Codesys has a motion libraries (SoftMotion), but you need to buy a licence keys for them to work. the most basic one is SoftMotionLight. you just have to select your drive in the device view and add a SoftMotionLight CiA402 axis. then the library is added to your project. You can use the SML_* motion FBs and configure the axis now.

I have found a similar topic but tried to run it in C3.5.16 and the visualization crashed. https://forge.codesys.com/forge/talk/Engineering/thread/8be0f6f14a/ My question is what is the easiest way to run a dialog from ST, as we need an external device to open the dialog so we cannot use the button on the display itself.

I added a main action to an SFC step, and then tried to delete it. There is no delete option in the SFC menu nor in the right click menu of the step. I deleted the action from the device tree, but building results in and error saying the action is not defined. Is there a way to delete a main action?

There are examples installed when you install codesys. they are located in C:\Program Files\CODESYS 3.5.19.50\CODESYS\CODESYS SoftMotion\Examples The examples won't be specific to your drive, though you haven't specified the exact drive. After you add the device to the ethercat master you can click on it and set pdo etc

I have now conducted some tests. The problem occurs when the Python script establishes an OPCUA connection, even if I only establish the connection without reading or writing any data. Is there another way to exchange data between Python and CODESYS without having to put in a lot of effort?

Post by mikek10 on Ethernet/IP 4.6.0 causing exceptions? ^{CODESYS Forge talk (Post)}
Hi, I have a project currently in development, it has a number of Ethernet/IP devices (18 adapter devices with Codesys as scanner, another scanner device with codesys as adapter). This has been stable whilst on factory floor for several months (though prior to that I did have some Ethernet/IP issues which were resolved by adjusting RPI rates). Today I tried updating to Ethernet /IP 4.6.0 from 4.5.1, subsequent to this I had 2 exceptions in a 2 hour period, I reverted to 4.5.1 and have had no further exceptions. Note I do have a device (Zebra printer) that frequently times out and reconnects, this does not seem to cause any issues in operation and does not cause any exceptions with 4.5.1. I believe the root cause of this is on the Zebra side, however there does not seem to be any adjustment I can make to prevent the time outs. Information from device log is in screenshot attached.

Post by mondinmr on First IO address of a CAADiagDeviceDefault. ^{CODESYS Forge talk (Post)}
I have a device CAADiagDeviceDefault: IoConfig_Globals.Axis_A In our library, we perform introspection of the Etc_SlaveDiag. In that case, we have connectors, and by searching for them by address, I can find them in the IO mapping using the offset and size provided by EtherCAT. However, a Lenze i700 drive, instead of placing the IO mapping in the Etc_SlaveDiag device, places it in a sub-device CAADiagDeviceDefault. So, when I perform introspection, I cannot find the IO correspondences. Yet, in the CAADiagDeviceDefault, I do not find the connectors and cannot do the matching. Is there a way with a pointer or reference to a CAADiagDeviceDefault to obtain the address of the first input and the address of the first output? This is because we have our own motion library with many EtherCAT devices that automatically configure the mappings, but I can't manage to do so with the Lenze i700.

Post by lbartik on J1939 TX/RX PDU1 ^{CODESYS Forge talk (Post)}
Is it possible to transmit a PDU1 PGN using the J1939 manager and local device? What if I need to transmit a PGN RQST via 0xEA00 (PGN 59904)? How would I do this P2P (Destination < 0xFF) or broadcast (Destination 0xFF)? I don't think this is possible for any destination type. I don't think it's possible to receive broadcast PDU1 messages either. For example, an address claim PGN 60928 (0x18EEFF80) is addressed to all nodes (0xFF) and not any specific local device so it will be filtered out. These are major oversights in the IoDrvJ1939 library to not support every PDU1 RX/TX scenario. IoDrvJ1939 supported scenario: 1. Receive (RX) PDU1 (P2P) destination-specific (PDU-specific < 255) to local device with matching address IoDrvJ1939 unsupported scenarios: 1. Receive (RX) PDU1 (P2P) global (PDU-specific = 255) 2. Transmit (TX) PDU1 (P2P) global (PDU-specific = 255) 3. Transmit (TX) PDU1 (P2P) destination-specific (PDU-specific < 255)

Post by edvard-munch on How I can get "Done flag" for "Modbus Slave Channel"? ^{CODESYS Forge talk (Post)}
This is from 10 years ago, I know. But I have been using (SLAVE_DEVICE.iChannelIndex = CHANNEL_NUMBER) AND (SLAVE_DEVICE.xDone) I suppose that it shows xDone for the channel that shows up in the iChannelIndex at the same cycle? It seems to be working properly for two devices that I have been using it before But now I have another device and using two write channels, for one register each. One channel works properly and returns DONE flag When another channel is triggered, I see that it shows up in iChannelIndex, but flag DONE not received, but no Error for the channel. Also, when i check the register in the device it's evident that data has been transferred. Is this could happen sometimes with CODESYS, so DONE flag not received? Or this is a problem with a given device? With this certain register

Post by mdetrana on VPLCs Tab 'Grey-ed Out', Cannot Create VPLC ^{CODESYS Forge talk (Post)}
When evaluating Codesys functionality, I found that the VPLC tab under Deploy Control SL > Operation > VPLCs is 'grey-ed out', see attached image. I'm trying to evaluate how my infrastructure will interact with Codesys on a Raspberry Pi 4, so I'm trying to demo running it before purchasing licenses. I was going through the Codesys tutorial here, and it never shows the tab as grey, so I do not know how to proceed. Let me know if I can get any additional information that can help. This could be related to an Info message that's sent when connecting- [INFORMATION] Connected successfully! [INFORMATION] Successfully connected to target (<ip_address>) [INFORMATION] No supported container engine found on device. You have to install a supported container engine to use Virtual Control. Please contact the Administrator of the device. [INFORMATION] Finished reading device information</ip_address> I'm not exactly sure what I would need to do to install a 'supported container engine'.

Post by janderson on OPC UA Server limitations, large array crashes runtime ^{CODESYS Forge talk (Post)}
What are the limitations of the OPC UA Server? I am trying to get data off my PLC that is acquired at high rates (~50k samples/s) so I am storing them in arrays and trying to get the arrays off the PLC. When I attempt to read a ~200k element array through OPC UA the server and runtime crashes (requiring tools -> update linux arm64 -> start runtime). Is there a better way to get highspeed data off? The ACDatalog library seems a bit irritating to use so I would prefer to go through OPC UA.

Post by appling on License status of Linux 64Bit runtime via CLI ^{CODESYS Forge talk (Post)}
Hi, I have a Linux 64Bit system with a Codesys application running on it. It stops after 2hours and a few minutes, which makes me think something is wrong with the installed license. (in my last timing it stopped after 2h4min, on the codesys website it is stated that runtimes without a license stop after 2h) I installed the license via a USB license dongle that I activated on my workstation with the Codesys IDE a while ago. Now the system is shipped at not accessible physically, only remotely via SSH. So is there a way to check the status of the License of the Codesys runtime when it is running on the system? Running the codesyscontrol script with "status" just tells me that it is running, but does not provide any license information. Best regards

Post by xiaolo on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
Does Ver. 4.12 support Raspberry Pi 5? I have three issues. The first issue is that Codesys cannot detect the RPI 5 when I want to download the runtime. When assigning the IP Address manually then I can download the runtime. The second issue is that I cannot connect to the RPI to download a program. Sometimes the window pops up and it ask for the user credentials, but it is still not connecting. The third issue is that I cannot connect to an ESP32 configured as a Modbus Slave with a Raspberry Pi 4B. I can connect to the ESP32 via a Radzio! Modbus Master Simulator. I am also missing the function Write Holding Registers in the setup of the slave. Are this known issues and when it will be solved?

Post by gediminas on Datasource OPC UA client system failure ^{CODESYS Forge talk (Post)}
I am using CODESYS v3.5 SP20 Patch 3 / Control for BeagleboneBlack SL v4.13 and after some time the OPC UA Server crashes. However, Runtime still works without any issues. The events leading up to the OPC server crash are the most suspicious: 1) Mutex deadlock detected - owner thread died, and 2) Runtime received SIGABRT. And it seems very similar with this topic except used versions - issues should be fixed with previous SP's. I can't seem to find any information about these events. Need some pointers in the right direction on how I can fix this problem.

Post by pernockham on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
Using Codesys runtime for Linux and thinking of the process of preparing multiple such systems for my customer. I don't necessarily have physical access to these units, they can be (very) remote. The idea so far is to use an image to install the Linux OS and codesys runtime. Application updates can be done by distribution of the PlcLogic/Application/application.app and application.crc files. But whats the most practical way of managing the license for these units? Do each controller need to be physically connected to a License Manager instance or can licenses be distributed by means of a license file for each unit? I believe that the license should be stored in soft containers for each unit. Help and insights appreciated! Per

Post by mondinmr on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
In Windows I need create shared memory in PC software and connect from CODESYS. If shm is not GLOBAL doesn't work due different users between runtime and PC software. PC software need admin privileges. Name need "Global\\" before key. Very unsafe!!! If CODESYS create shared I cannot find key PC side. In Linux I can create shared memory as standard user, bind in the runtime docker, use keys without any "Global\\". Much more safe!!! If CODESYS create shared you need play with permissions to use app as standard user. I prefer create form PC software as standard user.

Post by toffeebonbon on Die richtige CODESYS-Runtime auf dem Raspberry Pi ausrollen (3.5 SP18) ^{CODESYS Forge talk (Post)}
Guten Morgen, wie der Titel verrät soll es hier um das Ausrollen der CODESYS Runtime auf einem Raspberry Pi gehen. Ob ein klassischer Raspberry Pi aus dem Consumer-Bereich oder ein Compute-Modul spielt in dem Fall keine Rolle. Ich möchte nur anderen Nutzern Hilfestellung geben, die vielleicht ein vergleichbares Problem haben wie ich: Auf Raspberry Pi lief bei mir eine Anwendung, die mit Lizenzen auf einem CODESYS-Dongle lizenziert waren (Multicore-Support und Softmotion). Nach einem Hardware-Defekt habe ich meinen Rasperry Pi gegen eine robustere Lösung getauscht. Ich wollte auf der neuen Hardware die Runtime ausrollen und habe ständig den Fehler gezeigt bekommen, dass die Target- oder Zielsystem-ID nicht stimmt. Für den Raspberry Pi gibt es ja drei verschiedene Optionen der Runtime: 32bit Singlecore (armv6l) 32bit Multicore (armv7l) 64bit Multicore (aarch64) Entscheidend dafür, ob die 32 oder 64 Bit Runtime benötigt wird ist das auf der dem Raspberry Pi installierte Betriebssystem. In meinem Fall hatte ich durch die neue Hardware auch ein aktuellen Betriebsystem-Image aufgespielt, weshalb sich da der Umstieg von 32 auf 64Bit eingeschlichen hatte. In der Entwicklungsumgebung kann über Tools -> Control SL ausrollen das Fenster geöffnet werden, um die richtige Laufzeitumgebung auf dem Steuerungsrechner zu installieren. Bei kleinen Bildschirmen (bei mir ein 15" Laptop) kann der rechte Bereich "abgeschnitten" und das Dropdown-Menü als solches nicht auf den ersten Blick erkennbar sein. Mein Fehler war, dass ich den Scrollbalken nicht gesehen habe! (Bild im Anhang mit freundlicher Genehmigung von Herrn Heberle vom CoDeSys-Support) Nach dem auswählen der jeweils passenden Version kann die Runtime installiert und das Programm wieder geladen werden. Die Lizenzen sind bei mir wieder korrekt erkannt worden und alles läuft wie vorher (nur mit neuer Hardware). Vielen Dank an der Stelle noch mal an die schnelle Hilfe vom Support. Das hat wirklich top funktioniert.

Just to share, for those who as me are seeking for this and had found no information anywhere in this World: Every time I stop/start the PLC runtime ( turning into 'Stopped' or 'Running' state ) the 'CODESYSControlService' appears at the Taskmanager list, which could suggest a straight correlation. I was expecting a clever solution, but this one solves for while.
