For whoever finds this old thread. Instead of System.exit(0), use system.exit(0) without capital 'S', this worked for me. I use these imports from future import print_function import sys import os

Post by jorenbeyl on library inside library ^{CODESYS Forge talk (Post)}
I am currently developing a library that contains real‑time data. To handle this real‑time data, I am using additional libraries called SysTime and SysTypes Interfaces. When I compile my library on its own, no errors occur. However, when I use this library in a project and compile the project, I get an error indicating that the SysTime data type is not recognized. This happens even though the SysTime library is visible as a dependency under my library. Does anyone know how to correctly include a library within another library so that the project recognizes the sub‑library without causing compilation errors?

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne

Post by rikkrt on Limited options ^{CODESYS Forge talk (Post)}
Hi! I was downloading codesys for a school project, but I cannot seem to find where and how to get the other programming languages. When I try to create a new project, I only get the option to program in structured text. *see problemcodesys.png Does anyone know where I can get the other languages? Thanks in advance, Rik

Hi, I have been working on Codesys V3.5 with PFC200 controller and Can Gateway 750-658. I want to convert the incoming CAN data from bytes into UINT and for outgoing data bytes to UINT. Does anyone has experience with this kind of data? I tried few different ways but it doesn't seem to be working.

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.
