Post by abner on Open specific Version of Codesys Control Win V3 x64 ^{CODESYS Forge talk (Post)}
Hi, I have installed different versions of Codesys, 3.5.7 - 3.5.8 - 3.5.16 - 3.5.19. When I create a project in Codesys 3.5.16 and I try to open an instance of Codesys Control Win V3 x64 it always open version 3.5.19, so appear a message windows about versions of devices are different. I have tried to open it from the installation folder and always open the last version 3.5.19 C:\Program Files\CODESYS 3.5.16.0\GatewayPLC C:\Program Files\CODESYS 3.5.19.70\GatewayPLC Does somebody know how to open an specific version of Codesys Control Win V3?

Post by dkugler on Project loses 'Download time' information ^{CODESYS Forge talk (Post)}
and if you copy or transfer a project to another place, copy not only the .project, copy .compileinfo .bootinfo and .bootinfo_guids then we figured out it is more often possible to go online without full download. If you build an archiv and extract it, some of this files are missing and login isn't possible without download. I work with V3.5 SP16 Patch 4. I don't know if this problem of the archiv is solved in newer Versions/SP's and I don't know what the problem of Codesys is to help out a lot of programers of this very annoying problem or at least help with a workaround

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 serwis on Dynamic target position tracking ^{CODESYS Forge talk (Post)}
Hello, I am trying to control a servo drive and dynamically set its position. I control the drive via EtherCAT with a cycle time of 500us. I use the MC_MoveAbsolute block for this. The problem is that when using a PID controller, I generate the positions I want the drive to move to on an ongoing basis, and I would like the position to be set immediately. The MC_MoveAbsolute block must receive a rising edge to execute, and I would like the movement to be performed without waiting for this edge. I have created a function that generates a rising edge every 1 ms, but I am unable to change this time to 500 µs because the TON function does not support times shorter than 1 ms. Below is the code to call the rising edge: IF Exe = TRUE THEN delay1(IN:=TRUE, PT:=T#1MS); IF delay1.Q = TRUE THEN Exe := FALSE; delay1(IN:=FALSE); END_IF END_IF IF Exe = FALSE THEN delay(IN:=TRUE, PT:=T#1MS); IF delay.Q = TRUE THEN Exe := TRUE; delay(IN:=FALSE); END_IF END_IF END_IF Here is the code for calling the MC_MoveAbsolute function: MoveDegree( Axis:= Tilt, Execute:= Exe, Position:= position_target - (base_angle_real * feedforward_turn), Velocity:= vel, Acceleration:= acc, Deceleration:= dec, Jerk:= jerk, Direction:= MC_DIRECTION.shortest, BufferMode:= MC_BUFFER_MODE.Aborting, Done=> , Busy=> , Active=> , CommandAborted=> , Error=> , ErrorID=> ); I realize that there are probably better methods for performing this type of task. How can I implement motion with a dynamically changing setpoint? THANKS

Post by breiter on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Hi, supporting a text based storage format is on our roadmap, see https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html It will be an Add-On feature called "File Based Storage" for the professional developer edition. Structured text POUs will be stored as plain text. Other graphical languages will remain in an xml format. You will be able to switch the storage type for projects. Certain workflows will become easier this way. Nevertheless restrictions will remain because of CODESYS specific storage logic (for example how methods below function blocks are stored as file). So merging using our Git Integration Add-On remains the recommended workflow. A workflow involving Visual Studio Code as the main IDE is not supported. Simply because many topics like library management, task configuration or fieldbus configurators are not available for VS Code. A PLC project is a lot more than just some ST POUs. Best Regards

Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.

Post by brubingh on Download Missing Libraries not working ^{CODESYS Forge talk (Post)}
We are working on a project and the customer required 3.5.16 BF4. After working on the project for a few weeks I opened it the next morning and it could not access libraries. IecVarAccess could not be accessed. I checked if windows updated - it did not. So no explanation for why it lost access other than that I shut down the computer for the night. Note that I am using a demo license. I still haven't figured out any reason to purchase a license. So I spent the next hour reinstalling CodeSys. Note that I did NOT uninstall first. After install I waited another 5 minutes for it to open the first time. I clicked File->Open to open the project. Previously I had selected File->Recent Projects - not sure if that makes and difference. But after this process it did open the project and compile it just fine. This is miserable. If this had happened when I went on site to a customer I would have lost hours of work doing the reinstall. Is there a different and quicker fix?

Post by timvh on Toradex and CODESYS and licensing ^{CODESYS Forge talk (Post)}
For the Virtual Control you need to use a "Network license". The Virtual Control has parameters of which one is the reference to the license server. This can be the device itself, but you need to activate the license on the host system (not in the container). For this, CODESYS has a Network License server with WBM (web based management). See for the Network License configuration: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_license_controller_linux.html If it is only for evaluation, I would advise to use a CODESYS (USB) key and activate the license on the key. Then you still have to install the CODESYS Network License server on the host, but you don't have to activate the license as soft license on the device. The benefit is that you can easily move your license to another device when needed. Off course your device must have a free USB port available to be able to do this.

Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard
