Post by agentcousto on [Bug report] Issue with Importing XML Files Containing "POINTER TO" Variables in Codesys Platform Plugins Versions 2.7 and 2.8 ^{CODESYS Forge talk (Post)}
Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Post by andrej on Creating, using an external Function. ^{CODESYS Forge talk (Post)}
Hello all, I would like to create a simple which runs directly on Control WinV3 x64 3.5.21.0 For this purpose I created a simple dll myAdder.dll in Cpp // MyAdder.cpp // cl /LD /EHsc MyAdder.cpp /Fe:MyAdder.dll #include <windows.h> extern "C" __declspec(dllexport) int __cdecl CmpMyAdder_Add(int a, int b) { return a + b; } I added the dll in the respective folder. Furthermore I "registred" the dll in the CODESYSControl.cfg. However, when I want to use the library I get the error message: Uresolved reference: *'CMPMYADDERADD' * Can you give me a hint what step I missed or where I need to declare the dll, such that the dll resp. the reference can be resolved. Many thanks and kind regards

Post by fedex03 on Read Global Variable from an IoT Device ^{CODESYS Forge talk (Post)}
Hello everyone, I am new to the forum, and to programming with CodeSys. I am dealing with IoT device for industry and I should check if a device is able to read/write global variables in an EtherNet/IP Master. Since I do not have an EtherNet/IP PLC, I thought of using CodeSys as a softPLC. I created a program with a set of global variables (GVL) and a task that increments them. I would like to know if I need to enable any options so that the global variables can be read by IoT devices. My device supports Class 2 Class (Explicit Messaging Connection) communication. Thank you in advance for your help.

Post by micik on Changed Device of Rapberry Pi to MC SL instead of standard SL and cannot connect anymore ^{CODESYS Forge talk (Post)}
I have a test application and use Codesys Control for Rasp Pi SL. I made a mistake and updated device from MSL to MC SL, and now if I try to go online with archived version of the project I gett error message that IDs are different between project device and target device. Of course, I can go online if I changed device in the project from SL to MC SL, but I'm not sure that is correct. So I have two questions: 1. What is the actual difference between MC SL device and standard SL device when it comes to raspberry pi 4? 2. What change I need to do on raspberry pi4 side to change device back from MC SL to SL? Thank you!

Post by bbmussatto on Connetion with Topcon Opus B3 ECO Full display ^{CODESYS Forge talk (Post)}
I have a Topcon Opus B3 ECO Full display and i wanna program it with codesys, but i cant connect it to the display. After creating a new project, i choose the device "Opus B3-B4-B6-3.5.19.50" that is already available in my version of codesys, but i think the problem is that my version of codesys or something else is not the same as the codesys runtime version running on my display. Can anyone tell me how i can see the codesys runtime version on my display? i tried looking in the settings (Daemon > CDS) on the display, but all i see is "N/A" for "Customer Number", "Customer Part Number" and "Customer Serial Number". Can anyone help me make this connection?
