Post by stribor on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
I am designing a custom slider object and i ran into a problem when i want to use properties with it. I can update the basic variables if i have a slider variable defined as VAR_IN_OUT, but it does not work with properties. How can i achieve same functionality that some basic objects have (for example basic Slider that comes withing the codesys libraries) such that i can pass both variables and properties to it and they can be modified within the object? I am using Codesys V3.5 SP20 Patch 5.

Post by wedahitha on Could not open library 'SysSocket23, ^{CODESYS Forge talk (Post)}
Hi there, I am trying to open a codesys project done by someone else and Once I install all the libraries I get this error [ERROR] : Library Manager [PROJECT 01: PLC Logic: Application]: Could not open library 'SysSocket23, * (System)'. (Reason: The library 'SysSocket23, * (System)' has not been installed to the system.) SysSocket23 is a standard library and I also tried using the same OSCAT library which was from the original computer that made this code. Using CODESYS V3.5 SP18 Patch 2 Please help me how to solve this problem.

You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.

Post by timvh on Version management ^{CODESYS Forge talk (Post)}
This depends on what you want to achieve with installing the latest version and how you manage your projects and repositories. Maybe you also want to update your device (right click on it to update) or maybe your device is depending on certain versions of libraries (go to the library manager in your project and download the missing libraries). An option is also to first create a projectarchive of the current project you have before you install a new version of CODESYS. Then you can open this projectarchive in the new CODESYS version. Especially if you install the latest version of CODESYS in a Sandbox.
