Post by zoronoa on J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup ^{CODESYS Forge talk (Post)}
Hi, I'm trying to monitor a specific PGN which I have it sending a pulse every 500mS Problem: Using the Watchdog for the ECU does not really help me as I have multiple instances with separate PGNs, if a PGN goes ghost, the ECU watchdog won't be flagged as the others will be running. I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
Hello, For my program I need an extended pulse timer, which can be referred to as a retriggerable pulse timer. Where every rising edge of the input resets the elapsed time zero, extending the lenght of the output pulse. The Codesys pulse timer (TP) is a one-shot timer and only resets the elapsed time with the falling edge of the input. There is also a pulse timer (LTP) in codesys, but in my simulation it was also functioning as a one-shot even though the description sounds like LTP should be retriggerable. I have uploaded some timing plots from another PLC program for reference. I am looking for a timer equivalent to the "TEP" diagram. Is there an Extended Pulse Timer in Codesys? Maybe there is a way to manipulate the input so it resets the elapsed time outside the function block?

Post by z870623 on About CPU Loading ^{CODESYS Forge talk (Post)}
I am running a runtime environment on an ARM A35 dual-core processor (1.5GHz) and have encountered some issues. The CPU load (both CPU0 and CPU1) occasionally spikes above 50% before returning to normal, and this happens around 2-3 times per minute. At the same time, I’ve noticed that the Max Cycle Time in the Codesys monitoring screen shows much worse performance compared to the A53 (1.2GHz), with nearly double the cycle time. The optimizations I have made so far are as follows: Set the CPU to performance mode. Isolated CPUs: CPU0 is dedicated to running Linux services and the runtime itself, while CPU1 runs the EtherCAT task and the MainTask. Despite CPU1 only running these two tasks, the utilization still increases above 50%, which I find unreasonable. Additionally, I performed tests using cyclictest both without and with the runtime running. The performance is shown in the following image: From the results, I believe the CPU performance should be fine, but I am unsure why the monitoring results are not as expected. The testing outcomes should ideally be as close as possible to the cyclictest results. Does anyone have related solutions to this issue?

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

Post by fajean on Issue with library updates ^{CODESYS Forge talk (Post)}
We make heavy use of internally developed libraries, which are often nested on multiple levels. I routinely work simultaneously on several libraries along with a project that use them. I make changes to a library and immediately perform a download (online or otherwise) in the project. For the longest time, we had zero issue with this. But starting a good while back, with 3.5 SP19 I think, CODESYS started not noticing library updates in other instances most of the time. When the update is missed, the project sees no need to update the code, and any download ignores the new code. A "Clean all" does not solve the issue. But if I close and then re-open the project, then the new version is noticed and the download works. The other solution is saving the library to the registry multiple times (say, 20-30 times, less if lucky), and then at some point the project notices the changed library. I am now on SP21, and it is still not fixed. This is driving me mad, any tasks probably takes me double the time or more due to this problem. My colleague has the same problem on a separate computer. Is this a known issue? Is there a setting somewhere that changes how updates are checked? Thanks for any help!

Post by mkintegration on Reading Absolute Encoder Position From Yasakawa Drive ^{CODESYS Forge talk (Post)}
I am looking to read in the absolute position of a yaskawa servo drive Sigma 7 that is using absolute encoder. It looks like yaskawa outputs this across there CN1 I/O connecter and during operation just outputs encoder pulses. But at boot up transmits the Multiturn data position and the Position within one rotation (pulse train) on two different wires. Once the drives are enabled it just uses incremental pulses. Does any one have experience with what IEC blocks to use to read this information in. I attached the Yaskawa Manual section that talks about the format.

Hallo zusammen, ich arbeite derzeit an einem Projekt, bei dem ich einen Microcontroller habe, der Messwerte über die SSP0-Schnittstelle an einen Raspberry Pi senden soll. Diese Daten sollen dann in Codesys für eine Soll/Istwert Vergleich/Regelung verwendet werden, und das Ergebnis soll zurück an den Microcontroller geschickt werden. Meine Frage ist, ob es möglich ist, diese Kommunikation über die SSP0-Schnittstelle (als SPI frame format) zu realisieren, oder ob ich auf eine 'reine' SPI-Schnittstelle des uCs zurückzugreifen muss. Gibt es spezielle Dinge, die ich beachten muss, um diese Datenübertragung erfolgreich in Codesys zu implementieren? Ich wäre sehr dankbar für Ratschläge oder Hinweise, wie ich dieses Vorhaben am besten umsetzen kann. Vielen Dank im Voraus!

Post by madskaizer on Task Priority Documentation? ^{CODESYS Forge talk (Post)}
Hi All I was watching the Wago PFC300 webinar ( https://www.wago.com/global/lp-thank-you-onlineseminar-pfc-300 ), and the presenters comment about priority 1 being way above the Ethernet task priority, so that a priority 1 PLC program can actually loose SCADA connection, made me try to round up some hard evidence on Codesys Priorities. I find there is very little information on "correct" task priority configuration. There is a lot of different hardware manufacturers, using Codesys Runtime, that has different descriptions in their manuals on how to set up priority. https://doku.amk-motion.com/en/Subsystems/PDK_202975_A-Serie_en/Content/Projekt/AMKAMAC/PDK_202975_A4-A5_Produktbeschreibung/Funktionalitaet/PLC-Programming/PLC%20Tasks.htm?TocPath=PLC-Programming%7C_____7 https://product-help.schneider-electric.com/Machine%20Expert/V1.1/en/SoMProg/index.htm?#t=SoMProg%2FTask_Editor%2FTask_Editor-7.htm&rhsearch=priority&rhhlterm=priority&rhsyns=%20&SUBSTRSRCH=1 https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_f_task_configuration.html So my questions :) 1) If there is only 1 PLC_PRG task, does priority matter? 2) What is the priority of Ethernet / communication, if nothing is entered? 3) What is the priority of Codesys OPC UA server? 4) Some users here on forge mentions that Wago PLC programs should run as priority 11, but where does this recommendation origin from? 5) What are you recommendations for a relatively slow process, like building automation? It uses OPC UA for communication to SCADA, maybe some MODBUS-RTU and MODBUS-TCP, usually around 100 I/O, been running with everything in a single task at priority 1, 50-100ms cycle time. Some controllers have separate MODBUS tasks, but doesn't seem like a big difference. How would you recommend splitting up communication, IO fieldbus and programs into differently prioritized tasks? I know its a complex matter and all about my application, but I really miss there was just some kind of guidance in the documentations and with all new standard Codesys programs having priority 1 as default, makes it seem less important, than it really is.

I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Post by kevinrn on Github Actions CI/CD tasks - development topic ^{CODESYS Forge talk (Post)}
Hello community, I just want to inform you about our plans and the current status of automating the build process for CODESYS libraries. So it might be helpful for some people who are in the same situation. Background story: I am a software engineer at powerIO GmbH, normally I use high level languages for the products we develop and offer. Sometimes I work with my team on CODESYS libraries, which can also be found in the CODESYS store. Most of the time I spend with them on architecture tasks and tasks that are not directly related to our products. Every time I see the manual processes for releasing a library etc., I am very surprised about this time intensive process. Current situation: I know there has been a scripting interface for years. CODESYS Git was released a few years ago, but the scripting interface was only released a few months (weeks?) ago. We developed a pseudo-automated solution a few months ago, but it was all very hacky. So now there is a better Git implementation and also more modularization and installation options. For example, the CODESYS installer has a full CLI, which makes it very convenient to install CODESYS installations headless. Plans: I think it's the right time to develop a better automation solution. Most of our software projects are hosted on Github and we use Github actions very intensively for other software projects. Therefore, we have decided to use Github for our CODESYS library projects as well. Following tasks should be implemented in automation for CI/CD tasks: - Automated setup of CODESYS installation (Already released: https://github.com/marketplace/actions/setup-codesys-installation) - Checkout CODESYS libraries - Execute tests scripts - Sign CODESYS libraries - Extract Library documentation - Create CODESYS package - Sign CODESYS package Side Note: - This is mainly a side project, and we do not provide support for the CI/CD part. - This topic is here to help and also to get help from other software engineers. - This project and idea is not prioritized as I am currently the only one working on it and I hope it will help us and also others and increase productivity. - We are putting this out there as an organization, but priorities can change quickly and the CI/CD tasks I am developing are mostly done in my spare time. So please don't expect this to happen in a short time or even be fully completed. I would be very happy if some ppl will join the development process and might be open to discuss some technical details for this. I hope this topic is not to off-topic, but I think the CI/CD part is very important today and it can increase a lot of quality and push productivity. Thanks :)

I find this https://us.store.codesys.com/media/n98_media_assets/files/000013-F/0/Multiple%20Applications_en.pdf, that talks about exactly what I want to do, but I can't find the download. The main reason I want to do this is for download speed. Right now it takes at least a minute to download our application to the PLC. A simple program downloads to the PLC in a very short time, but add visualization and the download time gets much longer. If I could download the program separately from the visualization I think that a simple program change would take very little time to download. I have tried create a GVL in the POUs view. This partly works in that both applications can see the GVL, but they each create their own instance of it and the variables are not shared between the two apps. There are ideas of using OPCUA but this raises problems with licensing and having to move any variable that needs to be shared into the Symbol Configuration. This adds a lot of management to keep this up to date. Any ideas would be appreciated thanks.
