Post by imdatatas on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, I have experienced such situations with some servo drive devices in the past. The home completion information is reported to the upper controller by the slave drive with the states of the relevant bits in the StatusWord (for example; 6041h Bit10, Bit12 in Home mode). If the states of these bits are correct in terms of number and state but the motor does not actually perform the action; You can contact the slave drive manufacturer. There may be a problem with the device firmware. Another area you can play around with is looking at the settings in the "Advanced configuration" for Softmotion axis on the page the link to below, and trying it out and using the one that works for you. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cmd_add_softmotion_cia402_axis.html A method I recommended worked for a user as in below message. https://forge.codesys.com/forge/talk/Engineering/thread/40bc82454d/ I hope your problem will be solved as soon as possible and by sharing the result here, you will help others to know and overcome it. Good luck. Best regards, Imdat

Post by thommy54 on Raspi-Cam: CameraStream.project nicht zum Laufen zu bringen ^{CODESYS Forge talk (Post)}
Hallo, Ich bringe das CameraStream.project nicht zum Laufen. Ich sehe die Ursache darin, das das Beispielprogramm sehr sparsam mit Programm-Kommentaren umgeht (von der Hilfe gar nicht zu reden). Ich habe beide Varianten bei der zu ändernden Zielvariable getestet: //copy video.htm to the webserver; //the location of the webserver depends on the used Apache version as mentioned in online help hDirHtmlTest:=SysDirOpen( szDir:='/var/www', pDirInfo:= ADR(dirInfo), diMaxDirEntry:=iMaxDirEntry, szDirEntry:=szDirEntry, pResult:=ADR(iDirHtmlError)); IF (iDirHtmlError = 0) THEN SysDirClose(hDir:=hDirHtmlTest); SysFileCopy('/var/www/video.htm', '$$PlcLogic$$/Application/video.htm', ADR(dwCopySize)); ELSE .... als auch hDirHtmlTest:=SysDirOpen( szDir:='/var/www/html', pDirInfo:= ADR(dirInfo), diMaxDirEntry:=iMaxDirEntry, szDirEntry:=szDirEntry, pResult:=ADR(iDirHtmlError)); IF (iDirHtmlError = 0) THEN SysDirClose(hDir:=hDirHtmlTest); SysFileCopy('/var/www/html/video.htm', '$$PlcLogic$$/Application/video.htm', ADR(dwCopySize)); ELSE .... Die Url-Streams habe ich gelassen wie sie vorgegeben waren: urlStream := CONCAT('http://', CONCAT(sIPAddress, '/video.htm')); urlPicture := CONCAT('http://', CONCAT(sIPAddress, '/cam_pic.php')); In der Webvisu im Browser komme ich maximal dahin wie im Screeshot Video_Visu_1 zu sehen. Also scheint der Link zu video.htm zu klappen. Das der zu cam_pic.php nicht klappt, wundert mich nicht, denn es existiert nicht und wird auch nicht evtl. am rechten Ort angelegt. Ich bin mir vollkommen im Unklaren: muss da was auf dem Raspberry Pi im Hintergrund laufen , z.B. raspivid . Welcher Programmteil bedient die Cam ? Ich erkenne auch nicht, wo ein einzelnes picture entstehen soll. Wäre dankbar, wenn ich hier etwas Hilfe bekommen könnte. Evtl. gibt es Probleme mit der von mir verwendeten Codesys-Version 3.5.20.1 ? Ich benutze einen Raspberry 4 Rev.1.2. Grüße Thomas

Post by kevintumibay on Struggling to connect to EK1100 to Raspberry Pi ^{CODESYS Forge talk (Post)}
SUMMARIZED VERSION OF QUESTION: I'm trying to connect a Raspberry Pi running "Codesys Control for Raspberry Pi" to a Beckhoff EK1100, unfortunately, when I try to connect I get the following messages SEE FIRST PICTURE DETAILED VERSION OF QUESTION: Hi everyone, I'm a college student that is super interested in learning about PLCs. I wanted to dive into the subject and decided to follow this great Instructables article: https://www.instructables.com/Programming-Raspberry-Pi-With-CODESYS/ Thank you in advance for your help! My current setup is as follows: 1. I have Codesys Control for Raspberry Pi, version 4.14.0.0, (https://store.codesys.com/en/codesys-control-for-raspberry-pi-sl.html) installed on a Raspberry Pi 3B. 2. I am using my smartphone hotspot to create a network. 3. I have CODESYS 3.5 SP21 (64 bit) installed on my Windows 11 laptop. 4. Both the Raspberry Pi and my laptop are connected to the smartphone hotspot network (I am wirelessly connecting to the Raspberry Pi). Connecting to the Raspberry Pi from CODESYS on my laptop: 1. I launch Codesys Installer -> I install Codesys Control for Raspberry Pi (link to the software). 2. I launch Codesys 3.5 SP21 (64 bit) on my laptop. 3. I go to file --> new project --> standard project --> in the pop-up I select "Codesys Control for Raspberry Pi" and "Structured Text" 4. I click on tools -> Deploy Control SL (on older versions of Codesys you would click on "update Raspberry Pi", I got that information from this video: link) 5. Inside Deploy Control SL --> I go to the "communication" menu and I input the IP address of my Pi, the password, and click on connect. 6. Inside Deploy Control SL --> I go to the "deployment" menu and I install Codesys Control for Raspberry Pi SL and Codesys Edge Gateway for Linux 7. Now I double click on "device" in the left hand tree and put in the IP address of my Raspberry Pi and click on connect --> success! I am able to connect! SEE SECOND PICTURE Powering the EK1100 and connecting it to the Raspberry Pi: 1. I am supplying the EK1100 with 24 V across the + and - pins. 2. I have jumper wires going from the + pin to the 24V pin and from the - pin to the 0V pin. SEE THIRD PICTURE 4. I am pretty confident that the EK1100 is receiving power because the "LED Us 24 V" and "LED Up 24 V" are lighting up. 5. I then run an ethernet cable from the EK1100 to the Raspberry Pi port (the Raspberry Pi is connected to my laptop wirelessly over WiFi). I think this connection should also be good since the LINK/ACT LED lights up. Trying to connect to the EK1100: 1. Back in Codesys I right-click on "Device" in the left tree and then in the pop up I click on "add device". 2. I then click on EtherCAT Master. 3. Next in a terminal window I SSH into the raspberry Pi and run the "ifconfig" command. 4. From there I get the MAC address for eth0 --> in my case: b8:27:eb:29:a9:25 5. Then, back in Codesys I double click on "EtherCAT Master" in the left hand tree. I then paste the MAC address into the "Source Address (MAC)" field. 6. I go to the Beckhoff official website and download the XML files for EtherCAT: https://www.beckhoff.com/en-en/products/i-o/ethercat-terminals/ek1xxx-bk1xx0-ethercat-coupler/ek1100.html? 7. I unzip those files in my computer into some folder that I can remember. 8. Back in Codesys I click on "Tools" --> "Device Repository" --> "Install" --> and then on the "Beckhoff EK11xx.XML" file. 9. In theory the necessary XML file is now installed. 10. THIS IS WHERE I RUN INTO THE PROBLEM: I then click on login --> I right click on EtherCAT_Master and then scan for devices --> and nothing. 11. It just doesn't detect it. On top of this whenever I login I get those orange triangles on the left on my tree. When I check the Log I get the messages at the very first screenshot of this post. SEE FOURTH PICTURE Solutions that I have tried to resolve this problem: 1. I thought it was maybe the .XML file so I installed all the .XML files from the EtherCAT folder that I downloaded. That didn't fix it. 2. I went on the Wayback Machine and got the .XML files from 2018 as I thought maybe an older version would work. This file of EtherCAT folders had a .XML file named "Beckhoff EKxxxx.XML" I thought this would work because that's the name of the file the guy in the Instructables used (https://www.instructables.com/Programming-Raspberry-Pi-With-CODESYS/). That didn't do anything. 3. I ran the PLC on my computer instead of the Raspberry Pi and tried to connect to the EK1100, in case the issue was with the Raspberry Pi, but I still ran into the same error from the picture above: "Attention! The device was not found in the repository. Vendorcode: 0x0. Productcode: 0x0. Revision: 0x0". SEE FIFTH PICTURE 4. I reinstalled Codesys, I was originally on version 3.5 SP20 when I did this, I upgraded to 3.5 SP21 with no success. 5. I then thought the solution might be to first add the EK1100 hardware before connecting so I did the following: 6. Right click on "EtherCAT Master" on the left hand tree --> then click on "add device" --> then I added the "EK1100 EtherCAT Coupler (2A E-Bus)" MY THEORY OF WHAT IS CAUSING THE PROBLEM: I asked ChatGPT for help and it said that it might have something to do with the revision number. On the physical EK1100 it says "Rev. Nr.: 0018". I believe that this means that I need to a revision 0018 XML file but if you look in Codesys it says the version is 16 (picture above). This is confusing because I got my .XML file from the official Codesys website so it should be the most up to date version possible. I searched and I searched and I couldn't find a version 18 .XML file, I don't even now if this exists. Any help you can provide is greatly appreciated, I don't know what to do anymore and I really really want to get this working. Thank you!

Post by t-probst on Strong Private Key Protection for Encryption Certificates ^{CODESYS Forge talk (Post)}
Hello, We are trying to implement an automated method of adding of a certificate and private key to the Windows certificate store for encrypting CODESYS projects. We want to do this so that users do not have to deal with details of certificates at all and to prevent user error. We are keen on enforcing strong private key protection since it ensures that a password is required for the certificate to be used to decrypt a CODESYS project. When we add a certificate to the certificate store and enable strong key protection using the Microsoft Management Console Certificates snap-in, it works as expected. However, through this method the user may mistakenly not enable strong private key protection. For the certificates we create programmatically (using Microsoft’s Cryptography Next Generation API in .Net 7) bag attributes are added to the certificate and key by the API. These bag attributes are as follows: Bag Attributes localKeyID: 01 00 00 00 subject=C = xx, ST = xxx, O = xxx, OU = xxx, CN = xxx issuer=C = xx, ST = xxx, L = xxx, O = xxx, OU = xxx, CN = xxx -----BEGIN CERTIFICATE----- [encoded certificate] -----END CERTIFICATE----- After using this certificate with bag attributes to encrypt a CODESYS project, it can’t be decrypted, showing this error: "The specified project could not be loaded. Possible reasons might be: - The project file is corrupted or invalid - The project has been saved with a newer version of the programming system. If this is the case, you can open the project in the corresponding version. Choose "Save as..." with the appropriate storage version, and retry again. - You may not have the necessary permissions to lad the project" We know that the bag attributes are causing the issue because if we manually edit the certificate file to remove them before using the certificate to encrypt a project, the project can be decrypted as expected. However, we are unable to automatically enforce strong key protection using this method. Here is a link to a StackOverFlow question that we have posted recently for this issue: https://stackoverflow.com/questions/76922355/enforcing-strong-private-key-protection-for-x509certificate2-objects-in-net-mod Any help is greatly appreciated.
