Solved! Go to Control Panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change settings. Scroll down the list of applications to CODESYS and CODESYS ControlService. If you do not see this application, add it to the list. Make sure all checkboxes are checked (Domain, Private, and Public).

Post by bbm1995 on Camera RTSP Feed ^{CODESYS Forge talk (Post)}
Can you provide some infos on what you did? What model is your camera and which protocols does it support? Is there a direct link to the feed? Does your camera prevent embedding of the feed (this was my issue.)? I had to use additional software (go2rtc) to be able to stream the feed from an ABUS TVIP48511...

Post by bjarne-pagaard on Unable to add alarm configuration object to project ^{CODESYS Forge talk (Post)}
I believe it should be available. It may be the case, that your device does not support the alarm configuration. Some smaller PLCs sometimes do not support it. You can try changing to a different device, like a Codesys Control Win, in your project, and see if then allows you to add the alarm configuration.

Post by phoward131 on Alarm Table Filtering ^{CODESYS Forge talk (Post)}
I actually just found the solution maybe. If anyone else is running into this, go to your Project Settings > Visualization > Advanced (check 'Visible' to see advanced settings) > UNCHECK 'Activate property handling in all element properties.' I am not sure what else unchecking this might affect but it seems to allow the alarm table to be filtered as expected.

WAGO will use 0-32767 as the raw units. Note a value of 3 means over/under range. Map that IO however you please, then scale in your program using any of the available libraries or with your own simple y=mx+b scaling formula to get to the engineering units you desire. Inverse for the AO to get back to 0-32767.

Post by domebruce on Which database to use? ^{CODESYS Forge talk (Post)}
We have developed a similar application few years ago with .Net and MS Sql Server. The database has about 30 tables, the more bigger tables have 2 or 3 thousands records. We can have multiple threads accessing at the same time to the DB. To garantie the data integrity we need to manage data locks and transactions. Thanks

Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

I am trying to create multiple branches in my project and I keep getting gaps in the ladder logic "wiring". I'm not sure if this is a graphical error or something else but every thing I've tried to do to correct it does not work. Has anyone else run into this or know how to correct it?

I'm trying to open the VisuDialogs.Numpad dialog to enter a new temperature setpoint on one of my VISU screens. For some reason, the numpad dialog does not appear as an option in the Open Dialog dropdown in my input configuration. I'm very new to CODESYS, so sorry if this is a simple fix/known item XD.

Post by timvh on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
If you want to use the Test Manager, I prefer to start all the tests through the scripts of this manager. So open from there the projects, load it and run it. If you also want to use Python scripts to access CODESYS functionality, while executing a Test Manager script, then also start them from the Test Manager commands.

Post by mondinmr on What happened to Python? ^{CODESYS Forge talk (Post)}
What happened to Python? I’ve just installed version 3.5.21.3 of the CODESYS development environment. I’m coming from 3.5.19.5. What happened to Python scripting! We rely heavily on it for the automatic generation of thousands of lines of code! It seems absurd to me that such an important feature has been removed!

Hi @ph0010421 and @Ton, Is it possible to program a stopwatch to measure a system running time when it is turn on, and pause when the system is turn off. I tried your examples when stopped, the elapsed time will then be calculated, but i need the time to be continuously counting. Warmest regards,

Currently started working on codesys i want to know is there any COP instruction with similar functionality in codesys like rockwell. I want to use it to split REAL into 2 INT,DINT to 2 INT also reverse 2 INT into DINT and 2 INT into REAL. Thanks in advance

I just want to highlight, that we intend to use the codesys runtime on an embedded device that has no possibilites to connect any dongle devices to. It is an edge IO-Link master with an 1.6GHz ARM computer running inside that has an embedded linux running and a Docker container engine: https://www.hilscher.com/de/produkte/edge-gateways-mit-container-management/edge-io-link-master
