Build: CODESYS 3.5 SP19 Patch 1 (64-bit) Host OS: Windows 10 Target: Linux SL I have a project with programs in Structured Text and Ladder Diagram. When I try to use the Find function, it works for the Active Editor; however, when I try to use Find for the Entire Project, I get the error "Object reference not set to the instance of an object." I know what this error means in the context of the program, but I have no idea why the find function is returning this error. The variable I am searching does not matter: it happens with all variables. Any help with this will be greatly appreciated. I generally use the Find function quite often as I am developing and not having it is really slowing me down.

Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Hey, Sorry this isn't super helpful, but i had this problem once and was able to resolve it. I can't recall how I solved it and whether it was a problem with my codesys installation or the project itself. If it is the codesys installation, make sure all your required libraries and plugins are installed and available. compare with a colleagues installation if possible. I vaguely recall saving a copy of my project and deleting things one by one until the error went away...

Hello I'm using Codesys V3.5 SP19 Patch 6 and a Raspberry PI 5 4GB Bookworm 32bit with the Runtime 4.11.0.0 SL. I can install the runtime and download the software completly but after a few seconds the connection disconnects with the message no connection to device. Please scan network again. And the object reference was not set to an object instance. See screenshot. Can somebody help me with that? Thanks
