Post by keith on Ethernet Adapter issues ^{CODESYS Forge talk (Post)}
I uploaded this project and it was running. After upload I had to re-download to get the system to sync up. I now have this fault and am not sure how to resolve it.

Post by ulvis on IDE chrashes when importing OPC UA ECM model ^{CODESYS Forge talk (Post)}
I can import some OPC UA information models, allright. Like the UA (core), Scheduler and PNEM models, etc. However, when I try to import the ECM model (Energy Consumption Managment), the Codesys IDE goes down after a while. Any clues?

Post by athuum on Error 'Library not found' and 'Unkown type' ^{CODESYS Forge talk (Post)}
Hello, I am getting the following error and warning when trying to download a project into a PLC: - Library CmpTargetVisu has not been added to the Library manager, or no valid license could be found - Unkown type: 'CmpEventMgr.EventParam' As far as I can see, both are included, and licensed, in the library manager (see image). What could the problem be, and how would I resolve this?

Post by aria13 on Has anyone fed ESP32 sensor data into CODESYS (via MQTT/Modbus)? ^{CODESYS Forge talk (Post)}
Has anyone tried sending live sensor data from an ESP32 into a CODESYS runtime (for example via MQTT gateway or a Modbus bridge) to trigger PLC logic? I was reading an ESP32 → MQTT tutorial (https://www.theengineeringprojects.com/2021/11/esp32-mqtt.html) that shows how easy it is to publish sensor data from an ESP32, and I’m wondering how practical that is when tying the stream into industrial control software like CODESYS. I’ve also seen Arduino forum threads where people relay sensor streams to MQTT brokers and Raspberry Pi projects that bridge MQTT→Modbus, so I’m mainly curious about real-world issues: reliability, message latency, and simple patterns you’d recommend for safe PLC integration. Any tips, examples, or gotchas from folks who’ve done this?

Post by martinlithlith on Raspberry Pi: List of available drivers / libraries ^{CODESYS Forge talk (Post)}
As most of the posts are moved here around 2015, what would be the right version of codesys to run? Would it be better to install a older version of codesys or should i keep on downgrading libraries? Is there any work done to update theses libraries? It´s been a few years since the last update in this post, are there new libraries/devices for raspberry being added/posted somewhere else? Thanks, Martin
