Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Post by pedegani on "Do you really want to perform" dialog boxes ^{CODESYS Forge talk (Post)}
I have the same annoying problem. The confirmation prompt for every single action appeared recently after an update from CODESYS 3.5 SP20 Patch 3 to Patch4, but I don't think it's due to this. Having to confirm every operation while debugging an application is a considerable waste of time and does not help at all to concentrate on development, not to mention that many times you miss the long-awaited event because you are busy looking for the 'yes' button to resume debugging or force a variable. Does anyone know how to disable the confirmation messages?

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 mondinmr on Unexpected behavior in cyclic encoder read method during INT overflow (wrap-around) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m investigating a potential issue with a cyclic method we use for reading incremental encoders in our libraries. I’ve come across two implementations that, at first glance, appear to perform the same operation: motionUnit.vlPositionActualValue is UINT due strange encoder type. Version A METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; rI: INT; delta: INT; END_VAR rI := TO_INT(motionUnit.vlPositionActualValue); delta := rI - actPosFieldOld; m_actPosRaw := m_actPosRaw + TO_LREAL(delta); actPosFieldOld := rI; IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Version B METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; END_VAR m_actPosRaw := m_actPosRaw + TO_LREAL(TO_INT(motionUnit.vlPositionActualValue) - actPosFieldOld); actPosFieldOld := TO_INT(motionUnit.vlPositionActualValue); IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Both use INT and the same delta logic, so they seem equivalent. However, when an overflow (wrap-around) occurs, version A continues correctly as expected, while version B unexpectedly resets to -32768 without a clear reason. Has anyone experienced similar behavior or can shed light on what might be happening here? It almost seems as if the cast to LREAL is being applied before the calculation — but that would be illogical and potentially very dangerous in many situations! Thanks!

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 :)
