Do you think there'd be a way to turn this into a library? How would I2C_master be passed down to POU FBs?

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
The RTE will take the RTE license. The HMI will take the HMI license. For the Application Based Licenses, the Runtime will take the smallest which is required. So if you have an application running EtherCAT and no visualization, only the Control with support for EtherCAT is used. If you have another runtime which requires the visualization, it will take the smallest Control license which is required and available + the smallest visualization license which is required.

Post by yannick on Raspberry PI 5 not working ^{CODESYS Forge talk (Post)}
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

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!

Maybe your slave device didn't properly closed its socket port and CODESYS is unable to reconnect? Did you restart your slave device?
