The stepper supports CiA402 maybe I can use a CiA402 library to controll the stepper motor. Has anybody experience with that?

I don't know why the EtherCat fails, but what happens is: First I have only one 1WireMaster running on my Raspberry Pi and EtherCat is running fine. Then I'd like to add a 2nd 1WireMaster. Therefore I enable a 2nd GPIO Pin on the raspberry in the file "/boot/firmware/config.txt". dtoverlay=w1-gpio,gpiopin=4,pullup=0 dtoverlay=w1-gpio,gpiopin=23,pullup=0 To be able to use this 2nd 1WireMaster in Codesys Runtime I Adjust the CODESYScontrol.cfg file and add there: PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ After a reboot the EtherCat Master is not working any more. I didn't even add a 2nd OneWire Master in Codesys, but still if I do the EtherCat does not work. Do you have an idea why?

Could you check the taskcycle time in the taskmonitor (online monitor) - do you really see this 1s on Ethercat Task? Need to check this on my hardware but will take some time...

Hi everyone, I'm currently working on a project using Estun Pronet servo drives with EtherCAT communication, and I need the appropriate ESI (EtherCAT Slave Information) files to set up the network. The specific models I'm using are: Pronet-04AEG-EC Pronet-02AEG-EC-R1 Pronet-10AEG-EC-R1 Pronet-20AEG-EC-R1 Pronet-50DEA-EC-R1 If anyone has the ESI files for these models or knows where I can download them, I would greatly appreciate your help. Thank you in advance!

CODESYS Forge

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

Hi, a few suggestions on how to tackle the problem: - it might help to increase the cycle time of the ethercat task - increase the value of the ethercat parameter DCInSyncWindow (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/DCInSyncWindow.html) (see attached image) - enable FrameAtTaskStart (https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/pou-IoDrvEtherCAT/FrameAtTaskStart.html) in the ethercat master (see attached image) - if the drives can handle the synchronization problems, checking of the synchronization can be deactivated using SMC_Set_ETC_DCSyncSupervision (https://content.helpme-codesys.com/en/libs/SM3_Drive_ETC/Current/SMC_Set_ETC_DCSyncSupervision.html).

Didn't help. I'm just trying to understand why the errors occur. Are they from the poor driver or from the Linux network stack. That's why I wanted to know how the rxerros and lostframes are counted. Because in other places (like ethtool info) there are no any issues. And the Ethercat device works fine. And it also strange that on the second ethernet port with a different HW and driver Ethercat works better, but still time to time gets such errors.

Hello Edwin, Thank you foryour answer but, I believe I was not very clear in my question, sorry. What I wanted to know is if there is a generic EtherCAT slave object already in CODESYS that I can use for anything, remote IO, Drives, VFD's and so on, as long as I match PDO's. Is there such an object? Thank you again!

Hello, Without much info, I would assume that this is an optional object on the EtherCAT network and it's either disconnected or the address doesn't match. I would look into the devices manual or contact the manufacturer for further assistance. And, I would have posted a new topic instead of using a non related one... Cheers!

I was answering your last paragraph Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work).

Also. Every third (or so) attempt to login/compile is unsuccessful with the error prompt "one or more errors occurred", however there is no information available on what this error might be. If I remove the PersistenceManager-module, these problems are not present.

Post by egau on Hard shutdown: no code on device after power on
CODESYS Forge

This explanation aligns with the issues weβre experiencing with our machines. The scenario I described is happening with one of them (letβs call it Machine A). This machine is identical to another one (Machine B), except for some custom code that facilitates communication with an external Beckhoff PLC for MES integration in the production line. Machine B has been powered on and off daily for at least three months and has never had this problem. Given that, I highly doubt the MES custom code is the cause of the code corruption. This being said, your explanation does seem plausible. However, if faulty EtherCAT cables were the issue, why wouldn't the error occur during normal operation? Why would bad cables only cause problems during a hard shutdown? One last question: When you encountered this behavior, did you see a similar error in your logs? i.e, an "AccessViolation" exception in the EtherCAT Task?

Hello everybody I want to controll a stepper driver from Leadshine (EM3E-556E). The EtherCat slave is CiA 402 compatible. Because of this I bought the Softmotion Light Package from Codesys and implemented it in my project. I rightclicked the EtherCat slave and added the Softmotion Light axis. But now the error message shows: "The license is missing or invalid. The PLC runs in demo mode." What have i done wrong? I use Codesys 3.5.17. Is it possible that the stepper driver is not compatible with the Softmotion license? Thanks for all your help
