Post by dasch on eCockpit - unable to start simulation ^{CODESYS Forge talk (Post)}
This is a known bug in e!Cockpit. See Release notes of V 1.11: 1 e!Cockpit Release Version 1.11 (2022-07) ATTENTION: If a library that uses asynchronous tasks (e.g. WagoAppConfigTool, WagoAppCloud or function modules such as Dali-Master) is dragged into the project, the simulation cannot be started. It is already sufficient to add the library to the project (an FB does not even have to be instantiated). I guess you are using one of these libraries/modules in your project. We e.G. often use PWM modules, these are also affected.

Post by ggarcia94 on IMAGE DISPLAY ACCORDING TO INPUT VARIABLE ^{CODESYS Forge talk (Post)}
Reopening this thread as I need to make a few images visible depending on the value of a variable. However, in the properties of the image I do not have the option to make the image visible (see attached image). I´m using Codesys V3.5 SP19. However, when I use V3.5 SP17 I have the option to make the images visible. Can someone help me achieve this with V3.5 SP19? EDIT: Fixed. Just had to uncheck Support client animations in the Visualization manger settings

Post by mondinmr on Jitter problems on imx8 ^{CODESYS Forge talk (Post)}
SOLVED!!! In this imx8 max_cstate=1 in kernel boot parameters is not working! We found a workaround: #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <stdint.h> int main(void) { int fd; uint32_t value = 0; fd = open("/dev/cpu_dma_latency", O_WRONLY); if (fd < 0) { perror("Error opening /dev/cpu_dma_latency"); return 1; } if (write(fd, &value, sizeof(value)) != sizeof(value)) { perror("Error writing to /dev/cpu_dma_latency"); close(fd); return 1; } while (1) { pause(); } } This simple code launched before CODESYS do the same work! Now jitter is identical as measured by cyclictest!

Post by rcaponi on Codesys 3.5 SP19 Patch 4. Trace context menu does not work ^{CODESYS Forge talk (Post)}
Hello, I'm using the new Codesys 3.5 SP19 Patch 4 version with CODESYS Control for Raspberry Pi MC SL v4.8. Compared to the Codesys 3.5 SP19 Patch 1 version, the context menu on a Trace object no longer works. So I can no longer run the Downloader Trace command. Do any options need to be enabled with the new version? Best regards Roberto Caponi

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 nikgind on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi, yes i did solve it. You have to change the namespace 0 model in the UaModeler. Open the modeler --> Settings --> Edit Settings --> scroll down to the last option "External Model Support" --> Check "Allow replacing built-in..." Now create a new project in the UaModeler. If you have to choose your base models, you can see the option "Find another Opc.Ua.NodeSet2". I have attached the .xml i am using.

Post by vamsi on How to configure gateway for programming RPi 2B using Codesys ^{CODESYS Forge talk (Post)}
I found out what I was doing wrong. I was entering the wrong IP in the gateway. I found that I have to enter the RPi's IP in the gateway field from this post https://forge.codesys.com/forge/talk/Runtime/thread/01703ca970/#d9f6 But I do not understand why it has to be the RPi's IP. Could anyone help me in clarifying this?

Post by aliazzz on Unable to deploy Virtual Control SL on ARM64 (Raspberry Pi5) ^{CODESYS Forge talk (Post)}
An interesting remark for CODESYS Support. I found this after looking through the Runtime Deploy Tool messages when I connect to an AMD64 architecture Successfully Connected to Target ( {MyIP} - AMD64 ) when I connect to an ARM64 architecture (Raspberry Pi5) Successfully Connected to Target ( {MyIP} - ) As clearly seen in the attached .png, the AMD64 target is detected, while the ARM64 target architecture is not detected (displayed). I assume that this is the reason why the pulldown menu isn't populated correctly.

Thanks for the reply, i am using codesys SP16 patch 5 as this is the version that is compatible with my IFM controller. i am accessing the lastusage variable from the VisuStructClientData structure through a pointer. when i log in it lists the time since last log in but does not continually count, it remains a static value which isnt useful. hopefully you can help. Thankyou

Post by paulpotat on cm4 runtime problem ^{CODESYS Forge talk (Post)}
It looks like it works with 4.13.0.0 indeed. However when installing the runtime, it's not possible to select the multicore option (see attachment). But once the 4.13.0.0 runtime is installed, the logs seems to indicate that the runtime is running in multicore mode. Looking at "htop" output, it seems like it actually is running on multiple CPU. This is very misleading, is it normal or is this a bug ? Thank you for your answer @eschwellinger, BR

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Ah - forgot another question as it may be related to the PLL problem: I am executing a 4ms cycle. I do not call (from what I know) the Ethercat_MAster periodically in my program. The bus cycle task is set to the Ethercat task. I would assume that the master should send 250 frames per second. Yet, the status of the master says it transmits 500 frames per second which would indicate that the master is called twice. Any ideas there?

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 winki on Modbus TCP Client ^{CODESYS Forge talk (Post)}
Hello, I am new on CODESYS env. I would like to do some Modbus TCP, but I am wondering If using codesys you must use the device "Modbus_TCP_Client" & "Modbus_TCP_Server". I would like to do it without device, only using ST. Is that possible ? I try the example : MODBUS_master_example, but it is not working. If it is possible to dot it without any Device I will show my code. Thx a lot

Post by micik on PLCOpenXML Export/Import with Visualisation ^{CODESYS Forge talk (Post)}
I have noticed that Codesys doesn't provide option to Export any Visualization objects even though there is option to check to export VISU_TASK, which is strange because when Import in another empty project, user will end up with build errors. I understand that probable reason for this is that PLCOpenXML specification includes only "PLC" parts of the project (POU, PRG, variable lists, device ....), but not sure about it. Perhaps, there is some option to include visu objects also in the plcopen xml export list??

Is it possible to use MC_Home without enabling the drive (MC_Power)? On the drive the homing method 35 (Homing on current position) has to be executed. The drive has to stay disabled due to safety. This is explicitly allowed by the drive. Unfortunately MC_Home reports the error SMC_REGULATOR_OR_START_NOT_SET when executed. Are there other options to start homing, if not with MC_Home?
