Post by hyys12 on Help understanding analog in-/outputs ^{CODESYS Forge talk (Post)}
Hello. I am currently working on a WAGO PLC, where I am trying to wrap my head around how the analog inputs and outputs work in codesys. I have looked far and wide on the internet, for a general introduction to the whole concept, but I have not had any luck with finding anything that helped me understand it better. The whole goal is for me to be able to read an analog input from a temperature sensor, as well as using an analog output, to control a frequency inverter. I know these have nothing to do with each other, but that is all I have on hand right now. I am trying to program this using Ladder Diagram. The only thing is, that every video/guide I have seen/read using LD, just adds a whole lot of function blocks, to do all kinds of stuff they don't explain. My general question is, how would one go ahead and read the analog input, as well as transmit an analog output? Is there some kind of specific function block I would have to use for this, or some great video I can watch, to understand the inner workings. Is it somehow possible to see the values the PLC recieved/sends? Regards.

Hey, I am facing the same problem. Basically UA Expert and other programs work fine with the login credentials. But codesys can not use them properly. I can see the server login to it manually but when I download the program and run the datasource never runs... Currently I am facing the same Error ID: 7012 and cant get it running properly.

I had this problem when running the application as a Simulation. When I wrote it to the Pi all worked as expected. If this isn't the case for you, we've seen some issues with sqlite on the Pi's - so reset Origin and re-download may help in that case. Good luck, Mark

yes, sorry this is an accident in current Gateway Version. Either use 3.5.20.0 Version. (download from CODESYS Store standalone setup - https://store.codesys.com/en/codesys-edge-gateway-for-windows.html ) or do it manually by: 1. stop Gateway: 2. Add in c:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSGatewayV3\xxxxxxxx\Gateway.cfg [CmpEdgeGateway] MaintenanceMode=1 3. start Gateway again 4. add it to your CAS Instance

okay, the weird thing is the driver is only continuous running when i enable debug output. if debug is not enabled it's continuous switching from running to not running. i will check again and download the libraries Which versions of libraries do you use, can you send a screenshot?

Hello, I face issues opening old Codesys 3 program when I am having a newer version installed. Unfortunately since I was forced to format my laptop after an unexpected crash. I lost all the setup files of the older versions. Is there ant where I can download it from? BR, Suyash

Post by alexgooi on No Bootproject possible ^{CODESYS Forge talk (Post)}
Hello Simon, Thank you for your response. The problem occurs after about 10 online changes, after this a full download is required, but that means that the installation is going down. Is it possible to enlarge the space reserved for online changes, so that the problem occurs after 100 online changes for example? Kind regards Alex

Colleagues, i have the same problems. At the current time, I have to use the new version of the Codesys (3.5.20.10) + Control for Linux SL 4.11.0.0, but it works unstable : theree are a lot of freezes and not-respondings. I tested this on different projects: those that were created in the current version of the project, and those that were migrated from other versions of the development environment. Compiling a project without connecting to a controller is fast enough. The first downloading of the code into the controller, too. But as soon as you need to make edits and download a new code problems begin. Codesys "freezes" at the "Generation code" stage for 15-20 minutes. And only after that time loads the code into the controller. Previously, we used version 3.5.17.60 + Control for Linux SL 4.7.0.0. The process took 1-2 minutes. Do you have any ideas how can i fix it? I will be grateful for your answers.

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
Hello, I have a new project and I need to connect to a TCP socket using the URL instead of an explicit IP address, myendpoint@mydomain.com Which library is best suited for this? This is for a new enterprise project, the endpoint is a server in a datacenter running some real time application. We have big IP, it will automatically reassign the IP address to the backup server if a crash occurs so an explicit IP won't work for me. I've done this in RS logix, working now to migrate that code over to codesys. Thanks in advance!

Post by abauza on Image Pool using in other libraries ^{CODESYS Forge talk (Post)}
Hi im Albert, im developing libraries for my PLCs and i have some issues on visualization part. First of all I have done a library that have a image pool with a list of 4 gifs "ImagePoolErrors" (i've tested in other projects and it works) but the problem comes when i create another library that in the visualization part contains images from my image pool library, when i simulate a program that includes a instance of my second library object the visualization images dont show, any of them, i've checked all the references and tried some options of the image properties but without any difference. Here is the screenshots of the first library (that contains Image Pool) and the second library (that includes images of the image pool first library) and the visualization simulation (with the missing image gif issue). Any idea of what i forgotten in the process? If you need any detail of the library or of the project or you need the library file, ask me, thank on advance
