPBERRYPI. Hardware version or firmware version not supported! (and yes, I'm running this on a raspberry pi :-)

Hi, can you please provide a new example for the topic at CODESYS "Client Independent Visualization Switching" https://forge.codesys.com/prj/codesys-example/client-independ/home/Home/ Since a few versions, the functions used cause warning messages. Examples for the use of all function blocks from the Visu Utils would generally be very helpful!

Hi, I want to use Maxon IDX drives for some simple robotic applications. I have used Maxon's Epos for generating a DCF file to import in Codesys (attached). Then I can add the IDX motors under a CANopen manager in the device tree. Unfortunately, I cannot add a "softmotion axis" to the IDX motors. Now I am wondering, why? Without being able to attach a softmotion axis to the device in the device tree, the use of the motor is greatly reduced... spiessli

Post by andrej on POU - Access to runtime ^{CODESYS Forge talk (Post)}
Hello all, when creating a POU, the Codesys IDE allows the setting "Enable System Call" (in the Settings, Property -> Build), see picture. The name suggest, that runtime functionalities i.e. functions of codesyscontrol such as "stop plc" etc. can be directly called. I tried various approches without success, the following does, unsurprisingly not work. FUNCTION accessRTE: BOOL; ****************************** codesyscontrol.stop(); Can you please tell me how I can make a system call to codesyscontrol from a POU. Or could you provide me with a use case for this setting. Many thanks for your feedback and kind regards Andrej

Post by gseidel on Scara3 kinematic robot error ^{CODESYS Forge talk (Post)}
Hi aniket-b, this error has nothing to do with the scara3 kinematics, or robotics, or SoftMotion. It means that the EtherCAT bus is not synchronized. The usual cause is that the realtime of the PLC is not sufficient. See https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html for details and ways to solve the problem. You can also check the PLC log for additional information about the error. Best regards, Georg

Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Post by rcaponi on Codesys Control RTE V3. Remote Control ^{CODESYS Forge talk (Post)}
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi
