    I am running the latest version of CODESYS V3.5 SP16 Patch 1 (64-BIT) on my laptop I have a Raspberry Pi 4B 1GB platform running CODESYS V3.5.16.10 that has been installed..a few times as well as APT updates and upgrades The issue that I am having is the CODESYS runtime on the Pi will stop running after ~10s - ~30s. I cannot download without first starting the runtime and it will crash soon afterwards. I have also attempted opening a new project and downloading a blank project I have attempted to...

    Sorry for the delay in getting back to you, got buried in a bunch of other work. I looked over what you did, but I ended up sticking with the multiple frame approach. Only for the fact that with the multiple frames, I can set limits when I use "Write Variable" input.

    Why don't you declare the TestWord as a VAR_GLOBAL ? Then you can easily use it in PRG1 & PRG2 without using pointers. Just be careful with running PRG1 or PRG2 in a different task of each other.

    Hello, I have several (PRG) POU's in my Codesys V2.3 program. For example PRG1, and PRG2. Because PRG1 contains an adress which is a Modbus Holding memory, i want a pointer towards that adress. I have a HMI that can read and write that holding memory adress.(For example speed reference) I also have PRG2, which i also want to read and write to that adress. So what i did is: In PRG1: VAR testword AT %MW5480 : WORD; END_VAR In PRG2: VAR ptr_testvar : POINTER TO WORD; END_VAR ptr_testvar := ADR(PRG1.testword);...

    habe noch eine Frage und zwar kann man die "IIoT Libraries SL" auf dem Pixtend verwenden? Bei mir bleibt das Http-Result eines Requests leer.. Also es gibt gar keine Reaktion. (habe alle Geräte aktualisiert) Auf dem Computer mit Codesys Control Win hatte es funktioniert es.

    I assume you mean you have one controller and 4 HMI? The next question I would have is that do you want all 4 HMIs to have control at once or are you looking to only have 1 HMI be in control at any given moment?

    Hi there, i am using CoDeSys 3.5.16.10 with a hardware PLC and a Webvisu. I am using the streaming function to copy images from my webvisu-system to the PLC. This is already running. Actually the problem is that i overwrite existing images and the only way to see them on the webvisu is, to reload the the browser. i tried it also with Bitmap-Version. But after changing the image and incrementing the Bitmap-Version for that image, nothing happens. Does anyone know any solution? PS: I know there is...
